--help, -?

Display a help message and exit.

--auto-rehash

Enable automatic rehashing. This option is on by default, which enables database, table, and column name completion. Use --disable-auto-rehash to disable rehashing. That causes mysql to start faster, but you must issue the rehash command or its \# shortcut if you want to use name completion.

To complete a name, enter the first part and press Tab. If the name is unambiguous, mysql completes it. Otherwise, you can press Tab again to see the possible names that begin with what you have typed so far. Completion does not occur if there is no default database.

--auto-vertical-output

Cause result sets to be displayed vertically if they are too wide for the current window, and using normal tabular format otherwise. (This applies to statements terminated by ; or \G.)

--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.

Batch mode results in nontabular output format and escaping of special characters. Escaping may be disabled by using raw mode; see the description for the --raw option.

--binary-as-hex

When this option is given, mysql displays binary data using hexadecimal notation (0xvalue). This occurs whether the overall output display format is tabular, vertical, HTML, or XML.

--binary-as-hex when enabled affects display of all binary strings, including those returned by functions such as CHAR() and UNHEX(). The following example demonstrates this using the ASCII code for A (65 decimal, 41 hexadecimal):

To write a binary string expression so that it displays as a character string regardless of whether --binary-as-hex is enabled, use these techniques:

When mysql operates in interactive mode, this option is enabled by default. In addition, output from the status (or \s) command includes this line when the option is enabled implicitly or explicitly:

Binary data as: Hexadecimal

To disable hexadecimal notation, use --skip-binary-as-hex

--binary-mode

This option helps when processing mysqlbinlog output that may contain BLOB values. By default, mysql translates \r\n in statement strings to \n and interprets \0 as the statement terminator. --binary-mode disables both features. It also disables all mysql commands except charset and delimiter in noninteractive mode (for input piped to mysql or loaded using the source command).

--bind-address=ip_address

On a computer having multiple network interfaces, use this option to select which interface to use for connecting to the MySQL server.

--character-sets-dir=dir_name

The directory where character sets are installed. See Section 12.15, “Character Set Configuration”.

--column-names

Write column names in results.

--column-type-info

Display result set metadata. This information corresponds to the contents of C API MYSQL_FIELD data structures. See C API Basic Data Structures.

--comments, -c

Whether to preserve or strip comments in statements sent to the server. The default is to preserve them; to strip them, start mysql with --skip-comments.

--compress, -C

Compress all information sent between the client and the server if possible. See Section 6.2.8, “Connection Compression Control”.

This option is deprecated. Expect it to be removed in a future version of MySQL. See Configuring Legacy Connection Compression.

--compression-algorithms=value

The permitted compression algorithms for connections to the server. The available algorithms are the same as for the protocol_compression_algorithms system variable. The default value is uncompressed.

For more information, see Section 6.2.8, “Connection Compression Control”.

--connect-expired-password

Indicate to the server that the client can handle sandbox mode if the account used to connect has an expired password. This can be useful for noninteractive invocations of mysql because normally the server disconnects noninteractive clients that attempt to connect using an account with an expired password. (See Section 8.2.16, “Server Handling of Expired Passwords”.)

--connect-timeout=value

The number of seconds before connection timeout. (Default value is 0.)

--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. A typical debug_options string is d:t:o,file_name. The default is d:t:o,/tmp/mysql.trace.

This option is available only if MySQL was built using WITH_DEBUG. MySQL release binaries provided by Oracle are not built using this option.

--debug-check

Print some debugging information when the program exits.

This option is available only if MySQL was built using WITH_DEBUG. MySQL release binaries provided by Oracle are not built using this option.

--debug-info, -T

Print debugging information and memory and CPU usage statistics when the program exits.

This option is available only if MySQL was built using WITH_DEBUG. MySQL release binaries provided by Oracle are not built using this option.

--default-auth=plugin

A hint about which client-side authentication plugin to use. See Section 8.2.17, “Pluggable Authentication”.

--default-character-set=charset_name

Use charset_name as the default character set for the client and connection.

This option can be useful if the operating system uses one character set and the mysql client by default uses another. In this case, output may be formatted incorrectly. You can usually fix such issues by using this option to force the client to use the system character set instead.

For more information, see Section 12.4, “Connection Character Sets and Collations”, and Section 12.15, “Character Set Configuration”.

--defaults-extra-file=file_name

Read this option file after the global option file but (on Unix) before the user option file. If the file does not exist or is otherwise inaccessible, an error occurs. If file_name is not an absolute path name, it is interpreted relative to the current directory.

