B.1.1. How to Determine What Is Causing a Problem

When you run into a problem, the first thing you should do is to find out which program or piece of equipment is causing it:

If you have one of the following symptoms, then it is probably a hardware problems (such as memory, motherboard, CPU, or hard disk) or kernel problem:
- The keyboard doesn't work. This can normally be checked by pressing the Caps Lock key. If the Caps Lock light doesn't change, you have to replace your keyboard. (Before doing this, you should try to restart your computer and check all cables to the keyboard.)
- The mouse pointer doesn't move.
- The machine doesn't answer to a remote machine's pings.
- Other programs that are not related to MySQL don't behave correctly.
- Your system restarted unexpectedly. (A faulty user-level program should never be able to take down your system.)
In this case, you should start by checking all your cables and run some diagnostic tool to check your hardware! You should also check whether there are any patches, updates, or service packs for your operating system that could likely solve your problem. Check also that all your libraries (such as glibc) are up to date.
It's always good to use a machine with ECC memory to discover memory problems early.
If your keyboard is locked up, you may be able to recover by logging in to your machine from another machine and executing kbd_mode -a.
Please examine your system log file (/var/log/messages or similar) for reasons for your problem. If you think the problem is in MySQL, you should also examine MySQL's log files. See 「MySQL サーバログ」.
If you don't think you have hardware problems, you should try to find out which program is causing problems. Try using top, ps, Task Manager, or some similar program, to check which program is taking all CPU or is locking the machine.
Use top, df, or a similar program to check whether you are out of memory, disk space, file descriptors, or some other critical resource.
If the problem is some runaway process, you can always try to kill it. If it doesn't want to die, there is probably a bug in the operating system.

If after you have examined all other possibilities and you have concluded that the MySQL server or a MySQL client is causing the problem, it's time to create a bug report for our mailing list or our support team. In the bug report, try to give a very detailed description of how the system is behaving and what you think is happening. You should also state why you think that MySQL is causing the problem. Take into consideration all the situations in this chapter. State any problems exactly how they appear when you examine your system. Use the 「copy and paste」 method for any output and error messages from programs and log files.

Try to describe in detail which program is not working and all symptoms you see. We have in the past received many bug reports that state only 「the system doesn't work.」 This doesn't provide us with any information about what could be the problem.

If a program fails, it's always useful to know the following information:

Has the program in question made a segmentation fault (did it dump core)?
Is the program taking up all available CPU time? Check with top. Let the program run for a while, it may simply be evaluating something computationally intensive.
If the mysqld server is causing problems, can you get any response from it with mysqladmin -u root ping or mysqladmin -u root processlist?
What does a client program say when you try to connect to the MySQL server? (Try with mysql, for example.) Does the client jam? Do you get any output from the program?

When sending a bug report, you should follow the outline described in 「質問またはバグの報告」.

This section lists some errors that users frequently encounter when running MySQL programs. Although the problems show up when you try to run client programs, the solutions to many of the problems involves changing the configuration of the MySQL server.

B.1.2.1. `Access denied`

An Access denied error can have many causes. Often the problem is related to the MySQL accounts that the server allows client programs to use when connecting. See 「Access denied エラーの原因」, and 「権限システムの機能」.

B.1.2.2. `Can't connect to [local] MySQL server`

B.1.2.2.1. Connection to MySQL Server Failing on Windows

A MySQL client on Unix can connect to the mysqld server in two different ways: By using a Unix socket file to connect through a file in the filesystem (default /tmp/mysql.sock), or by using TCP/IP, which connects through a port number. A Unix socket file connection is faster than TCP/IP, but can be used only when connecting to a server on the same computer. A Unix socket file is used if you don't specify a hostname or if you specify the special hostname localhost.

If the MySQL server is running on Windows 9x or Me, you can connect only via TCP/IP. If the server is running on Windows NT, 2000, XP, or 2003 and is started with the --enable-named-pipe option, you can also connect with named pipes if you run the client on the host where the server is running. The name of the named pipe is MySQL by default. If you don't give a hostname when connecting to mysqld, a MySQL client first tries to connect to the named pipe. If that doesn't work, it connects to the TCP/IP port. You can force the use of named pipes on Windows by using . as the hostname.

The error (2002) Can't connect to ... normally means that there is no MySQL server running on the system or that you are using an incorrect Unix socket filename or TCP/IP port number when trying to connect to the server.

The error (2003) Can't connect to MySQL server on 'server' (10061) indicates that the network connection has been refused. You should check that there is a MySQL server running, that it has network connections enabled, the network port you specified is the one configured on the server, and that the TCP/IP port you are using has not been blocked by a firewall or port blocking service.

Start by checking whether there is a process named mysqld running on your server host. (Use ps xa | grep mysqld on Unix or the Task Manager on Windows.) If there is no such process, you should start the server. See 「MySQL サーバの起動とトラブルシューティング」.

If a mysqld process is running, you can check it by trying the following commands. The port number or Unix socket filename might be different in your setup. host_ip represents the IP number of the machine where the server is running.

shell> mysqladmin version
shell> mysqladmin variables
shell> mysqladmin -h `hostname` version variables
shell> mysqladmin -h `hostname` --port=3306 version
shell> mysqladmin -h host_ip version
shell> mysqladmin --protocol=socket --socket=/tmp/mysql.sock version

Note the use of backticks rather than forward quotes with the hostname command; these cause the output of hostname (that is, the current hostname) to be substituted into the mysqladmin command. If you have no hostname command or are running on Windows, you can manually type the hostname of your machine (without backticks) following the -h option. You can also try -h 127.0.0.1 to connect with TCP/IP to the local host.

Here are some reasons the Can't connect to local MySQL server error might occur:

mysqld is not running. Check your operating system's process list to ensure the mysqld process is present.
You're running a MySQL server on Windows with many TCP/IP connections to it. If you're experiencing that quite often your clients get that error, you can find a workaround here: 「Connection to MySQL Server Failing on Windows」.
You are running on a system that uses MIT-pthreads. If you are running on a system that doesn't have native threads, mysqld uses the MIT-pthreads package. See 「MySQL Community Server がサポートしているオペレーティングシステム」. However, not all MIT-pthreads versions support Unix socket files. On a system without socket file support, you must always specify the hostname explicitly when connecting to the server. Try using this command to check the connection to the server:
```
shell> mysqladmin -h `hostname` version
```
Someone has removed the Unix socket file that mysqld uses (/tmp/mysql.sock by default). For example, you might have a cron job that removes old files from the /tmp directory. You can always run mysqladmin version to check whether the Unix socket file that mysqladmin is trying to use really exists. The fix in this case is to change the cron job to not remove mysql.sock or to place the socket file somewhere else. See 「How to Protect or Change the MySQL Unix Socket File」.
You have started the mysqld server with the --socket=/path/to/socket option, but forgotten to tell client programs the new name of the socket file. If you change the socket pathname for the server, you must also notify the MySQL clients. You can do this by providing the same --socket option when you run client programs. You also need to ensure that clients have permission to access the mysql.sock file. To find out where the socket file is, you can do:
```
shell> netstat -ln | grep mysql
```
See 「How to Protect or Change the MySQL Unix Socket File」.
You are using Linux and one server thread has died (dumped core). In this case, you must kill the other mysqld threads (for example, with kill or with the mysql_zap script) before you can restart the MySQL server. See 「What to Do If MySQL Keeps Crashing」.
The server or client program might not have the proper access privileges for the directory that holds the Unix socket file or the socket file itself. In this case, you must either change the access privileges for the directory or socket file so that the server and clients can access them, or restart mysqld with a --socket option that specifies a socket filename in a directory where the server can create it and where client programs can access it.

If you get the error message Can't connect to MySQL server on some_host, you can try the following things to find out what the problem is:

Check whether the server is running on that host by executing telnet some_host 3306 and pressing the Enter key a couple of times. (3306 is the default MySQL port number. Change the value if your server is listening to a different port.) If there is a MySQL server running and listening to the port, you should get a response that includes the server's version number. If you get an error such as telnet: Unable to connect to remote host: Connection refused, then there is no server running on the given port.
If the server is running on the local host, try using mysqladmin -h localhost variables to connect using the Unix socket file. Verify the TCP/IP port number that the server is configured to listen to (it is the value of the port variable.)
Make sure that your mysqld server was not started with the --skip-networking option. If it was, you cannot connect to it using TCP/IP.
Check to make sure that there is no firewall blocking access to MySQL. Your firewall may be configured on the basis of the application being executed, or the post number used by MySQL for communication (3306 by default).
Under Linux or Unix, check your IP tables (or similar) configuration to ensure that the port has not been blocked.
Under Windows, applications such as ZoneAlarm and the Windows XP personal firewall may need to be configured to allow external access to a MySQL server.
If you are running under Linux and Security-Enhanced Linux (SELinux) is enabled, make sure you have disabled SELinux protection for the mysqld process.

B.1.2.2.1. `Connection to MySQL Server Failing on Windows`

When you're running a MySQL server on Windows with many TCP/IP connections to it, and you're experiencing that quite often your clients get a Can't connect to MySQL server error, the reason might be that Windows doesn't allow for enough ephemeral (short-lived) ports to serve those connections.

By default, Windows allows 5000 ephemeral (short-lived) TCP ports to the user. After any port is closed it will remain in a TIME_WAIT status for 120 seconds. This status allows the connection to be reused at a much lower cost than reinitializing a brand new connection. However, the port will not be available again until this time expires.

With a small stack of available TCP ports (5000) and a high number of TCP ports being open and closed over a short period of time along with the TIME_WAIT status you have a good chance for running out of ports. There are two ways to address this problem:

Reduce the number of TCP ports consumed quickly by investigating connection pooling or persistent connections where possible
Tune some settings in the Windows registry (see below)

IMPORTANT: The following procedure involves modifying the Windows registry. Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs. For information about how to back up, restore, and edit the registry, view the following article in the Microsoft Knowledge Base: http://support.microsoft.com/kb/256986/EN-US/.

Start Registry Editor (Regedt32.exe).

