MYSQL(1) MySQL Database System MYSQL(1)
NAME
mysql - the MySQL command-line tool
SYNOPSIS
mysql [options] db_name
DESCRIPTION
mysql is a simple SQL shell (with GNU readline capabilities). It supports interactive and
non-interactive use. When used interactively, query results are presented in an ASCII-table format.
When used non-interactively (for example, as a filter), the result is presented in tab-separated
format. The output format can be changed using command options.
If you have problems due to insufficient memory for large result sets, use the --quick option. This
forces mysql to retrieve results from the server a row at a time rather than retrieving the entire
result set and buffering it in memory before displaying it. This is done by returning the result set
using the mysql_use_result() C API function in the client/server library rather than
mysql_store_result().
Using mysql is very easy. Invoke it from the prompt of your command interpreter as follows:
shell> mysql db_name
Or:
shell> mysql --user=user_name --password=your_password db_name
Then type an SQL statement, end it with `;', \g, or \G and press Enter.
As of MySQL 5.0.25, typing Control-C causes mysql to attempt to kill the current statement. If this
cannot be done, or Control-C is typed again before the statement is killed, mysql exits. Previously,
Control-C caused mysql to exit in all cases.
You can execute SQL statements in a script file (batch file) like this:
shell> mysql db_name < script.sql > output.tab
MYSQL OPTIONS
mysql supports the following options:
--help, -?
Display a help message and exit.
--auto-rehash
Enable automatic rehashing. This option is on by default, which enables table and column name
completion. Use --skip-auto-rehash to disable rehashing. That causes mysql to start faster, but
you must issue the rehash command if you want to use table and column name completion.
--batch, -B
Print results using tab as the column separator, with each row on a new line. With this option,
mysql does not use the history file.
--character-sets-dir=path
The directory where character sets are installed. See Section 8.1, "The Character Set Used for
Data and Sorting".
--column-names
Write column names in results.
--compress, -C
Compress all information sent between the client and the server if both support compression.
--database=db_name, -D db_name
The database to use. This is useful primarily in an option file.
--debug[=debug_options], -# [debug_options]
Write a debugging log. The debug_options string often is 'd:t:o,file_name'. The default is
'd:t:o,/tmp/mysql.trace'.
--debug-info, -T
Print some debugging information when the program exits.
--default-character-set=charset_name
Use charset_name as the default character set. See Section 8.1, "The Character Set Used for Data
and Sorting".
--delimiter=str
Set the statement delimiter. The default is the semicolon character (`;').
--execute=statement, -e statement
Execute the statement and quit. The default output format is like that produced with --batch. See
Section 3.1, "Using Options on the Command Line", for some examples.
--force, -f
Continue even if an SQL error occurs.
--host=host_name, -h host_name
Connect to the MySQL server on the given host.
--html, -H
Produce HTML output.
--ignore-spaces, -i
Ignore spaces after function names. The effect of this is described in the discussion for the
IGNORE_SPACE SQL mode (see the section called "SQL MODES").
--line-numbers
Write line numbers for errors. Disable this with --skip-line-numbers.
--local-infile[={0|1}]
Enable or disable LOCAL capability for LOAD DATA INFILE. With no value, the option enables LOCAL.
The option may be given as --local-infile=0 or --local-infile=1 to explicitly disable or enable
LOCAL. Enabling LOCAL has no effect if the server does not also support it.

MySQL Network Monitoring and Advisory Service. For more information see
http://www.mysql.com/products/enterprise/advisors.html.
--named-commands, -G
Enable named mysql commands. Long-format commands are allowed, not just short-format commands. For
example, quit and \q both are recognized. Use --skip-named-commands to disable named commands. See
the section called "MYSQL COMMANDS".
--no-auto-rehash, -A
Deprecated form of -skip-auto-rehash. See the description for --auto-rehash.
--no-beep, -b
Do not beep when errors occur.
--no-named-commands, -g
Disable named commands. Use the \* form only, or use named commands only at the beginning of a
line ending with a semicolon (`;'). mysql starts with this option enabled by default. However,
even with this option, long-format commands still work from the first line. See the section called
"MYSQL COMMANDS".