For additional information about this and other option-file options, see Section 6.2.2.3, “Command-Line Options that Affect Option-File Handling”.

--defaults-file=file_name

Use only the given option file. If the file does not exist or is otherwise inaccessible, an error occurs. If file_name is not an absolute path name, it is interpreted relative to the current directory.

Exception: Even with --defaults-file, client programs read .mylogin.cnf.

For additional information about this and other option-file options, see Section 6.2.2.3, “Command-Line Options that Affect Option-File Handling”.

--defaults-group-suffix=str

Read not only the usual option groups, but also groups with the usual names and a suffix of str. For example, mysql normally reads the [client] and [mysql] groups. If this option is given as --defaults-group-suffix=_other, mysql also reads the [client_other] and [mysql_other] groups.

For additional information about this and other option-file options, see Section 6.2.2.3, “Command-Line Options that Affect Option-File Handling”.

--delimiter=str

Set the statement delimiter. The default is the semicolon character (;).

--disable-named-commands

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 Section 6.5.1.2, “mysql Client Commands”.

--dns-srv-name=name

Specifies the name of a DNS SRV record that determines the candidate hosts to use for establishing a connection to a MySQL server. For information about DNS SRV support in MySQL, see Section 6.2.6, “Connecting to the Server Using DNS SRV Records”.

Suppose that DNS is configured with this SRV information for the example.com domain:

Name                     TTL   Class   Priority Weight Port Target
_mysql._tcp.example.com. 86400 IN SRV  0        5      3306 host1.example.com
_mysql._tcp.example.com. 86400 IN SRV  0        10     3306 host2.example.com
_mysql._tcp.example.com. 86400 IN SRV  10       5      3306 host3.example.com
_mysql._tcp.example.com. 86400 IN SRV  20       5      3306 host4.example.com

To use that DNS SRV record, invoke mysql like this:

mysql --dns-srv-name=_mysql._tcp.example.com

mysql then attempts a connection to each server in the group until a successful connection is established. A failure to connect occurs only if a connection cannot be established to any of the servers. The priority and weight values in the DNS SRV record determine the order in which servers should be tried.

When invoked with --dns-srv-name, mysql attempts to establish TCP connections only.

The --dns-srv-name option takes precedence over the --host option if both are given. --dns-srv-name causes connection establishment to use the mysql_real_connect_dns_srv() C API function rather than mysql_real_connect(). However, if the connect command is subsequently used at runtime and specifies a host name argument, that host name takes precedence over any --dns-srv-name option given at mysql startup to specify a DNS SRV record.

--enable-cleartext-plugin

Enable the mysql_clear_password cleartext authentication plugin. (See Section 8.4.1.4, “Client-Side Cleartext Pluggable Authentication”.)

--execute=statement, -e statement

Execute the statement and quit. The default output format is like that produced with --batch. See Section 6.2.2.1, “Using Options on the Command Line”, for some examples. With this option, mysql does not use the history file.

--force, -f

Continue even if an SQL error occurs.

--get-server-public-key

Request from the server the public key required for RSA key pair-based password exchange. This option applies to clients that authenticate with the caching_sha2_password authentication plugin. For that plugin, the server does not send the public key unless requested. This option is ignored for accounts that do not authenticate with that plugin. It is also ignored if RSA-based password exchange is not used, as is the case when the client connects to the server using a secure connection.

If --server-public-key-path=file_name is given and specifies a valid public key file, it takes precedence over --get-server-public-key.

For information about the caching_sha2_password plugin, see Section 8.4.1.2, “Caching SHA-2 Pluggable Authentication”.

--histignore

A list of one or more colon-separated patterns specifying statements to ignore for logging purposes. These patterns are added to the default pattern list ("*IDENTIFIED*:*PASSWORD*"). The value specified for this option affects logging of statements written to the history file, and to syslog if the --syslog option is given. For more information, see Section 6.5.1.3, “mysql Client Logging”.

--host=host_name, -h host_name

Connect to the MySQL server on the given host.

The --dns-srv-name option takes precedence over the --host option if both are given. --dns-srv-name causes connection establishment to use the mysql_real_connect_dns_srv() C API function rather than mysql_real_connect(). However, if the connect command is subsequently used at runtime and specifies a host name argument, that host name takes precedence over any --dns-srv-name option given at mysql startup to specify a DNS SRV record.

--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 Section 7.1.11, “Server SQL Modes”).

--init-command=str

Single SQL statement to execute after connecting to the server. If auto-reconnect is enabled, the statement is executed again after reconnection occurs. The definition resets existing statements defined by it or init-command-add.