Locate the following key in the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

On the Edit menu, click Add Value, and then add the following registry value:
```
Value Name: MaxUserPort
Data Type: REG_DWORD
Value: 65534
```
This sets the number of ephemeral ports available to any user. The valid range is between 5000 and 65534 (decimal). The default value is 0x1388 (5000 decimal).
On the Edit menu, click Add Value, and then add the following registry value:
```
Value Name: TcpTimedWaitDelay
Data Type: REG_DWORD
Value: 30
```
This sets the number of seconds to hold a TCP port connection in TIME_WAIT state before closing. The valid range is between 0 (zero) and 300 (decimal). The default value is 0x78 (120 decimal).
Quit Registry Editor.
Reboot the machine.

Note: Undoing the above should be as simple as deleting the registry entries you've created.

B.1.2.3. `Client does not support authentication protocol`

MySQL 5.1 uses an authentication protocol based on a password hashing algorithm that is incompatible with that used by older (pre-4.1) clients. If you upgrade the server from 4.0, attempts to connect to it with an older client may fail with the following message:

shell> mysql
Client does not support authentication protocol requested
by server; consider upgrading MySQL client

To solve this problem, you should use one of the following approaches:

Upgrade all client programs to use a 4.1.1 or newer client library.
When connecting to the server with a pre-4.1 client program, use an account that still has a pre-4.1-style password.
Reset the password to pre-4.1 style for each user that needs to use a pre-4.1 client program. This can be done using the SET PASSWORD statement and the OLD_PASSWORD() function:
```
mysql> SET PASSWORD FOR
    -> 'some_user'@'some_host' = OLD_PASSWORD('newpwd');
```
Alternatively, use UPDATE and FLUSH PRIVILEGES:
```
mysql> UPDATE mysql.user SET Password = OLD_PASSWORD('newpwd')
    -> WHERE Host = 'some_host' AND User = 'some_user';
mysql> FLUSH PRIVILEGES;
```
Substitute the password you want to use for 「newpwd」 in the preceding examples. MySQL cannot tell you what the original password was, so you'll need to pick a new one.
Tell the server to use the older password hashing algorithm:
1. Start mysqld with the --old-passwords option.
2. Assign an old-format password to each account that has had its password updated to the longer 4.1 format. You can identify these accounts with the following query:
```
mysql> SELECT Host, User, Password FROM mysql.user
    -> WHERE LENGTH(Password) > 16;
```
  For each account record displayed by the query, use the Host and User values and assign a password using the OLD_PASSWORD() function and either SET PASSWORD or UPDATE, as described earlier.

Note: In older versions of PHP, the mysql extension does not support the authentication protocol in MySQL 4.1.1 and higher. This is true regardless of the PHP version being used. If you wish to use the mysql extension with MySQL 4.1 or newer, you may need to follow one of the options discussed above for configuring MySQL to work with old clients. The mysqli extension (stands for "MySQL, Improved"; added in PHP 5) is compatible with the improved password hashing employed in MySQL 4.1 and higher, and no special configuration of MySQL need be done to use this MySQL client library. For more information about the mysqli extension, see http://php.net/mysqli.

It may also be possible to compile the older mysql extension against the new MySQL client library. This is beyond the scope of this Manual; consult the PHP documentation for more information. You also be able to obtain assistance with these issues in our MySQL with PHP forum.

For additional background on password hashing and authentication, see 「MySQL 4.1 のパスワードハッシュ」.

B.1.2.4. Password Fails When Entered Interactively

MySQL client programs prompt for a password when invoked with a --password or -p option that has no following password value:

shell> mysql -u user_name -p
Enter password:

On some systems, you may find that your password works when specified in an option file or on the command line, but not when you enter it interactively at the Enter password: prompt. This occurs when the library provided by the system to read passwords limits password values to a small number of characters (typically eight). That is a problem with the system library, not with MySQL. To work around it, change your MySQL password to a value that is eight or fewer characters long, or put your password in an option file.

B.1.2.5. `Host 'host_name' is blocked`

If you get the following error, it means that mysqld has received many connect requests from the host 'host_name' that have been interrupted in the middle:

Host 'host_name' is blocked because of many connection errors.
Unblock with 'mysqladmin flush-hosts'

The number of interrupted connect requests allowed is determined by the value of the max_connect_errors system variable. After max_connect_errors failed requests, mysqld assumes that something is wrong (for example, that someone is trying to break in), and blocks the host from further connections until you execute a mysqladmin flush-hosts command or issue a FLUSH HOSTS statement. See 「システム変数」.

By default, mysqld blocks a host after 10 connection errors. You can adjust the value by starting the server like this:

shell> mysqld_safe --max_connect_errors=10000 &

If you get this error message for a given host, you should first verify that there isn't anything wrong with TCP/IP connections from that host. If you are having network problems, it does you no good to increase the value of the max_connect_errors variable.

B.1.2.6. `Too many connections`

If you get a Too many connections error when you try to connect to the mysqld server, this means that all available connections are in use by other clients.

The number of connections allowed is controlled by the max_connections system variable. Beginning with MySQL 5.1.15, its default value is 151 to improve performance when MySQL is used with the Apache Web server. (Previously, the default was 100.) If you need to support more connections, you should restart mysqld with a larger value for this variable.

MySQL Enterprise Subscribers to the MySQL Network Monitoring and Advisory Service receive advice on dynamically configuring the max_connections variable — avoiding failed connection attempts. For more information see, http://www.mysql.com/products/enterprise/advisors.html.

mysqld actually allows max_connections+1 clients to connect. The extra connection is reserved for use by accounts that have the SUPER privilege. By granting the SUPER privilege to administrators and not to normal users (who should not need it), an administrator can connect to the server and use SHOW PROCESSLIST to diagnose problems even if the maximum number of unprivileged clients are connected. See 「SHOW PROCESSLIST 構文」.

The maximum number of connections MySQL can support depends on the quality of the thread library on a given platform. Linux or Solaris should be able to support 500-1000 simultaneous connections, depending on how much RAM you have and what your clients are doing. Static Linux binaries provided by MySQL AB can support up to 4000 connections.

B.1.2.7. `Out of memory`

If you issue a query using the mysql client program and receive an error like the following one, it means that mysql does not have enough memory to store the entire query result:

mysql: Out of memory at line 42, 'malloc.c'
mysql: needed 8136 byte (8k), memory in use: 12481367 bytes (12189k)
ERROR 2008: MySQL client ran out of memory

To remedy the problem, first check whether your query is correct. Is it reasonable that it should return so many rows? If not, correct the query and try again. Otherwise, you can invoke mysql with the --quick option. This causes it to use the mysql_use_result() C API function to retrieve the result set, which places less of a load on the client (but more on the server).

B.1.2.8. `MySQL server has gone away`

This section also covers the related Lost connection to server during query error.

The most common reason for the MySQL server has gone away error is that the server timed out and closed the connection. In this case, you normally get one of the following error codes (which one you get is operating system-dependent):

Error Code	Description
`CR_SERVER_GONE_ERROR`	The client couldn't send a question to the server.
`CR_SERVER_LOST`	The client didn't get an error when writing to the server, but it didn't get a full answer (or any answer) to the question.

By default, the server closes the connection after eight hours if nothing has happened. You can change the time limit by setting the wait_timeout variable when you start mysqld. See 「システム変数」.

If you have a script, you just have to issue the query again for the client to do an automatic reconnection. This assumes that you have automatic reconnection in the client enabled (which is the default for the mysql command-line client).

Some other common reasons for the MySQL server has gone away error are:

You (or the db administrator) has killed the running thread with a KILL statement or a mysqladmin kill command.
You tried to run a query after closing the connection to the server. This indicates a logic error in the application that should be corrected.
A client application running on a different host does not have the necessary privileges to connect to the MySQL server from that host.
You got a timeout from the TCP/IP connection on the client side. This may happen if you have been using the commands: mysql_options(..., MYSQL_OPT_READ_TIMEOUT,...) or mysql_options(..., MYSQL_OPT_WRITE_TIMEOUT,...). In this case increasing the timeout may help solve the problem.
You have encountered a timeout on the server side and the automatic reconnection in the client is disabled (the reconnect flag in the MYSQL structure is equal to 0).
You are using a Windows client and the server had dropped the connection (probably because wait_timeout expired) before the command was issued.
The problem on Windows is that in some cases MySQL doesn't get an error from the OS when writing to the TCP/IP connection to the server, but instead gets the error when trying to read the answer from the connection.
Prior to MySQL 5.1.8, even if the reconnect flag in the MYSQL structure is equal to 1, MySQL does not automatically reconnect and re-issue the query as it doesn't know if the server did get the original query or not.
The solution to this is to either do a mysql_ping on the connection if there has been a long time since the last query (this is what MyODBC does) or set wait_timeout on the mysqld server so high that it in practice never times out.
You can also get these errors if you send a query to the server that is incorrect or too large. If mysqld receives a packet that is too large or out of order, it assumes that something has gone wrong with the client and closes the connection. If you need big queries (for example, if you are working with big BLOB columns), you can increase the query limit by setting the server's max_allowed_packet variable, which has a default value of 1MB. You may also need to increase the maximum packet size on the client end. More information on setting the packet size is given in 「Packet too large」.
An INSERT or REPLACE statement that inserts a great many rows can also cause these sorts of errors. Either one of these statements sends a single request to the server irrespective of the number of rows to be inserted; thus, you can often avoid the error by reducing the number of rows sent per INSERT or REPLACE.
You also get a lost connection if you are sending a packet 16MB or larger if your client is older than 4.0.8 and your server is 4.0.8 and above, or the other way around.
It is also possible to see this error if hostname lookups fail (for example, if the DNS server on which your server or network relies goes down). This is because MySQL is dependent on the host system for name resolution, but has no way of knowing whether it is working — from MySQL's point of view the problem is indistinguishable from any other network timeout.
You may also see the MySQL server has gone away error if MySQL is started with the --skip-networking option.
Another networking issue that can cause this error occurs if if the MySQL port (default 3306) is blocked by your firewall, thus preventing any connections at all to the MySQL server.
You can also encounter this error with applications that fork child processes, all of which try to use the same connection to the MySQL server. This can be avoided by using a separate connection for each child process.
You have encountered a bug where the server died while executing the query.

You can check whether the MySQL server died and restarted by executing mysqladmin version and examining the server's uptime. If the client connection was broken because mysqld crashed and restarted, you should concentrate on finding the reason for the crash. Start by checking whether issuing the query again kills the server again. See 「What to Do If MySQL Keeps Crashing」.

You can get more information about the lost connections by starting mysqld with the --log-warnings=2 option. This logs some of the disconnected errors in the hostname.err file. See 「エラーログ」.