--no-pager
Deprecated form of --skip-pager. See the --pager option.
--no-tee
Do not copy output to a file. the section called "MYSQL COMMANDS", discusses tee files further.
--one-database, -o
Ignore statements except those for the default database named on the command line. This is useful
for skipping updates to other databases in the binary log.
--pager[=command]
Use the given command for paging query output. If the command is omitted, the default pager is the
value of your PAGER environment variable. Valid pagers are less, more, cat [> filename], and so
forth. This option works only on Unix. It does not work in batch mode. To disable paging, use
--skip-pager. the section called "MYSQL COMMANDS", discusses output paging further.
--password[=password], -p[password]
The password to use when connecting to the server. If you use the short option form (-p), you
cannot have a space between the option and the password. If you omit the password value following
the --password or -p option on the command line, you are prompted for one.
Specifying a password on the command line should be considered insecure. See Section 6.6, "Keeping
Your Password Secure".
--port=port_num, -P port_num
The TCP/IP port number to use for the connection.
--prompt=format_str
Set the prompt to the specified format. The default is mysql>. The special sequences that the
prompt can contain are described in the section called "MYSQL COMMANDS".
--protocol={TCP|SOCKET|PIPE|MEMORY}
The connection protocol to use.
--quick, -q
Do not cache each query result, print each row as it is received. This may slow down the server if
the output is suspended. With this option, mysql does not use the history file.
--raw, -r
Write column values without escape conversion. Often used with the --batch option.
--reconnect
If the connection to the server is lost, automatically try to reconnect. A single reconnect
attempt is made each time the connection is lost. To suppress reconnection behavior, use
--skip-reconnect.
--safe-updates, --i-am-a-dummy, -U
Allow only those UPDATE and DELETE statements that specify which rows to modify by using key
values. If you have set this option in an option file, you can override it by using --safe-updates
on the command line. See the section called "MYSQL TIPS", for more information about this option.
--secure-auth
Do not send passwords to the server in old (pre-4.1.1) format. This prevents connections except
for servers that use the newer password format.

and Advisory Service. For more information see
http://www.mysql.com/products/enterprise/advisors.html
--show-warnings
Cause warnings to be shown after each statement if there are any. This option applies to
interactive and batch mode. This option was added in MySQL 5.0.6.
--sigint-ignore
Ignore SIGINT signals (typically the result of typing Control-C).
--silent, -s
Silent mode. Produce less output. This option can be given multiple times to produce less and less
output.
--skip-column-names, -N
Do not write column names in results.
--skip-line-numbers, -L
Do not write line numbers for errors. Useful when you want to compare result files that include
error messages.
--socket=path, -S path
For connections to localhost, the Unix socket file to use, or, on Windows, the name of the named
pipe to use.
--ssl*
Options that begin with --ssl specify whether to connect to the server via SSL and indicate where
to find SSL keys and certificates. See Section 6.7.3, "SSL Command Options".
--table, -t
Display output in table format. This is the default for interactive use, but can be used to
produce table output in batch mode.
--tee=file_name
Append a copy of output to the given file. This option does not work in batch mode. in the section
called "MYSQL COMMANDS", discusses tee files further.
--unbuffered, -n
Flush the buffer after each query.
--user=user_name, -u user_name
The MySQL username to use when connecting to the server.
--verbose, -v
Verbose mode. Produce more output about what the program does. This option can be given multiple
times to produce more and more output. (For example, -v -v -v produces table output format even in
batch mode.)
--version, -V
Display version information and exit.
--vertical, -E
Print query output rows vertically (one line per column value). Without this option, you can
specify vertical output for individual statements by terminating them with \G.
--wait, -w
If the connection cannot be established, wait and retry instead of aborting.
--xml, -X
Produce XML output.
Note: Prior to MySQL 5.0.26, there was no differentiation in the output when using this option
between columns containing the NULL value and columns containing the string literal 'NULL'; both
were represented as
<field name="column_name">NULL</field>
Beginning with MySQL 5.0.26, the output when --xml is used with mysql matches that of mysqldump
--xml. See the section of the Manual which discusses the --xml option for mysqldump for details.