--init-command-add=str

Add an additional SQL statement to execute after connecting or reconnecting to the MySQL server. It's usable without --init-command but has no effect if used before it because init-command resets the list of commands to call.

--line-numbers

Write line numbers for errors. Disable this with --skip-line-numbers.

--load-data-local-dir=dir_name

This option affects the client-side LOCAL capability for LOAD DATA operations. It specifies the directory in which files named in LOAD DATA LOCAL statements must be located. The effect of --load-data-local-dir depends on whether LOCAL data loading is enabled or disabled:

When --load-data-local-dir applies, the option value designates the directory in which local data files must be located. Comparison of the directory path name and the path name of files to be loaded is case-sensitive regardless of the case sensitivity of the underlying file system. If the option value is the empty string, it names no directory, with the result that no files are permitted for local data loading.

For example, to explicitly disable local data loading except for files located in the /my/local/data directory, invoke mysql like this:

mysql --local-infile=0 --load-data-local-dir=/my/local/data

When both --local-infile and --load-data-local-dir are given, the order in which they are given does not matter.

Successful use of LOCAL load operations within mysql also requires that the server permits local loading; see Section 8.1.6, “Security Considerations for LOAD DATA LOCAL”

--local-infile[={0|1}]

By default, LOCAL capability for LOAD DATA is determined by the default compiled into the MySQL client library. To enable or disable LOCAL data loading explicitly, use the --local-infile option. When given with no value, the option enables LOCAL data loading. When given as --local-infile=0 or --local-infile=1, the option disables or enables LOCAL data loading.

If LOCAL capability is disabled, the --load-data-local-dir option can be used to permit restricted local loading of files located in a designated directory.

Successful use of LOCAL load operations within mysql also requires that the server permits local loading; see Section 8.1.6, “Security Considerations for LOAD DATA LOCAL”

--login-path=name

Read options from the named login path in the .mylogin.cnf login path file. A “login path” is an option group containing options that specify which MySQL server to connect to and which account to authenticate as. To create or modify a login path file, use the mysql_config_editor utility. See Section 6.6.7, “mysql_config_editor — MySQL Configuration Utility”.

For additional information about this and other option-file options, see Section 6.2.2.3, “Command-Line Options that Affect Option-File Handling”.

--no-login-paths

Skips reading options from the login path file.

See --login-path for related information.

For additional information about this and other option-file options, see Section 6.2.2.3, “Command-Line Options that Affect Option-File Handling”.

--max-allowed-packet=value

The maximum size of the buffer for client/server communication. The default is 16MB, the maximum is 1GB.

--max-join-size=value

The automatic limit for rows in a join when using --safe-updates. (Default value is 1,000,000.)

--named-commands, -G

Enable named mysql commands. Long-format commands are permitted, not just short-format commands. For example, quit and \q both are recognized. Use --skip-named-commands to disable named commands. See Section 6.5.1.2, “mysql Client Commands”.

--net-buffer-length=value

The buffer size for TCP/IP and socket communication. (Default value is 16KB.)

--network-namespace=name

The network namespace to use for TCP/IP connections. If omitted, the connection uses the default (global) namespace. For information about network namespaces, see Section 7.1.14, “Network Namespace Support”.

This option is available only on platforms that implement network namespace support.

--no-auto-rehash, -A

This has the same effect as --skip-auto-rehash. See the description for --auto-rehash.

--no-beep, -b

Do not beep when errors occur.

--no-defaults

Do not read any option files. If program startup fails due to reading unknown options from an option file, --no-defaults can be used to prevent them from being read.

The exception is that the .mylogin.cnf file is read in all cases, if it exists. This permits passwords to be specified in a safer way than on the command line even when --no-defaults is used. To create .mylogin.cnf, use the mysql_config_editor utility. See Section 6.6.7, “mysql_config_editor — MySQL Configuration Utility”.

For additional information about this and other option-file options, see Section 6.2.2.3, “Command-Line Options that Affect Option-File Handling”.

--oci-config-file=PATH

Alternate path to the Oracle Cloud Infrastructure CLI configuration file. Specify the location of the configuration file. If your existing default profile is the correct one, you do not need to specify this option. However, if you have an existing configuration file, with multiple profiles or a different default from the tenancy of the user you want to connect with, specify this option.

--one-database, -o

Ignore statements except those that occur while the default database is the one named on the command line. This option is rudimentary and should be used with care. Statement filtering is based only on USE statements.

Initially, mysql executes statements in the input because specifying a database db_name on the command line is equivalent to inserting USE db_name at the beginning of the input. Then, for each USE statement encountered, mysql accepts or rejects following statements depending on whether the database named is the one on the command line. The content of the statements is immaterial.