If you want to create a bug report regarding this problem, be sure that you include the following information:

Indicate whether the MySQL server died. You can find information about this in the server error log. See 「What to Do If MySQL Keeps Crashing」.
If a specific query kills mysqld and the tables involved were checked with CHECK TABLE before you ran the query, can you provide a reproducible test case? See Making a Test Case If You Experience Table Corruption.
What is the value of the wait_timeout system variable in the MySQL server? (mysqladmin variables gives you the value of this variable.)
Have you tried to run mysqld with the --log option to determine whether the problem query appears in the log?

B.1.2.9. `Packet too large`

A communication packet is a single SQL statement sent to the MySQL server, a single row that is sent to the client, or a binary log event sent from a master replication server to a slave.

The largest possible packet that can be transmitted to or from a MySQL 5.1 server or client is 1GB.

When a MySQL client or the mysqld server receives a packet bigger than max_allowed_packet bytes, it issues a Packet too large error and closes the connection. With some clients, you may also get a Lost connection to MySQL server during query error if the communication packet is too large.

Both the client and the server have their own max_allowed_packet variable, so if you want to handle big packets, you must increase this variable both in the client and in the server.

If you are using the mysql client program, its default max_allowed_packet variable is 16MB. To set a larger value, start mysql like this:

shell> mysql --max_allowed_packet=32M

That sets the packet size to 32MB.

The server's default max_allowed_packet value is 1MB. You can increase this if the server needs to handle big queries (for example, if you are working with big BLOB columns). For example, to set the variable to 16MB, start the server like this:

shell> mysqld --max_allowed_packet=16M

You can also use an option file to set max_allowed_packet. For example, to set the size for the server to 16MB, add the following lines in an option file:

[mysqld]
max_allowed_packet=16M

It is safe to increase the value of this variable because the extra memory is allocated only when needed. For example, mysqld allocates more memory only when you issue a long query or when mysqld must return a large result row. The small default value of the variable is a precaution to catch incorrect packets between the client and server and also to ensure that you do not run out of memory by using large packets accidentally.

You can also get strange problems with large packets if you are using large BLOB values but have not given mysqld access to enough memory to handle the query. If you suspect this is the case, try adding ulimit -d 256000 to the beginning of the mysqld_safe script and restarting mysqld.

B.1.2.10. Communication Errors and Aborted Connections

The server error log can be a useful source of information about connection problems. See 「エラーログ」. If you start the server with the --log-warnings option, you might find messages like this in your error log:

010301 14:38:23  Aborted connection 854 to db: 'users' user: 'josh'

If Aborted connections messages appear in the error log, the cause can be any of the following:

The client program did not call mysql_close() before exiting.
The client had been sleeping more than wait_timeout or interactive_timeout seconds without issuing any requests to the server. See 「システム変数」.
The client program ended abruptly in the middle of a data transfer.

When any of these things happen, the server increments the Aborted_clients status variable.

The server increments the Aborted_connects status variable when the following things happen:

A client doesn't have privileges to connect to a database.
A client uses an incorrect password.
A connection packet doesn't contain the right information.
It takes more than connect_timeout seconds to get a connect packet. See 「システム変数」.

If these kinds of things happen, it might indicate that someone is trying to break into your server!

MySQL Enterprise For reasons of security and performance the advisors provided by the MySQL Network Monitoring and Advisory Service pay special attention to the Aborted_connections status variable. For more information see, http://www.mysql.com/products/enterprise/advisors.html.

Other reasons for problems with aborted clients or aborted connections:

Use of Ethernet protocol with Linux, both half and full duplex. Many Linux Ethernet drivers have this bug. You should test for this bug by transferring a huge file via FTP between the client and server machines. If a transfer goes in burst-pause-burst-pause mode, you are experiencing a Linux duplex syndrome. The only solution is switching the duplex mode for both your network card and hub/switch to either full duplex or to half duplex and testing the results to determine the best setting.
Some problem with the thread library that causes interrupts on reads.
Badly configured TCP/IP.
Faulty Ethernets, hubs, switches, cables, and so forth. This can be diagnosed properly only by replacing hardware.
The max_allowed_packet variable value is too small or queries require more memory than you have allocated for mysqld. See 「Packet too large」.

B.1.2.11. `The table is full`

The maximum effective table size for MySQL databases is usually determined by operating system constraints on file sizes, not by MySQL internal limits. The following table lists some examples of operating system file-size limits. This is only a rough guide and is not intended to be definitive. For the most up-to-date information, be sure to check the documentation specific to your operating system.

Operating System	File-size Limit
Win32 w/ FAT/FAT32	2GB/4GB
Win32 w/ NTFS	2TB (possibly larger)
Linux 2.2-Intel 32-bit	2GB (LFS: 4GB)
Linux 2.4+	(using ext3 filesystem) 4TB
Solaris 9/10	16TB
MacOS X w/ HFS+	2TB
NetWare w/NSS filesystem	8TB

Windows users, please note that FAT and VFAT (FAT32) are not considered suitable for production use with MySQL. Use NTFS instead.

On Linux 2.2, you can get MyISAM tables larger than 2GB in size by using the Large File Support (LFS) patch for the ext2 filesystem. Most current Linux distributions are based on kernel 2.4 or higher and include all the required LFS patches. On Linux 2.4, patches also exist for ReiserFS to get support for big files (up to 2TB). With JFS and XFS, petabyte and larger files are possible on Linux.

For a detailed overview about LFS in Linux, have a look at Andreas Jaeger's Large File Support in Linux page at http://www.suse.de/~aj/linux_lfs.html.

If you do encounter a full-table error, there are several reasons why it might have occurred:

You are using a MySQL server older than 3.23 and an in-memory temporary table becomes larger than tmp_table_size bytes. To avoid this problem, you can use the --tmp_table_size=val option to make mysqld increase the temporary table size or use the SQL option SQL_BIG_TABLES before you issue the problematic query. See 「SET 構文」.
You can also start mysqld with the --big-tables option. This is exactly the same as using SQL_BIG_TABLES for all queries.
As of MySQL 3.23, this problem should not occur. If an in-memory temporary table becomes larger than tmp_table_size, the server automatically converts it to a disk-based MyISAM table.
The InnoDB storage engine maintains InnoDB tables within a tablespace that can be created from several files. This allows a table to exceed the maximum individual file size. The tablespace can include raw disk partitions, which allows extremely large tables. The maximum tablespace size is 64TB.
If you are using InnoDB tables and run out of room in the InnoDB tablespace. In this case, the solution is to extend the InnoDB tablespace. See 「InnoDB データとログファイルの追加と削除」.
You are using MyISAM tables on an operating system that supports files only up to 2GB in size and you have hit this limit for the data file or index file.
You are using a MyISAM table and the space required for the table exceeds what is allowed by the internal pointer size. MyISAM creates tables to allow up to 256GB by default, but this limit can be changed up to the maximum allowable size of 65,536TB (256⁷ – 1 bytes).
If you need a MyISAM table that is larger than the default limit and your operating system supports large files, the CREATE TABLE statement supports AVG_ROW_LENGTH and MAX_ROWS options. See 「CREATE TABLE 構文」. The server uses these options to determine how large a table to allow.
If the pointer size is too small for an existing table, you can change the options with ALTER TABLE to increase a table's maximum allowable size. See 「ALTER TABLE 構文」.
```
ALTER TABLE tbl_name MAX_ROWS=1000000000 AVG_ROW_LENGTH=nnn;
```
You have to specify AVG_ROW_LENGTH only for tables with BLOB or TEXT columns; in this case, MySQL can't optimize the space required based only on the number of rows.
To change the default size limit for MyISAM tables, set the myisam_data_pointer_size, which sets the number of bytes used for internal row pointers. The value is used to set the pointer size for new tables if you do not specify the MAX_ROWS option. The value of myisam_data_pointer_size can be from 2 to 7. A value of 4 allows tables up to 4GB; a value of 6 allows tables up to 256TB.
You can check the maximum data and index sizes by using this statement:
```
SHOW TABLE STATUS FROM db_name LIKE 'tbl_name';
```
You also can use myisamchk -dv /path/to/table-index-file. See 「SHOW 構文」, or 「myisamchk — MyISAM テーブルメンテナンスユーティリティ」.
Other ways to work around file-size limits for MyISAM tables are as follows:
- If your large table is read-only, you can use myisampack to compress it. myisampack usually compresses a table by at least 50%, so you can have, in effect, much bigger tables. myisampack also can merge multiple tables into a single table. See 「myisampack — 圧縮された、読み取り専用MyISAM テーブルを作成する。」.
- MySQL includes a MERGE library that allows you to handle a collection of MyISAM tables that have identical structure as a single MERGE table. See 「MERGE ストレージエンジン」.
You are using the NDB storage engine, in which case you need to increase the values for the DataMemory and IndexMemory configuration parameters in your config.ini file. See 「データノードの設定パラメータ」.
You are using the MEMORY (HEAP) storage engine; in this case you need to increase the value of the max_heap_table_size system variable. See 「システム変数」.

B.1.2.12. `Can't create/write to file`

If you get an error of the following type for some queries, it means that MySQL cannot create a temporary file for the result set in the temporary directory:

Can't create/write to file '\\sqla3fe_0.ism'.

The preceding error is a typical message for Windows; the Unix message is similar.

One fix is to start mysqld with the --tmpdir option or to add the option to the [mysqld] section of your option file. For example, to specify a directory of C:\temp, use these lines:

[mysqld]
tmpdir=C:/temp

The C:\temp directory must exist and have sufficient space for the MySQL server to write to. See 「オプションファイルの使用」.

Another cause of this error can be permissions issues. Make sure that the MySQL server can write to the tmpdir directory.

Check also the error code that you get with perror. One reason the server cannot write to a table is that the filesystem is full:

shell> perror 28
Error code  28:  No space left on device

B.1.2.13. `Commands out of sync`

If you get Commands out of sync; you can't run this command now in your client code, you are calling client functions in the wrong order.

This can happen, for example, if you are using mysql_use_result() and try to execute a new query before you have called mysql_free_result(). It can also happen if you try to execute two queries that return data without calling mysql_use_result() or mysql_store_result() in between.

B.1.2.14. `Ignoring user`

If you get the following error, it means that when mysqld was started or when it reloaded the grant tables, it found an account in the user table that had an invalid password.