Beginning with MySQL 5.0.40, the XML output also uses an XML namespace, as shown here:
shell> mysql --xml -uroot -e "SHOW VARIABLES LIKE 'version%'"
<?xml version="1.0"?>
<resultset statement="SHOW VARIABLES LIKE 'version%'" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<row>
<field name="Variable_name">version</field>
<field name="Value">5.0.40-debug</field>
</row>
<row>
<field name="Variable_name">version_comment</field>
<field name="Value">Source distribution</field>
</row>
<row>
<field name="Variable_name">version_compile_machine</field>
<field name="Value">i686</field>
</row>
<row>
<field name="Variable_name">version_compile_os</field>
<field name="Value">suse-linux-gnu</field>
</row>
</resultset>
(See [1]Bug#25946.)
You can also set the following variables by using --var_name=value syntax:
connect_timeout
The number of seconds before connection timeout. (Default value is 0.)
max_allowed_packet
The maximum packet length to send to or receive from the server. (Default value is 16MB.)
max_join_size
The automatic limit for rows in a join when using --safe-updates. (Default value is 1,000,000.)
net_buffer_length
The buffer size for TCP/IP and socket communication. (Default value is 16KB.)
select_limit
The automatic limit for SELECT statements when using --safe-updates. (Default value is 1,000.)
It is also possible to set variables by using --set-variable=var_name=value or -O var_name=value
syntax. This syntax is deprecated.
On Unix, the mysql client writes a record of executed statements to a history file. By default, the
history file is named .mysql_history and is created in your home directory. To specify a different
file, set the value of the MYSQL_HISTFILE environment variable.
If you do not want to maintain a history file, first remove .mysql_history if it exists, and then use
either of the following techniques:
Set the MYSQL_HISTFILE variable to /dev/null. To cause this setting to take effect each time you
log in, put the setting in one of your shell's startup files.
Create .mysql_history as a symbolic link to /dev/null:
shell> ln -s /dev/null $HOME/.mysql_history
You need do this only once.
MYSQL COMMANDS
mysql sends each SQL statement that you issue to the server to be executed. There is also a set of
commands that mysql itself interprets. For a list of these commands, type help or \h at the mysql>
prompt:
mysql> help
List of all MySQL commands:
Note that all text commands must be first on line and end with ';'
? (\?) Synonym for `help'.
charset (\C) Switch to another charset. Might be needed for processing
binlog with multi-byte charsets.
clear (\c) Clear command.
connect (\r) Reconnect to the server. Optional arguments are db and host.
delimiter (\d) Set statement delimiter. NOTE: Takes the rest of the line as
new delimiter.
edit (\e) Edit command with $EDITOR.
ego (\G) Send command to mysql server, display result vertically.
exit (\q) Exit mysql. Same as quit.
go (\g) Send command to mysql server.
help (\h) Display this help.
nopager (\n) Disable pager, print to stdout.
notee (\t) Don't write into outfile.
pager (\P) Set PAGER [to_pager]. Print the query results via PAGER.
print (\p) Print current command.
prompt (\R) Change your mysql prompt.
quit (\q) Quit mysql.
rehash (\#) Rebuild completion hash.
source (\.) Execute an SQL script file. Takes a file name as an argument.
status (\s) Get status information from the server.
system (\!) Execute a system shell command.
tee (\T) Set outfile [to_outfile]. Append everything into given
outfile.
use (\u) Use another database. Takes database name as argument.
warnings (\W) Show warnings after every statement.
nowarning (\w) Don't show warnings after every statement.
For server side help, type 'help contents'
Each command has both a long and short form. The long form is not case sensitive; the short form is.
The long form can be followed by an optional semicolon terminator, but the short form should not.
If you provide an argument to the help command, mysql uses it as a search string to access
server-side help from the contents of the MySQL Reference Manual. For more information, see the
section called "MYSQL SERVER-SIDE HELP".
The charset command changes the default character set and issues a SET NAMES statement. This enables
the character set to remain synchronized on the client and server if mysql is run with auto-reconnect
enabled (which is not recommended), because the changed character set is used for reconnects. This
command was added in MySQL 5.0.25.