Suppose that mysql is invoked to process this set of statements:

DELETE FROM db2.t2;
USE db2;
DROP TABLE db1.t1;
CREATE TABLE db1.t1 (i INT);
USE db1;
INSERT INTO t1 (i) VALUES(1);
CREATE TABLE db2.t1 (j INT);

If the command line is mysql --force --one-database db1, mysql handles the input as follows:

--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 and only in interactive mode. To disable paging, use --skip-pager. Section 6.5.1.2, “mysql Client Commands”, discusses output paging further.

--password[=password], -p[password]

The password of the MySQL account used for connecting to the server. The password value is optional. If not given, mysql prompts for one. If given, there must be no space between --password= or -p and the password following it. If no password option is specified, the default is to send no password.

Specifying a password on the command line should be considered insecure. To avoid giving the password on the command line, use an option file. See Section 8.1.2.1, “End-User Guidelines for Password Security”.

To explicitly specify that there is no password and that mysql should not prompt for one, use the --skip-password option.

--password1[=pass_val]

The password for multifactor authentication factor 1 of the MySQL account used for connecting to the server. The password value is optional. If not given, mysql prompts for one. If given, there must be no space between --password1= and the password following it. If no password option is specified, the default is to send no password.

Specifying a password on the command line should be considered insecure. To avoid giving the password on the command line, use an option file. See Section 8.1.2.1, “End-User Guidelines for Password Security”.

To explicitly specify that there is no password and that mysql should not prompt for one, use the --skip-password1 option.

--password1 and --password are synonymous, as are --skip-password1 and --skip-password.

--password2[=pass_val]

The password for multifactor authentication factor 2 of the MySQL account used for connecting to the server. The semantics of this option are similar to the semantics for --password1; see the description of that option for details.

--password3[=pass_val]

The password for multifactor authentication factor 3 of the MySQL account used for connecting to the server. The semantics of this option are similar to the semantics for --password1; see the description of that option for details.

--pipe, -W

On Windows, connect to the server using a named pipe. This option applies only if the server was started with the named_pipe system variable enabled to support named-pipe connections. In addition, the user making the connection must be a member of the Windows group specified by the named_pipe_full_access_group system variable.

--plugin-authentication-kerberos-client-mode=value

On Windows, the authentication_kerberos_client authentication plugin supports this plugin option. It provides two possible values that the client user can set at runtime: SSPI and GSSAPI.

The default value for the client-side plugin option uses Security Support Provider Interface (SSPI), which is capable of acquiring credentials from the Windows in-memory cache. Alternatively, the client user can select a mode that supports Generic Security Service Application Program Interface (GSSAPI) through the MIT Kerberos library on Windows. GSSAPI is capable of acquiring cached credentials previously generated by using the kinit command.

For more information, see Commands for Windows Clients in GSSAPI Mode.

--plugin-authentication-webauthn-client-preserve-privacy={OFF|ON}

Determines how assertions are sent to server in case there is more than one discoverable credential stored for a given RP ID (a unique name given to the relying-party server, which is the MySQL server). If the FIDO2 device contains multiple resident keys for a given RP ID, this option allows the user to choose a key to be used for assertion. It provides two possible values that the client user can set. The default value is OFF. If set to OFF, the challenge is signed by all credentials available for a given RP ID and all signatures are sent to server. If set to ON, the user is prompted to choose the credential to be used for signature.

For more information, see Section 8.4.1.11, “WebAuthn Pluggable Authentication”.

--plugin-dir=dir_name

The directory in which to look for plugins. Specify this option if the --default-auth option is used to specify an authentication plugin but mysql does not find it. See Section 8.2.17, “Pluggable Authentication”.

--port=port_num, -P port_num

For TCP/IP connections, the port number to use.

--print-defaults

Print the program name and all options that it gets from option files.

For additional information about this and other option-file options, see Section 6.2.2.3, “Command-Line Options that Affect Option-File Handling”.

--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 Section 6.5.1.2, “mysql Client Commands”.

--protocol={TCP|SOCKET|PIPE|MEMORY}

The transport protocol to use for connecting to the server. It is useful when the other connection parameters normally result in use of a protocol other than the one you want. For details on the permissible values, see Section 6.2.7, “Connection Transport Protocols”.

--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.