Found wrong password for user 'some_user'@'some_host'; ignoring user

As a result, the account is simply ignored by the permission system.

The following list indicates possible causes of and fixes for this problem:

You may be running a new version of mysqld with an old user table. You can check this by executing mysqlshow mysql user to see whether the Password column is shorter than 16 characters. If so, you can correct this condition by running the scripts/add_long_password script.
The account has an old password (eight characters long) and you didn't start mysqld with the --old-protocol option. Update the account in the user table to have a new password or restart mysqld with the --old-protocol option.
You have specified a password in the user table without using the PASSWORD() function. Use mysql to update the account in the user table with a new password, making sure to use the PASSWORD() function:
```
mysql> UPDATE user SET Password=PASSWORD('newpwd')
    -> WHERE User='some_user' AND Host='some_host';
```

B.1.2.15. `Table 'tbl_name' doesn't exist`

If you get either of the following errors, it usually means that no table exists in the default database with the given name:

Table 'tbl_name' doesn't exist
Can't find file: 'tbl_name' (errno: 2)

In some cases, it may be that the table does exist but that you are referring to it incorrectly:

Because MySQL uses directories and files to store databases and tables, database and table names are case sensitive if they are located on a filesystem that has case-sensitive filenames.
Even for filesystems that are not case sensitive, such as on Windows, all references to a given table within a query must use the same lettercase.

You can check which tables are in the default database with SHOW TABLES. See 「SHOW 構文」.

B.1.2.16. `Can't initialize character set`

You might see an error like this if you have character set problems:

MySQL Connection Failed: Can't initialize character set charset_name

This error can have any of the following causes:

The character set is a multi-byte character set and you have no support for the character set in the client. In this case, you need to recompile the client by running configure with the --with-charset=charset_name or --with-extra-charsets=charset_name option. See 「典型的な configure オプション」.
All standard MySQL binaries are compiled with --with-extra-character-sets=complex, which enables support for all multi-byte character sets. See 「データおよびソート用キャラクタセット」.
The character set is a simple character set that is not compiled into mysqld, and the character set definition files are not in the place where the client expects to find them.
In this case, you need to use one of the following methods to solve the problem:
- Recompile the client with support for the character set. See 「典型的な configure オプション」.
- Specify to the client the directory where the character set definition files are located. For many clients, you can do this with the --character-sets-dir option.
- Copy the character definition files to the path where the client expects them to be.

B.1.2.17. '`File`' Not Found and Similar Errors

If you get ERROR '...' not found (errno: 23), Can't open file: ... (errno: 24), or any other error with errno 23 or errno 24 from MySQL, it means that you haven't allocated enough file descriptors for the MySQL server. You can use the perror utility to get a description of what the error number means:

shell> perror 23
Error code  23:  File table overflow
shell> perror 24
Error code  24:  Too many open files
shell> perror 11
Error code  11:  Resource temporarily unavailable

The problem here is that mysqld is trying to keep open too many files simultaneously. You can either tell mysqld not to open so many files at once or increase the number of file descriptors available to mysqld.

To tell mysqld to keep open fewer files at a time, you can make the table cache smaller by reducing the value of the table_open_cache system variable (the default value is 64). Reducing the value of max_connections also reduces the number of open files (the default value is 100).

To change the number of file descriptors available to mysqld, you can use the --open-files-limit option to mysqld_safe or (as of MySQL 3.23.30) set the open_files_limit system variable. See 「システム変数」. The easiest way to set these values is to add an option to your option file. See 「オプションファイルの使用」. If you have an old version of mysqld that doesn't support setting the open files limit, you can edit the mysqld_safe script. There is a commented-out line ulimit -n 256 in the script. You can remove the ‘#’ character to uncomment this line, and change the number 256 to set the number of file descriptors to be made available to mysqld.

--open-files-limit and ulimit can increase the number of file descriptors, but only up to the limit imposed by the operating system. There is also a 「hard」 limit that can be overridden only if you start mysqld_safe or mysqld as root (just remember that you also need to start the server with the --user option in this case so that it does not continue to run as root after it starts up). If you need to increase the operating system limit on the number of file descriptors available to each process, consult the documentation for your system.

Note: If you run the tcsh shell, ulimit does not work! tcsh also reports incorrect values when you ask for the current limits. In this case, you should start mysqld_safe using sh.

B.1.3.2. Problems with File Permissions

B.1.3.1. Problems Linking to the MySQL Client Library

When you are linking an application program to use the MySQL client library, you might get undefined reference errors for symbols that start with mysql_, such as those shown here:

/tmp/ccFKsdPa.o: In function `main':
/tmp/ccFKsdPa.o(.text+0xb): undefined reference to `mysql_init'
/tmp/ccFKsdPa.o(.text+0x31): undefined reference to `mysql_real_connect'
/tmp/ccFKsdPa.o(.text+0x57): undefined reference to `mysql_real_connect'
/tmp/ccFKsdPa.o(.text+0x69): undefined reference to `mysql_error'
/tmp/ccFKsdPa.o(.text+0x9a): undefined reference to `mysql_close'

You should be able to solve this problem by adding -Ldir_path -lmysqlclient at the end of your link command, where dir_path represents the pathname of the directory where the client library is located. To determine the correct directory, try this command:

shell> mysql_config --libs

The output from mysql_config might indicate other libraries that should be specified on the link command as well.

If you get undefined reference errors for the uncompress or compress function, add -lz to the end of your link command and try again.

If you get undefined reference errors for a function that should exist on your system, such as connect, check the manual page for the function in question to determine which libraries you should add to the link command.

You might get undefined reference errors such as the following for functions that don't exist on your system:

mf_format.o(.text+0x201): undefined reference to `__lxstat'

This usually means that your MySQL client library was compiled on a system that is not 100% compatible with yours. In this case, you should download the latest MySQL source distribution and compile MySQL yourself. See 「ソースのディストリビューションを使用した MySQL のインストール」.

You might get undefined reference errors at runtime when you try to execute a MySQL program. If these errors specify symbols that start with mysql_ or indicate that the mysqlclient library can't be found, it means that your system can't find the shared libmysqlclient.so library. The fix for this is to tell your system to search for shared libraries where the library is located. Use whichever of the following methods is appropriate for your system:

Add the path to the directory where libmysqlclient.so is located to the LD_LIBRARY_PATH environment variable.
Add the path to the directory where libmysqlclient.so is located to the LD_LIBRARY environment variable.
Copy libmysqlclient.so to some directory that is searched by your system, such as /lib, and update the shared library information by executing ldconfig.

Another way to solve this problem is by linking your program statically with the -static option, or by removing the dynamic MySQL libraries before linking your code. Before trying the second method, you should be sure that no other programs are using the dynamic libraries.

B.1.3.2. Problems with File Permissions

If you have problems with file permissions, the UMASK environment variable might be set incorrectly when mysqld starts. For example, MySQL might issue the following error message when you create a table:

ERROR: Can't find file: 'path/with/filename.frm' (Errcode: 13)

The default UMASK value is 0660. You can change this behavior by starting mysqld_safe as follows:

shell> UMASK=384  # = 600 in octal
shell> export UMASK
shell> mysqld_safe &

By default, MySQL creates database directories with an access permission value of 0700. You can modify this behavior by setting the UMASK_DIR variable. If you set its value, new directories are created with the combined UMASK and UMASK_DIR values. For example, if you want to give group access to all new directories, you can do this:

shell> UMASK_DIR=504  # = 770 in octal
shell> export UMASK_DIR
shell> mysqld_safe &

In MySQL 3.23.25 and above, MySQL assumes that the value for UMASK and UMASK_DIR is in octal if it starts with a zero.

See 「環境変数」.

B.1.4.1. How to Reset the Root Password

If you have never set a root password for MySQL, the server does not require a password at all for connecting as root. However, it is recommended to set a password for each account. See 「セキュリティガイドライン」.

If you set a root password previously, but have forgotten what it was, you can set a new password. The following procedure is for Windows systems. The procedure for Unix systems is given later in this section.

The procedure under Windows:

Log on to your system as Administrator.
Stop the MySQL server if it is running. For a server that is running as a Windows service, go to the Services manager:
```
Start Menu -> Control Panel -> Administrative Tools -> Services
```
Then find the MySQL service in the list, and stop it.
If your server is not running as a service, you may need to use the Task Manager to force it to stop.
Create a text file and place the following command within it on a single line:
```
SET PASSWORD FOR 'root'@'localhost' = PASSWORD('MyNewPassword');
```
Save the file with any name. For this example the file will be C:\mysql-init.txt.
Open a console window to get to the DOS command prompt:
```
Start Menu -> Run -> cmd
```
We are assuming that you installed MySQL to C:\mysql. If you installed MySQL to another location, adjust the following commands accordingly.
At the DOS command prompt, execute this command:
```
C:\> C:\mysql\bin\mysqld-nt --init-file=C:\mysql-init.txt
```
The contents of the file named by the --init-file option are executed at server startup, changing the root password. After the server has started successfully, you should delete C:\mysql-init.txt.
If you install MySQL using the MySQL Installation Wizard, you may need to specify a --defaults-file option:
```
C:\> "C:\Program Files\MySQL\MySQL Server 5.1\bin\mysqld-nt.exe"
         --defaults-file="C:\Program Files\MySQL\MySQL Server 5.1\my.ini"
         --init-file=C:\mysql-init.txt
```
The appropriate --defaults-file setting can be found using the Services Manager:
```
Start Menu -> Control Panel -> Administrative Tools -> Services
```
Find the MySQL service in the list, right-click on it, and choose the Properties option. The Path to executable field contains the --defaults-file setting.
Stop the MySQL server, then restart it in normal mode again. If you run the server as a service, start it from the Windows Services window. If you start the server manually, use whatever command you normally use.
You should be able to connect using the new password.