In the delimiter command, you should avoid the use of the backslash (`\') character because that is
the escape character for MySQL.
The edit, nopager, pager, and system commands work only in Unix.
The status command provides some information about the connection and the server you are using. If
you are running in --safe-updates mode, status also prints the values for the mysql variables that
affect your queries.
To log queries and their output, use the tee command. All the data displayed on the screen is
appended into a given file. This can be very useful for debugging purposes also. You can enable this
feature on the command line with the --tee option, or interactively with the tee command. The tee
file can be disabled interactively with the notee command. Executing tee again re-enables logging.
Without a parameter, the previous file is used. Note that tee flushes query results to the file after
each statement, just before mysql prints its next prompt.
By using the --pager option, it is possible to browse or search query results in interactive mode
with Unix programs such as less, more, or any other similar program. If you specify no value for the
option, mysql checks the value of the PAGER environment variable and sets the pager to that. Output
paging can be enabled interactively with the pager command and disabled with nopager. The command
takes an optional argument; if given, the paging program is set to that. With no argument, the pager
is set to the pager that was set on the command line, or stdout if no pager was specified.
Output paging works only in Unix because it uses the popen() function, which does not exist on
Windows. For Windows, the tee option can be used instead to save query output, although this is not
as convenient as pager for browsing output in some situations.
Here are a few tips about the pager command:
You can use it to write to a file and the results go only to the file:
mysql> pager cat > /tmp/log.txt
You can also pass any options for the program that you want to use as your pager:
mysql> pager less -n -i -S
In the preceding example, note the -S option. You may find it very useful for browsing wide query
results. Sometimes a very wide result set is difficult to read on the screen. The -S option to
less can make the result set much more readable because you can scroll it horizontally using the
left-arrow and right-arrow keys. You can also use -S interactively within less to switch the
horizontal-browse mode on and off. For more information, read the less manual page:
shell> man less
You can specify very complex pager commands for handling query output:
mysql> pager cat | tee /dr1/tmp/res.txt \
| tee /dr2/tmp/res2.txt | less -n -i -S
In this example, the command would send query results to two files in two different directories on
two different filesystems mounted on /dr1 and /dr2, yet still display the results onscreen via less.
You can also combine the tee and pager functions. Have a tee file enabled and pager set to less, and
you are able to browse the results using the less program and still have everything appended into a
file the same time. The difference between the Unix tee used with the pager command and the mysql
built-in tee command is that the built-in tee works even if you do not have the Unix tee available.
The built-in tee also logs everything that is printed on the screen, whereas the Unix tee used with
pager does not log quite that much. Additionally, tee file logging can be turned on and off
interactively from within mysql. This is useful when you want to log some queries to a file, but not
others.
The default mysql> prompt can be reconfigured. The string for defining the prompt can contain the
following special sequences:
+-------------------------------+---------------------------------------+
|Option | Description |
+-------------------------------+---------------------------------------+
|\t | A tab character |
+-------------------------------+---------------------------------------+
|\ | A space (a space follows the |
| | backslash) |
+-------------------------------+---------------------------------------+
|\_ | A space |
+-------------------------------+---------------------------------------+
|\R | The current time, in 24-hour |
| | military time (0-23) |
+-------------------------------+---------------------------------------+
|\r | The current time, standard 12-hour |
| | time (1-12) |
+-------------------------------+---------------------------------------+
|\m | Minutes of the current time |
+-------------------------------+---------------------------------------+
|\y | The current year, two digits |
+-------------------------------+---------------------------------------+
|\Y | The current year, four digits |
+-------------------------------+---------------------------------------+
|\D | The full current date |
+-------------------------------+---------------------------------------+
|\s | Seconds of the current time |
+-------------------------------+---------------------------------------+
|\v | The server version |
+-------------------------------+---------------------------------------+
|\w | The current day of the week in |
| | three-letter format (Mon, Tue, ...) |
+-------------------------------+---------------------------------------+
|\P | am/pm |
+-------------------------------+---------------------------------------+
|\o | The current month in numeric format |
+-------------------------------+---------------------------------------+
|\O | The current month in three-letter |
| | format (Jan, Feb, ...) |
+-------------------------------+---------------------------------------+
|\c | A counter that increments for each |
| | statement you issue |
+-------------------------------+---------------------------------------+
|\l | The current delimiter. (New in |
| | 5.0.25) |
+-------------------------------+---------------------------------------+
|\S | Semicolon |
+-------------------------------+---------------------------------------+
|\' | Single quote |
+-------------------------------+---------------------------------------+
|\" | Double quote |
+-------------------------------+---------------------------------------+
|\d | The default database |
+-------------------------------+---------------------------------------+
|\h | The server host |
+-------------------------------+---------------------------------------+
|\p | The current TCP/IP port or socket |
| | file |
+-------------------------------+---------------------------------------+
|\u | Your username |
+-------------------------------+---------------------------------------+
|\U | Your full |
| | user_name@host_name |
| | account name |
+-------------------------------+---------------------------------------+
|\T}:T{ A literal `\' backslash | |
|character | |
+-------------------------------+---------------------------------------+
|\n | A newline character |
+-------------------------------+---------------------------------------+
`\' followed by any other letter just becomes that letter.