In a Unix environment, the procedure for resetting the root password is as follows:

Log on to your system as either the Unix root user or as the same user that the mysqld server runs as.
Locate the .pid file that contains the server's process ID. The exact location and name of this file depend on your distribution, hostname, and configuration. Common locations are /var/lib/mysql/, /var/run/mysqld/, and /usr/local/mysql/data/. Generally, the filename has the extension of .pid and begins with either mysqld or your system's hostname.
You can stop the MySQL server by sending a normal kill (not kill -9) to the mysqld process, using the pathname of the .pid file in the following command:
```
shell> kill `cat /mysql-data-directory/host_name.pid`
```
Note the use of backticks rather than forward quotes with the cat command; these cause the output of cat to be substituted into the kill command.
Create a text file and place the following command within it on a single line:
```
SET PASSWORD FOR 'root'@'localhost' = PASSWORD('MyNewPassword');
```
Save the file with any name. For this example the file will be ~/mysql-init.
Restart the MySQL server with the special --init-file=~/mysql-init option:
```
shell> mysqld_safe --init-file=~/mysql-init &
```
The contents of the init-file are executed at server startup, changing the root password. After the server has started successfully you should delete ~/mysql-init.
You should be able to connect using the new password.

Alternatively, on any platform, you can set the new password using the mysql client(but this approach is less secure):

Stop mysqld and restart it with the --skip-grant-tables --user=root options (Windows users omit the --user=root portion).
Connect to the mysqld server with this command:
```
shell> mysql -u root
```

Issue the following statements in the mysql client:

mysql> UPDATE mysql.user SET Password=PASSWORD('newpwd')
    ->                   WHERE User='root';
mysql> FLUSH PRIVILEGES;

Replace 「newpwd」 with the actual root password that you want to use.

You should be able to connect using the new password.

B.1.4.2. What to Do If MySQL Keeps Crashing

Each MySQL version is tested on many platforms before it is released. This doesn't mean that there are no bugs in MySQL, but if there are bugs, they should be very few and can be hard to find. If you have a problem, it always helps if you try to find out exactly what crashes your system, because you have a much better chance of getting the problem fixed quickly.

First, you should try to find out whether the problem is that the mysqld server dies or whether your problem has to do with your client. You can check how long your mysqld server has been up by executing mysqladmin version. If mysqld has died and restarted, you may find the reason by looking in the server's error log. See 「エラーログ」.

On some systems, you can find in the error log a stack trace of where mysqld died that you can resolve with the resolve_stack_dump program. See Using a Stack Trace. Note that the variable values written in the error log may not always be 100% correct.

Many server crashes are caused by corrupted data files or index files. MySQL updates the files on disk with the write() system call after every SQL statement and before the client is notified about the result. (This is not true if you are running with --delay-key-write, in which case data files are written but not index files.) This means that data file contents are safe even if mysqld crashes, because the operating system ensures that the unflushed data is written to disk. You can force MySQL to flush everything to disk after every SQL statement by starting mysqld with the --flush option.

The preceding means that normally you should not get corrupted tables unless one of the following happens:

The MySQL server or the server host was killed in the middle of an update.
You have found a bug in mysqld that caused it to die in the middle of an update.
Some external program is manipulating data files or index files at the same time as mysqld without locking the table properly.
You are running many mysqld servers using the same data directory on a system that doesn't support good filesystem locks (normally handled by the lockd lock manager), or you are running multiple servers with external locking disabled.
You have a crashed data file or index file that contains very corrupt data that confused mysqld.
You have found a bug in the data storage code. This isn't likely, but it's at least possible. In this case, you can try to change the storage engine to another engine by using ALTER TABLE on a repaired copy of the table.

Because it is very difficult to know why something is crashing, first try to check whether things that work for others crash for you. Please try the following things:

Stop the mysqld server with mysqladmin shutdown, run myisamchk --silent --force */*.MYI from the data directory to check all MyISAM tables, and restart mysqld. This ensures that you are running from a clean state. See 4章データベース管理.
Start mysqld with the --log option and try to determine from the information written to the log whether some specific query kills the server. About 95% of all bugs are related to a particular query. Normally, this is one of the last queries in the log file just before the server restarts. See 「一般クエリログ」. If you can repeatedly kill MySQL with a specific query, even when you have checked all tables just before issuing it, then you have been able to locate the bug and should submit a bug report for it. See 「質問またはバグの報告」.
Try to make a test case that we can use to repeat the problem. See Making a Test Case If You Experience Table Corruption.
Try running the tests in the mysql-test directory and the MySQL benchmarks. See 「MySQL Test Suite」. They should test MySQL rather well. You can also add code to the benchmarks that simulates your application. The benchmarks can be found in the sql-bench directory in a source distribution or, for a binary distribution, in the sql-bench directory under your MySQL installation directory.
Try the fork_big.pl script. (It is located in the tests directory of source distributions.)
If you configure MySQL for debugging, it is much easier to gather information about possible errors if something goes wrong. Configuring MySQL for debugging causes a safe memory allocator to be included that can find some errors. It also provides a lot of output about what is happening. Reconfigure MySQL with the --with-debug or --with-debug=full option to configure and then recompile. See Debugging a MySQL Server.
Make sure that you have applied the latest patches for your operating system.
Use the --skip-external-locking option to mysqld. On some systems, the lockd lock manager does not work properly; the --skip-external-locking option tells mysqld not to use external locking. (This means that you cannot run two mysqld servers on the same data directory and that you must be careful if you use myisamchk. Nevertheless, it may be instructive to try the option as a test.)
Have you tried mysqladmin -u root processlist when mysqld appears to be running but not responding? Sometimes mysqld is not comatose even though you might think so. The problem may be that all connections are in use, or there may be some internal lock problem. mysqladmin -u root processlist usually is able to make a connection even in these cases, and can provide useful information about the current number of connections and their status.
Run the command mysqladmin -i 5 status or mysqladmin -i 5 -r status in a separate window to produce statistics while you run your other queries.
Try the following:
1. Start mysqld from gdb (or another debugger). See Debugging mysqld under gdb.
2. Run your test scripts.
3. Print the backtrace and the local variables at the three lowest levels. In gdb, you can do this with the following commands when mysqld has crashed inside gdb:
```
backtrace
info local
up
info local
up
info local
```
  With gdb, you can also examine which threads exist with info threads and switch to a specific thread with thread N, where N is the thread ID.
Try to simulate your application with a Perl script to force MySQL to crash or misbehave.
Send a normal bug report. See 「質問またはバグの報告」. Be even more detailed than usual. Because MySQL works for many people, it may be that the crash results from something that exists only on your computer (for example, an error that is related to your particular system libraries).
If you have a problem with tables containing dynamic-length rows and you are using only VARCHAR columns (not BLOB or TEXT columns), you can try to change all VARCHAR to CHAR with ALTER TABLE. This forces MySQL to use fixed-size rows. Fixed-size rows take a little extra space, but are much more tolerant to corruption.
The current dynamic row code has been in use at MySQL AB for several years with very few problems, but dynamic-length rows are by nature more prone to errors, so it may be a good idea to try this strategy to see whether it helps.
Do not rule out your server hardware when diagnosing problems. Defective hardware can be the cause of data corruption. Particular attention should be paid to both RAMS and hard-drives when troubleshooting hardware.

B.1.4.3. How MySQL Handles a Full Disk

This section describes how MySQL responds to disk-full errors (such as 「no space left on device」), and to quota-exceeded errors (such as 「write failed」 or 「user block limit reached」).

This section is relevant for writes to MyISAM tables. It also applies for writes to binary log files and binary log index file, except that references to 「row」 and 「record」 should be understood to mean 「event.」

When a disk-full condition occurs, MySQL does the following:

It checks once every minute to see whether there is enough space to write the current row. If there is enough space, it continues as if nothing had happened.
Every 10 minutes it writes an entry to the log file, warning about the disk-full condition.

To alleviate the problem, you can take the following actions:

To continue, you only have to free enough disk space to insert all records.
To abort the thread, you must use mysqladmin kill. The thread is aborted the next time it checks the disk (in one minute).
Other threads might be waiting for the table that caused the disk-full condition. If you have several 「locked」 threads, killing the one thread that is waiting on the disk-full condition allows the other threads to continue.

Exceptions to the preceding behavior are when you use REPAIR TABLE or OPTIMIZE TABLE or when the indexes are created in a batch after LOAD DATA INFILE or after an ALTER TABLE statement. All of these statements may create large temporary files that, if left to themselves, would cause big problems for the rest of the system. If the disk becomes full while MySQL is doing any of these operations, it removes the big temporary files and mark the table as crashed. The exception is that for ALTER TABLE, the old table is left unchanged.

B.1.4.4. Where MySQL Stores Temporary Files

MySQL uses the value of the TMPDIR environment variable as the pathname of the directory in which to store temporary files. If you don't have TMPDIR set, MySQL uses the system default, which is normally /tmp, /var/tmp, or /usr/tmp. If the filesystem containing your temporary file directory is too small, you can use the --tmpdir option to mysqld to specify a directory in a filesystem where you have enough space.

In MySQL 5.1, the --tmpdir option can be set to a list of several paths that are used in round-robin fashion. Paths should be separated by colon characters (‘:’) on Unix and semicolon characters (‘;’) on Windows, NetWare, and OS/2. Note: To spread the load effectively, these paths should be located on different physical disks, not different partitions of the same disk.

If the MySQL server is acting as a replication slave, you should not set --tmpdir to point to a directory on a memory-based filesystem or to a directory that is cleared when the server host restarts. A replication slave needs some of its temporary files to survive a machine restart so that it can replicate temporary tables or LOAD DATA INFILE operations. If files in the temporary file directory are lost when the server restarts, replication fails.

MySQL creates all temporary files as hidden files. This ensures that the temporary files are removed if mysqld is terminated. The disadvantage of using hidden files is that you do not see a big temporary file that fills up the filesystem in which the temporary file directory is located.

MySQL Enterprise Advisors provided by the MySQL Network Monitoring and Advisory Service automatically detect excessive temporary table storage to disk. For more information see, http://www.mysql.com/products/enterprise/advisors.html.

When sorting (ORDER BY or GROUP BY), MySQL normally uses one or two temporary files. The maximum disk space required is determined by the following expression:

(length of what is sorted + sizeof(row pointer))
* number of matched rows
* 2

The row pointer size is usually four bytes, but may grow in the future for really big tables.

For some SELECT queries, MySQL also creates temporary SQL tables. These are not hidden and have names of the form SQL_*.

ALTER TABLE creates a temporary table in the same directory as the original table.

B.1.4.5. How to Protect or Change the MySQL Unix Socket File

The default location for the Unix socket file that the server uses for communication with local clients is /tmp/mysql.sock. (For some distribution formats, the directory might be different, such as /var/lib/mysql for RPMs.)

On some versions of Unix, anyone can delete files in the /tmp directory or other similar directories used for temporary files. If the socket file is located in such a directory on your system, this might cause problems.

On most versions of Unix, you can protect your /tmp directory so that files can be deleted only by their owners or the superuser (root). To do this, set the sticky bit on the /tmp directory by logging in as root and using the following command:

shell> chmod +t /tmp

You can check whether the sticky bit is set by executing ls -ld /tmp. If the last permission character is t, the bit is set.

Another approach is to change the place where the server creates the Unix socket file. If you do this, you should also let client programs know the new location of the file. You can specify the file location in several ways:

Specify the path in a global or local option file. For example, put the following lines in /etc/my.cnf:
```
[mysqld]
socket=/path/to/socket

[client]
socket=/path/to/socket
```
See 「オプションファイルの使用」.
Specify a --socket option on the command line to mysqld_safe and when you run client programs.
Set the MYSQL_UNIX_PORT environment variable to the path of the Unix socket file.
Recompile MySQL from source to use a different default Unix socket file location. Define the path to the file with the --with-unix-socket-path option when you run configure. See 「典型的な configure オプション」.

You can test whether the new socket location works by attempting to connect to the server with this command:

shell> mysqladmin --socket=/path/to/socket version

B.1.4.6. Time Zone Problems

If you have a problem with SELECT NOW() returning values in UTC and not your local time, you have to tell the server your current time zone. The same applies if UNIX_TIMESTAMP() returns the wrong value. This should be done for the environment in which the server runs; for example, in mysqld_safe or mysql.server. See 「環境変数」.

You can set the time zone for the server with the --timezone=timezone_name option to mysqld_safe. You can also set it by setting the TZ environment variable before you start mysqld.

The allowable values for --timezone or TZ are system-dependent. Consult your operating system documentation to see what values are acceptable.

B.1.5.1. Case Sensitivity in Searches

By default, MySQL searches are not case sensitive (although there are some character sets that are never case insensitive, such as czech). This means that if you search with col_name LIKE 'a%', you get all column values that start with A or a. If you want to make this search case sensitive, make sure that one of the operands has a case sensitive or binary collation. For example, if you are comparing a column and a string that both have the latin1 character set, you can use the COLLATE operator to cause either operand to have the latin1_general_cs or latin1_bin collation. For example:

col_name COLLATE latin1_general_cs LIKE 'a%'
col_name LIKE 'a%' COLLATE latin1_general_cs
col_name COLLATE latin1_bin LIKE 'a%'
col_name LIKE 'a%' COLLATE latin1_bin

If you want a column always to be treated in case-sensitive fashion, declare it with a case sensitive or binary collation. See 「CREATE TABLE 構文」.

Simple comparison operations (>=, >, =, <, <=, sorting, and grouping) are based on each character's 「sort value.」 Characters with the same sort value (such as ‘E’, ‘e’, and ‘ÃÂ©’) are treated as the same character.

B.1.5.2. Problems Using `DATE` Columns

The format of a DATE value is 'YYYY-MM-DD'. According to standard SQL, no other format is allowed. You should use this format in UPDATE expressions and in the WHERE clause of SELECT statements. For example:

mysql> SELECT * FROM tbl_name WHERE date >= '2003-05-05';

As a convenience, MySQL automatically converts a date to a number if the date is used in a numeric context (and vice versa). It is also smart enough to allow a 「relaxed」 string form when updating and in a WHERE clause that compares a date to a TIMESTAMP, DATE, or DATETIME column. (「Relaxed form」 means that any punctuation character may be used as the separator between parts. For example, '2004-08-15' and '2004#08#15' are equivalent.) MySQL can also convert a string containing no separators (such as '20040815'), provided it makes sense as a date.

When you compare a DATE, TIME, DATETIME, or TIMESTAMP to a constant string with the <, <=, =, >=, >, or BETWEEN operators, MySQL normally converts the string to an internal long integer for faster comparison (and also for a bit more 「relaxed」 string checking). However, this conversion is subject to the following exceptions:

When you compare two columns
When you compare a DATE, TIME, DATETIME, or TIMESTAMP column to an expression
When you use any other comparison method than those just listed, such as IN or STRCMP().

For these exceptional cases, the comparison is done by converting the objects to strings and performing a string comparison.

To keep things safe, assume that strings are compared as strings and use the appropriate string functions if you want to compare a temporal value to a string.

The special date '0000-00-00' can be stored and retrieved as '0000-00-00'. When using a '0000-00-00' date through MyODBC, it is automatically converted to NULL in MyODBC 2.50.12 and above, because ODBC can't handle this kind of date.

Because MySQL performs the conversions described above, the following statements work:

mysql> INSERT INTO tbl_name (idate) VALUES (19970505);
mysql> INSERT INTO tbl_name (idate) VALUES ('19970505');
mysql> INSERT INTO tbl_name (idate) VALUES ('97-05-05');
mysql> INSERT INTO tbl_name (idate) VALUES ('1997.05.05');
mysql> INSERT INTO tbl_name (idate) VALUES ('1997 05 05');
mysql> INSERT INTO tbl_name (idate) VALUES ('0000-00-00');

mysql> SELECT idate FROM tbl_name WHERE idate >= '1997-05-05';
mysql> SELECT idate FROM tbl_name WHERE idate >= 19970505;
mysql> SELECT MOD(idate,100) FROM tbl_name WHERE idate >= 19970505;
mysql> SELECT idate FROM tbl_name WHERE idate >= '19970505';

However, the following does not work:

mysql> SELECT idate FROM tbl_name WHERE STRCMP(idate,'20030505')=0;

STRCMP() is a string function, so it converts idate to a string in 'YYYY-MM-DD' format and performs a string comparison. It does not convert '20030505' to the date '2003-05-05' and perform a date comparison.

If you are using the ALLOW_INVALID_DATES SQL mode, MySQL allows you to store dates that are given only limited checking: MySQL requires only that the day is in the range from 1 to 31 and the month is in the range from 1 to 12.

This makes MySQL very convenient for Web applications where you obtain year, month, and day in three different fields and you want to store exactly what the user inserted (without date validation).

If you are not using the NO_ZERO_IN_DATE SQL mode, the day or month part can be zero. This is convenient if you want to store a birthdate in a DATE column and you know only part of the date.

If you are not using the NO_ZERO_DATE SQL mode, MySQL also allows you to store '0000-00-00' as a 「dummy date.」 This is in some cases more convenient than using NULL values.

If the date cannot be converted to any reasonable value, a 0 is stored in the DATE column, which is retrieved as '0000-00-00'. This is both a speed and a convenience issue. We believe that the database server's responsibility is to retrieve the same date you stored (even if the data was not logically correct in all cases). We think it is up to the application and not the server to check the dates.

If you want MySQL to check all dates and accept only legal dates (unless overridden by IGNORE), you should set sql_mode to "NO_ZERO_IN_DATE,NO_ZERO_DATE".

B.1.5.3. Problems with `NULL` Values

The concept of the NULL value is a common source of confusion for newcomers to SQL, who often think that NULL is the same thing as an empty string ''. This is not the case. For example, the following statements are completely different:

mysql> INSERT INTO my_table (phone) VALUES (NULL);
mysql> INSERT INTO my_table (phone) VALUES ('');

Both statements insert a value into the phone column, but the first inserts a NULL value and the second inserts an empty string. The meaning of the first can be regarded as 「phone number is not known」 and the meaning of the second can be regarded as 「the person is known to have no phone, and thus no phone number.」

To help with NULL handling, you can use the IS NULL and IS NOT NULL operators and the IFNULL() function.

In SQL, the NULL value is never true in comparison to any other value, even NULL. An expression that contains NULL always produces a NULL value unless otherwise indicated in the documentation for the operators and functions involved in the expression. All columns in the following example return NULL:

mysql> SELECT NULL, 1+NULL, CONCAT('Invisible',NULL);

If you want to search for column values that are NULL, you cannot use an expr = NULL test. The following statement returns no rows, because expr = NULL is never true for any expression:

mysql> SELECT * FROM my_table WHERE phone = NULL;

To look for NULL values, you must use the IS NULL test. The following statements show how to find the NULL phone number and the empty phone number:

mysql> SELECT * FROM my_table WHERE phone IS NULL;
mysql> SELECT * FROM my_table WHERE phone = '';

See Working with NULL Values, for additional information and examples.

You can add an index on a column that can have NULL values if you are using the MyISAM, InnoDB, or MEMORY storage engine. Otherwise, you must declare an indexed column NOT NULL, and you cannot insert NULL into the column.

When reading data with LOAD DATA INFILE, empty or missing columns are updated with ''. If you want a NULL value in a column, you should use \N in the data file. The literal word 「NULL」 may also be used under some circumstances. See 「LOAD DATA INFILE 構文」.

When using DISTINCT, GROUP BY, or ORDER BY, all NULL values are regarded as equal.

When using ORDER BY, NULL values are presented first, or last if you specify DESC to sort in descending order.

Aggregate (summary) functions such as COUNT(), MIN(), and SUM() ignore NULL values. The exception to this is COUNT(*), which counts rows and not individual column values. For example, the following statement produces two counts. The first is a count of the number of rows in the table, and the second is a count of the number of non-NULL values in the age column:

mysql> SELECT COUNT(*), COUNT(age) FROM person;

For some data types, MySQL handles NULL values specially. If you insert NULL into a TIMESTAMP column, the current date and time is inserted. If you insert NULL into an integer column that has the AUTO_INCREMENT attribute, the next number in the sequence is inserted.

B.1.5.4. Problems with Column Aliases

You can use an alias to refer to a column in GROUP BY, ORDER BY, or HAVING clauses. Aliases can also be used to give columns better names:

SELECT SQRT(a*b) AS root FROM tbl_name GROUP BY root HAVING root > 0;
SELECT id, COUNT(*) AS cnt FROM tbl_name GROUP BY id HAVING cnt > 0;
SELECT id AS 'Customer identity' FROM tbl_name;

Standard SQL doesn't allow you to refer to a column alias in a WHERE clause. This restriction is imposed because when the WHERE code is executed, the column value may not yet be determined. For example, the following query is illegal:

SELECT id, COUNT(*) AS cnt FROM tbl_name WHERE cnt > 0 GROUP BY id;

The WHERE statement is executed to determine which rows should be included in the GROUP BY part, whereas HAVING is used to decide which rows from the result set should be used.