If you specify the prompt command with no argument, mysql resets the prompt to the default of mysql>.
You can set the prompt in several ways:
Use an environment variable. You can set the MYSQL_PS1 environment variable to a prompt string.
For example:
shell> export MYSQL_PS1="(\u@\h) [\d]> "
Use a command-line option. You can set the --prompt option on the command line to mysql. For
example:
shell> mysql --prompt="(\u@\h) [\d]> "
(user@host) [database]>
Use an option file. You can set the prompt option in the [mysql] group of any MySQL option file,
such as /etc/my.cnf or the .my.cnf file in your home directory. For example:
[mysql]
prompt=(\\u@\\h) [\\d]>\\_
In this example, note that the backslashes are doubled. If you set the prompt using the prompt option
in an option file, it is advisable to double the backslashes when using the special prompt options.
There is some overlap in the set of allowable prompt options and the set of special escape sequences
that are recognized in option files. (These sequences are listed in Section 3.2, "Using Option
Files".) The overlap may cause you problems if you use single backslashes. For example, \s is
interpreted as a space rather than as the current seconds value. The following example shows how to
define a prompt within an option file to include the current time in HH:MM:SS> format:
[mysql]
prompt="\\r:\\m:\\s> "
Set the prompt interactively. You can change your prompt interactively by using the prompt (or
\R) command. For example:
mysql> prompt (\u@\h) [\d]>\_
PROMPT set to '(\u@\h) [\d]>\_'
(user@host) [database]>
(user@host) [database]> prompt
Returning to default PROMPT of mysql>
mysql>
MYSQL SERVER-SIDE HELP
mysql> help search_string
If you provide an argument to the help command, mysql uses it as a search string to access
server-side help from the contents of the MySQL Reference Manual. The proper operation of this
command requires that the help tables in the mysql database be initialized with help topic
information (see the section called "SERVER-SIDE HELP").
If there is no match for the search string, the search fails:
mysql> help me
Nothing found
Please try to run 'help contents' for a list of all accessible topics
Use help contents to see a list of the help categories:
mysql> help contents
You asked for help about help category: "Contents"
For more information, type 'help <item>', where <item> is one of the
following categories:
Account Management
Administration
Data Definition
Data Manipulation
Data Types
Functions
Functions and Modifiers for Use with GROUP BY
Geographic Features
Language Structure
Storage Engines
Stored Routines
Table Maintenance
Transactions
Triggers
If the search string matches multiple items, mysql shows a list of matching topics:
mysql> help logs
Many help items for your request exist.