B.1.5.5. Rollback Failure for Non-Transactional Tables

If you receive the following message when trying to perform a ROLLBACK, it means that one or more of the tables you used in the transaction do not support transactions:

Warning: Some non-transactional changed tables couldn't be rolled back

These non-transactional tables are not affected by the ROLLBACK statement.

If you were not deliberately mixing transactional and non-transactional tables within the transaction, the most likely cause for this message is that a table you thought was transactional actually is not. This can happen if you try to create a table using a transactional storage engine that is not supported by your mysqld server (or that was disabled with a startup option). If mysqld doesn't support a storage engine, it instead creates the table as a MyISAM table, which is non-transactional.

You can check the storage engine for a table by using either of these statements:

SHOW TABLE STATUS LIKE 'tbl_name';
SHOW CREATE TABLE tbl_name;

See 「SHOW TABLE STATUS 構文」, and 「SHOW CREATE TABLE 構文」.

You can check which storage engines your mysqld server supports by using this statement:

SHOW ENGINES;

You can also use the following statement, and check the value of the variable that is associated with the storage engine in which you are interested:

SHOW VARIABLES LIKE 'have_%';

For example, to determine whether the InnoDB storage engine is available, check the value of the have_innodb variable.

See 「SHOW ENGINES 構文」, and 「SHOW VARIABLES 構文」.

B.1.5.6. Deleting Rows from Related Tables

If the total length of the DELETE statement for related_table is more than 1MB (the default value of the max_allowed_packet system variable), you should split it into smaller parts and execute multiple DELETE statements. You probably get the fastest DELETE by specifying only 100 to 1,000 related_column values per statement if the related_column is indexed. If the related_column isn't indexed, the speed is independent of the number of arguments in the IN clause.

B.1.5.7. Solving Problems with No Matching Rows

If you have a complicated query that uses many tables but that doesn't return any rows, you should use the following procedure to find out what is wrong:

Test the query with EXPLAIN to check whether you can find something that is obviously wrong. See 「EXPLAINを使用して、クエリを最適化する」.
Select only those columns that are used in the WHERE clause.
Remove one table at a time from the query until it returns some rows. If the tables are large, it's a good idea to use LIMIT 10 with the query.
Issue a SELECT for the column that should have matched a row against the table that was last removed from the query.
If you are comparing FLOAT or DOUBLE columns with numbers that have decimals, you can't use equality (=) comparisons. This problem is common in most computer languages because not all floating-point values can be stored with exact precision. In some cases, changing the FLOAT to a DOUBLE fixes this. See 「Problems with Floating-Point Comparisons」.
If you still can't figure out what's wrong, create a minimal test that can be run with mysql test < query.sql that shows your problems. You can create a test file by dumping the tables with mysqldump --quick db_name tbl_name_1 ... tbl_name_n > query.sql. Open the file in an editor, remove some insert lines (if there are more than needed to demonstrate the problem), and add your SELECT statement at the end of the file.
Verify that the test file demonstrates the problem by executing these commands:
```
shell> mysqladmin create test2
shell> mysql test2 < query.sql
```
Attach the test file to a bug report, which you can file using the instructions in 「質問またはバグの報告」.

B.1.5.8. Problems with Floating-Point Comparisons

Floating-point numbers sometimes cause confusion because they are approximate. That is, they are not stored as exact values inside computer architecture. What you can see on the screen usually is not the exact value of the number. The FLOAT and DOUBLE data types are such. For DECIMAL columns, MySQL performs operations with a precision of 64 decimal digits, which should solve most common inaccuracy problems.

The following example demonstrates the problem using DOUBLE. It shows that are calculations that are done using floating-point operations are subject to floating-point error.

mysql> CREATE TABLE t1 (i INT, d1 DOUBLE, d2 DOUBLE);
mysql> INSERT INTO t1 VALUES (1, 101.40, 21.40), (1, -80.00, 0.00),
    -> (2, 0.00, 0.00), (2, -13.20, 0.00), (2, 59.60, 46.40),
    -> (2, 30.40, 30.40), (3, 37.00, 7.40), (3, -29.60, 0.00),
    -> (4, 60.00, 15.40), (4, -10.60, 0.00), (4, -34.00, 0.00),
    -> (5, 33.00, 0.00), (5, -25.80, 0.00), (5, 0.00, 7.20),
    -> (6, 0.00, 0.00), (6, -51.40, 0.00);

mysql> SELECT i, SUM(d1) AS a, SUM(d2) AS b
    -> FROM t1 GROUP BY i HAVING a <> b;

+------+-------+------+
| i    | a     | b    |
+------+-------+------+
|    1 |  21.4 | 21.4 |
|    2 |  76.8 | 76.8 |
|    3 |   7.4 |  7.4 |
|    4 |  15.4 | 15.4 |
|    5 |   7.2 |  7.2 |
|    6 | -51.4 |    0 |
+------+-------+------+

The result is correct. Although the first five records look like they should not satisfy the comparison (the values of a and b do not appear to be different), they may do so because the difference between the numbers shows up around the tenth decimal or so, depending on factors such as computer architecture or the compiler version or optimization level. For example, different CPUs may evaluate floating-point numbers differently.

If columns d1 and d2 had been defined as DECIMAL rather than DOUBLE, the result of the SELECT query would have contained only one row — the last one shown above.

The correct way to do floating-point number comparison is to first decide on an acceptable tolerance for differences between the numbers and then do the comparison against the tolerance value. For example, if we agree that floating-point numbers should be regarded the same if they are same within a precision of one in ten thousand (0.0001), the comparison should be written to find differences larger than the tolerance value:

mysql> SELECT i, SUM(d1) AS a, SUM(d2) AS b FROM t1
    -> GROUP BY i HAVING ABS(a - b) > 0.0001;
+------+-------+------+
| i    | a     | b    |
+------+-------+------+
|    6 | -51.4 |    0 | 
+------+-------+------+
1 row in set (0.00 sec)

Conversely, to get rows where the numbers are the same, the test should find differences within the tolerance value:

mysql> SELECT i, SUM(d1) AS a, SUM(d2) AS b FROM t1
    -> GROUP BY i HAVING ABS(a - b) <= 0.0001;
+------+------+------+
| i    | a    | b    |
+------+------+------+
|    1 | 21.4 | 21.4 | 
|    2 | 76.8 | 76.8 | 
|    3 |  7.4 |  7.4 | 
|    4 | 15.4 | 15.4 | 
|    5 |  7.2 |  7.2 | 
+------+------+------+
5 rows in set (0.03 sec)

B.1.6. Optimizer-Related Issues

MySQL uses a cost-based optimizer to determine the best way to resolve a query. In many cases, MySQL can calculate the best possible query plan, but sometimes MySQL doesn't have enough information about the data at hand and has to make 「educated」 guesses about the data.

For the cases when MySQL does not do the "right" thing, tools that you have available to help MySQL are:

Use the EXPLAIN statement to get information about how MySQL processes a query. To use it, just add the keyword EXPLAIN to the front of your SELECT statement:
```
mysql> EXPLAIN SELECT * FROM t1, t2 WHERE t1.i = t2.i;
```
EXPLAIN is discussed in more detail in 「EXPLAINを使用して、クエリを最適化する」.
Use ANALYZE TABLE tbl_name to update the key distributions for the scanned table. See 「ANALYZE TABLE 構文」.
Use FORCE INDEX for the scanned table to tell MySQL that table scans are very expensive compared to using the given index. See 「SELECT 構文」.
```
SELECT * FROM t1, t2 FORCE INDEX (index_for_column)
WHERE t1.col_name=t2.col_name;
```
USE INDEX and IGNORE INDEX may also be useful.
Global and table-level STRAIGHT_JOIN. See 「SELECT 構文」.
You can tune global or thread-specific system variables. For example, Start mysqld with the --max-seeks-for-key=1000 option or use SET max_seeks_for_key=1000 to tell the optimizer to assume that no key scan causes more than 1,000 key seeks. See 「システム変数」.

B.1.7. Table Definition-Related Issues

B.1.7.1. Problems with ALTER TABLE
B.1.7.2. How to Change the Order of Columns in a Table
B.1.7.3. TEMPORARY TABLE Problems

B.1.7.1. Problems with `ALTER TABLE`

ALTER TABLE changes a table to the current character set. If you get a duplicate-key error during ALTER TABLE, the cause is either that the new character sets maps two keys to the same value or that the table is corrupted. In the latter case, you should run REPAIR TABLE on the table.

If ALTER TABLE dies with the following error, the problem may be that MySQL crashed during an earlier ALTER TABLE operation and there is an old table named A-xxx or B-xxx lying around:

Error on rename of './database/name.frm'
to './database/B-xxx.frm' (Errcode: 17)

In this case, go to the MySQL data directory and delete all files that have names starting with A- or B-. (You may want to move them elsewhere instead of deleting them.)

ALTER TABLE works in the following way:

Create a new table named A-xxx with the requested structural changes.
Copy all rows from the original table to A-xxx.
Rename the original table to B-xxx.
Rename A-xxx to your original table name.
Delete B-xxx.

If something goes wrong with the renaming operation, MySQL tries to undo the changes. If something goes seriously wrong (although this shouldn't happen), MySQL may leave the old table as B-xxx. A simple rename of the table files at the system level should get your data back.

If you use ALTER TABLE on a transactional table or if you are using Windows or OS/2, ALTER TABLE unlocks the table if you had done a LOCK TABLE on it. This is done because InnoDB and these operating systems cannot drop a table that is in use.

B.1.7.2. How to Change the Order of Columns in a Table

First, consider whether you really need to change the column order in a table. The whole point of SQL is to abstract the application from the data storage format. You should always specify the order in which you wish to retrieve your data. The first of the following statements returns columns in the order col_name1, col_name2, col_name3, whereas the second returns them in the order col_name1, col_name3, col_name2:

mysql> SELECT col_name1, col_name2, col_name3 FROM tbl_name;
mysql> SELECT col_name1, col_name3, col_name2 FROM tbl_name;

If you decide to change the order of table columns anyway, you can do so as follows:

Create a new table with the columns in the new order.

Execute this statement:

mysql> INSERT INTO new_table
    -> SELECT columns-in-new-order FROM old_table;

Drop or rename old_table.