To make a more specific request, please type 'help <item>',
where <item> is one of the following topics:
SHOW
SHOW BINARY LOGS
SHOW ENGINE
SHOW LOGS
Use a topic as the search string to see the help entry for that topic:
mysql> help show binary logs
Name: 'SHOW BINARY LOGS'
Description:
Syntax:
SHOW BINARY LOGS
SHOW MASTER LOGS
Lists the binary log files on the server. This statement is used as
part of the procedure described in [purge-master-logs], that shows how
to determine which logs can be purged.
mysql> SHOW BINARY LOGS;
+---------------+-----------+
| Log_name | File_size |

| binlog.000016 | 733481 |
+---------------+-----------+
EXECUTING SQL STATEMENTS FROM A TEXT FILE
The mysql client typically is used interactively, like this:
shell> mysql db_name
However, it is also possible to put your SQL statements in a file and then tell mysql to read its
input from that file. To do so, create a text file text_file that contains the statements you wish to
execute. Then invoke mysql as shown here:
shell> mysql db_name < text_file
If you place a USE db_name statement as the first statement in the file, it is unnecessary to specify
the database name on the command line:
shell> mysql < text_file
If you are already running mysql, you can execute an SQL script file using the source command or \.
command:
mysql> source file_name
mysql> \. file_name
Sometimes you may want your script to display progress information to the user. For this you can
insert statements like this:
SELECT '<info_to_display>' AS ' ';
The statement shown outputs <info_to_display>.
For more information about batch mode, see Section 5, "Using mysql in Batch Mode".
MYSQL TIPS
This section describes some techniques that can help you use mysql more effectively.
Displaying Query Results Vertically
Some query results are much more readable when displayed vertically, instead of in the usual
horizontal table format. Queries can be displayed vertically by terminating the query with \G instead
of a semicolon. For example, longer text values that include newlines often are much easier to read
with vertical output:
mysql> SELECT * FROM mails WHERE LENGTH(txt) < 300 LIMIT 300,1\G
*************************** 1. row ***************************
msg_nro: 3068
date: 2000-03-01 23:29:50

Using the --safe-updates Option
For beginners, a useful startup option is --safe-updates (or --i-am-a-dummy, which has the same
effect). It is helpful for cases when you might have issued a DELETE FROM tbl_name statement but
forgotten the WHERE clause. Normally, such a statement deletes all rows from the table. With
--safe-updates, you can delete rows only by specifying the key values that identify them. This helps
prevent accidents.
When you use the --safe-updates option, mysql issues the following statement when it connects to the
MySQL server:
SET SQL_SAFE_UPDATES=1,SQL_SELECT_LIMIT=1000, SQL_MAX_JOIN_SIZE=1000000;
See Section 5.3, "SET Syntax".
The SET statement has the following effects:
You are not allowed to execute an UPDATE or DELETE statement unless you specify a key constraint
in the WHERE clause or provide a LIMIT clause (or both). For example:
UPDATE tbl_name SET not_key_column=val WHERE key_column=val;
UPDATE tbl_name SET not_key_column=val LIMIT 1;
The server limits all large SELECT results to 1,000 rows unless the statement includes a LIMIT
clause.
The server aborts multiple-table SELECT statements that probably need to examine more than
1,000,000 row combinations.
To specify limits different from 1,000 and 1,000,000, you can override the defaults by using the
--select_limit and --max_join_size options:
shell> mysql --safe-updates --select_limit=500 --max_join_size=10000
Disabling mysql Auto-Reconnect
If the mysql client loses its connection to the server while sending a statement, it immediately and
automatically tries to reconnect once to the server and send the statement again. However, even if
mysql succeeds in reconnecting, your first connection has ended and all your previous session objects
and settings are lost: temporary tables, the autocommit mode, and user-defined and session variables.
Also, any current transaction rolls back. This behavior may be dangerous for you, as in the following
example where the server was shut down and restarted between the first and second statements without
you knowing it:
mysql> SET @a=1;
Query OK, 0 rows affected (0.05 sec)
mysql> INSERT INTO t VALUES(@a);
ERROR 2006: MySQL server has gone away
No connection. Trying to reconnect...
Connection id: 1
Current database: test
Query OK, 1 row affected (1.30 sec)
mysql> SELECT * FROM t;
+------+
| a |
+------+
| NULL |
+------+
1 row in set (0.05 sec)
The @a user variable has been lost with the connection, and after the reconnection it is undefined.
If it is important to have mysql terminate with an error if the connection has been lost, you can
start the mysql client with the --skip-reconnect option.
For more information about auto-reconnect and its effect on state information when a reconnection
occurs, see Section 2.13, "Controlling Automatic Reconnect Behavior".