Rename the new table to the original name:

mysql> ALTER TABLE new_table RENAME old_table;

SELECT * is quite suitable for testing queries. However, in an application, you should never rely on using SELECT * and retrieving the columns based on their position. The order and position in which columns are returned does not remain the same if you add, move, or delete columns. A simple change to your table structure could cause your application to fail.

B.1.7.3. `TEMPORARY TABLE` Problems

The following list indicates limitations on the use of TEMPORARY tables:

A TEMPORARY table can only be of type MEMORY, MyISAM, MERGE, or InnoDB.
Temporary tables are not supported for MySQL Cluster.
You cannot refer to a TEMPORARY table more than once in the same query. For example, the following does not work:
```
mysql> SELECT * FROM temp_table, temp_table AS t2;
ERROR 1137: Can't reopen table: 'temp_table'
```
The SHOW TABLES statement does not list TEMPORARY tables.
You cannot use RENAME to rename a TEMPORARY table. However, you can use ALTER TABLE instead:
```
mysql> ALTER TABLE orig_name RENAME new_name;
```
There are known issues in using temporary tables with replication. See 「レプリケーション機能と既知問題」, for more information.

B.1.8. Known Issues in MySQL

B.1.8.1. Open Issues in MySQL

This section is a list of the known issues in recent versions of MySQL.

For information about platform-specific issues, see the installation and porting instructions in 「オペレーティングシステムに特化した注釈」, and Debugging and Porting MySQL.

B.1.8.1. Open Issues in MySQL

The following problems are known and fixing them is a high priority:

MySQL Cluster fails to recover from an out-of-disk failure when using disk data. (Bug #17614)
If you compare a NULL value to a subquery using ALL/ANY/SOME and the subquery returns an empty result, the comparison might evaluate to the non-standard result of NULL rather than to TRUE or FALSE. This will be fixed in MySQL 5.1.
Subquery optimization for IN is not as effective as for =.
Even if you use lower_case_table_names=2 (which enables MySQL to remember the case used for databases and table names), MySQL does not remember the case used for database names for the function DATABASE() or within the various logs (on case-insensitive systems).
Dropping a FOREIGN KEY constraint doesn't work in replication because the constraint may have another name on the slave.
REPLACE (and LOAD DATA with the REPLACE option) does not trigger ON DELETE CASCADE.
DISTINCT with ORDER BY doesn't work inside GROUP_CONCAT() if you don't use all and only those columns that are in the DISTINCT list.
If one user has a long-running transaction and another user drops a table that is updated in the transaction, there is small chance that the binary log may contain the DROP TABLE command before the table is used in the transaction itself. We plan to fix this by having the DROP TABLE command wait until the table is not being used in any transaction.
When inserting a big integer value (between 2⁶³ and 2⁶⁴–1) into a decimal or string column, it is inserted as a negative value because the number is evaluated in a signed integer context.
FLUSH TABLES WITH READ LOCK does not block COMMIT if the server is running without binary logging, which may cause a problem (of consistency between tables) when doing a full backup.
ANALYZE TABLE, OPTIMIZE TABLE, and REPAIR TABLE may cause problems on tables for which you are using INSERT DELAYED.
Performing LOCK TABLE ... and FLUSH TABLES ... doesn't guarantee that there isn't a half-finished transaction in progress on the table.
Replication uses query-level logging: The master writes the executed queries to the binary log. This is a very fast, compact, and efficient logging method that works perfectly in most cases.
It is possible for the data on the master and slave to become different if a query is designed in such a way that the data modification is non-deterministic (generally not a recommended practice, even outside of replication).
For example:
- CREATE ... SELECT or INSERT ... SELECT statements that insert zero or NULL values into an AUTO_INCREMENT column.
- DELETE if you are deleting rows from a table that has foreign keys with ON DELETE CASCADE properties.
- REPLACE ... SELECT, INSERT IGNORE ... SELECT if you have duplicate key values in the inserted data.
If and only if the preceding queries have no ORDER BY clause guaranteeing a deterministic order.
For example, for INSERT ... SELECT with no ORDER BY, the SELECT may return rows in a different order (which results in a row having different ranks, hence getting a different number in the AUTO_INCREMENT column), depending on the choices made by the optimizers on the master and slave.
A query is optimized differently on the master and slave only if:
- The table is stored using a different storage engine on the master than on the slave. (It is possible to use different storage engines on the master and slave. For example, you can use InnoDB on the master, but MyISAM on the slave if the slave has less available disk space.)
- MySQL buffer sizes (key_buffer_size, and so on) are different on the master and slave.
- The master and slave run different MySQL versions, and the optimizer code differs between these versions.
This problem may also affect database restoration using mysqlbinlog|mysql.
The easiest way to avoid this problem is to add an ORDER BY clause to the aforementioned non-deterministic queries to ensure that the rows are always stored or modified in the same order.
In future MySQL versions, we will automatically add an ORDER BY clause when needed.

The following issues are known and will be fixed in due time:

Log filenames are based on the server hostname (if you don't specify a filename with the startup option). You have to use options such as --log-bin=old_host_name-bin if you change your hostname to something else. Another option is to rename the old files to reflect your hostname change (if these are binary logs, you need to edit the binary log index file and fix the binlog names there as well). See 「コマンドオプション」.
mysqlbinlog does not delete temporary files left after a LOAD DATA INFILE command. See 「mysqlbinlog — バイナリログファイルを処理するためのユーティリティ」.
RENAME doesn't work with TEMPORARY tables or tables used in a MERGE table.
Due to the way table format (.frm) files are stored, you cannot use character 255 (CHAR(255)) in table names, column names, or enumerations. This is scheduled to be fixed in version 5.1 when we implement new table definition format files.
When using SET CHARACTER SET, you can't use translated characters in database, table, and column names.
You can't use ‘_’ or ‘%’ with ESCAPE in LIKE ... ESCAPE.
If you have a DECIMAL column in which the same number is stored in different formats (for example, +01.00, 1.00, 01.00), GROUP BY may regard each value as a different value.
You cannot build the server in another directory when using MIT-pthreads. Because this requires changes to MIT-pthreads, we are not likely to fix this. See 「MIT-pthreads ノート」.
BLOB and TEXT values can't reliably be used in GROUP BY, ORDER BY or DISTINCT. Only the first max_sort_length bytes are used when comparing BLOB values in these cases. The default value of max_sort_length is 1024 and can be changed at server startup time or at runtime.
Numeric calculations are done with BIGINT or DOUBLE (both are normally 64 bits long). Which precision you get depends on the function. The general rule is that bit functions are performed with BIGINT precision, IF and ELT() with BIGINT or DOUBLE precision, and the rest with DOUBLE precision. You should try to avoid using unsigned long long values if they resolve to be larger than 63 bits (9223372036854775807) for anything other than bit fields.
You can have up to 255 ENUM and SET columns in one table.
In MIN(), MAX(), and other aggregate functions, MySQL currently compares ENUM and SET columns by their string value rather than by the string's relative position in the set.
mysqld_safe redirects all messages from mysqld to the mysqld log. One problem with this is that if you execute mysqladmin refresh to close and reopen the log, stdout and stderr are still redirected to the old log. If you use --log extensively, you should edit mysqld_safe to log to host_name.err instead of host_name.log so that you can easily reclaim the space for the old log by deleting it and executing mysqladmin refresh.
In an UPDATE statement, columns are updated from left to right. If you refer to an updated column, you get the updated value instead of the original value. For example, the following statement increments KEY by 2, not 1:
```
mysql> UPDATE tbl_name SET KEY=KEY+1,KEY=KEY+1;
```
You can refer to multiple temporary tables in the same query, but you cannot refer to any given temporary table more than once. For example, the following doesn't work:
```
mysql> SELECT * FROM temp_table, temp_table AS t2;
ERROR 1137: Can't reopen table: 'temp_table'
```
The optimizer may handle DISTINCT differently when you are using 「hidden」 columns in a join than when you are not. In a join, hidden columns are counted as part of the result (even if they are not shown), whereas in normal queries, hidden columns don't participate in the DISTINCT comparison. We will probably change this in the future to never compare the hidden columns when executing DISTINCT.
An example of this is:
```
SELECT DISTINCT mp3id FROM band_downloads
       WHERE userid = 9 ORDER BY id DESC;
```
and
```
SELECT DISTINCT band_downloads.mp3id
       FROM band_downloads,band_mp3
       WHERE band_downloads.userid = 9
       AND band_mp3.id = band_downloads.mp3id
       ORDER BY band_downloads.id DESC;
```
In the second case, using MySQL Server 3.23.x, you may get two identical rows in the result set (because the values in the hidden id column may differ).
Note that this happens only for queries where that do not have the ORDER BY columns in the result.
If you execute a PROCEDURE on a query that returns an empty set, in some cases the PROCEDURE does not transform the columns.
Creation of a table of type MERGE doesn't check whether the underlying tables are compatible types.
If you use ALTER TABLE to add a UNIQUE index to a table used in a MERGE table and then add a normal index on the MERGE table, the key order is different for the tables if there was an old, non-UNIQUE key in the table. This is because ALTER TABLE puts UNIQUE indexes before normal indexes to be able to detect duplicate keys as early as possible.

B.2. Server Error Codes and Messages

MySQL programs have access to several types of error information when the server returns an error. For example, the mysql client program displays errors using the following format:

shell> SELECT * FROM no_such_table;
ERROR 1146 (42S02): Table 'test.no_such_table' doesn't exist

The message displayed contains three types of information:

A numeric error value (1146). This number is MySQL-specific and is not portable to other database systems.
A five-character SQLSTATE value ('42S02'). The values are specified by ANSI SQL and ODBC and are more standardized. Not all MySQL error numbers are mapped to SQLSTATE error codes. The value 'HY000' (general error) is used for unmapped errors.
A string that provides a textual description of the error.

Server error information comes from the following source files. For details about the way that error information is defined, see the MySQL Internals manual, available at http://dev.mysql.com/doc/.

Error message information is listed in the share/errmsg.txt file. %d and %s represent numbers and strings, respectively, that are substituted into the Message values when they are displayed.
The Error values listed in share/errmsg.txt are used to generate the definitions in the include/mysqld_error.h and include/mysqld_ername.h MySQL source files.
The SQLSTATE values listed in share/errmsg.txt are used to generate the definitions in the include/sql_state.h MySQL source file.

Because updates are frequent, it is possible that those files will contain additional error information not listed here.