By default, mysql fetches all result rows before producing any output; while storing these, it calculates a running maximum column length from the actual value of each column in succession. When printing the output, it uses this maximum to format it. When --quick is specified, mysql does not have the rows for which to calculate the length before starting, and so uses the maximum length. In the following example, table t1 has a single column of type BIGINT and containing 4 rows. The default output is 9 characters wide; this width is equal the maximum number of characters in any of the column values in the rows returned (5), plus 2 characters each for the spaces used as padding and the | characters used as column delimiters). The output when using the --quick option is 25 characters wide; this is equal to the number of characters needed to represent -9223372036854775808, which is the longest possible value that can be stored in a (signed) BIGINT column, or 19 characters, plus the 4 characters used for padding and column delimiters. The difference can be seen here:

$> mysql -t test -e "SELECT * FROM t1"
+-------+
| c1    |
+-------+
|   100 |
|  1000 |
| 10000 |
|    10 |
+-------+

$> mysql --quick -t test -e "SELECT * FROM t1"
+----------------------+
| c1                   |
+----------------------+
|                  100 |
|                 1000 |
|                10000 |
|                   10 |
+----------------------+

--raw, -r

For tabular output, the “boxing” around columns enables one column value to be distinguished from another. For nontabular output (such as is produced in batch mode or when the --batch or --silent option is given), special characters are escaped in the output so they can be identified easily. Newline, tab, NUL, and backslash are written as \n, \t, \0, and \\. The --raw option disables this character escaping.

The following example demonstrates tabular versus nontabular output and the use of raw mode to disable escaping:

% mysql
mysql> SELECT CHAR(92);
+----------+
| CHAR(92) |
+----------+
| \        |
+----------+

% mysql -s
mysql> SELECT CHAR(92);
CHAR(92)
\\

% mysql -s -r
mysql> SELECT CHAR(92);
CHAR(92)
\

--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.

--register-factor=value

The factor or factors for which FIDO/FIDO2 device registration must be performed before WebAuthn device-based authentication can be used. This option value must be a single value, or two values separated by commas. Each value must be 2 or 3, so the permitted option values are '2', '3', '2,3' and '3,2'.

For example, an account that requires registration for a third authentication factor invokes the mysql client as follows:

mysql --user=user_name --register-factor=3

An account that requires registration for second and third authentication factors invokes the mysql client as follows:

mysql --user=user_name --register-factor=2,3

If registration is successful, a connection is established. If there is an authentication factor with a pending registration, a connection is placed into pending registration mode when attempting to connect to the server. In this case, disconnect and reconnect with the correct --register-factor value to complete the registration.

Registration is a two-step process comprising initiate registration and finish registration steps. The initiate registration step executes this statement:

ALTER USER user factor INITIATE REGISTRATION

The statement returns a result set containing a 32 byte challenge, the user name, and the relying party ID (see authentication_webauthn_rp_id).

The finish registration step executes this statement:

ALTER USER user factor FINISH REGISTRATION SET CHALLENGE_RESPONSE AS 'auth_string'

The statement completes the registration and sends the following information to the server as part of the auth_string: authenticator data, an optional attestation certificate in X.509 format, and a signature.

The initiate and registration steps must be performed in a single connection, as the challenge received by the client during the initiate step is saved to the client connection handler. Registration would fail if the registration step was performed by a different connection. The --register-factor option executes both the initiate and registration steps, which avoids the failure scenario described above and prevents having to execute the ALTER USER initiate and registration statements manually.

The --register-factor option is only available for the mysql and MySQL Shell clients. Other MySQL client programs do not support it.

For related information, see Using WebAuthn Authentication.

--safe-updates, --i-am-a-dummy, -U

If this option is enabled, UPDATE and DELETE statements that do not use a key in the WHERE clause or a LIMIT clause produce an error. In addition, restrictions are placed on SELECT statements that produce (or are estimated to produce) very large result sets. If you have set this option in an option file, you can use --skip-safe-updates on the command line to override it. For more information about this option, see Using Safe-Updates Mode (--safe-updates).

--select-limit=value

The automatic limit for SELECT statements when using --safe-updates. (Default value is 1,000.)

--server-public-key-path=file_name

The path name to a file in PEM format containing a client-side copy of the public key required by the server for RSA key pair-based password exchange. This option applies to clients that authenticate with the sha256_password or caching_sha2_password authentication plugin. This option is ignored for accounts that do not authenticate with one of those plugins. It is also ignored if RSA-based password exchange is not used, as is the case when the client connects to the server using a secure connection.

If --server-public-key-path=file_name is given and specifies a valid public key file, it takes precedence over --get-server-public-key.

For sha256_password, this option applies only if MySQL was built using OpenSSL.

For information about the sha256_password and caching_sha2_password plugins, see Section 8.4.1.3, “SHA-256 Pluggable Authentication”, and Section 8.4.1.2, “Caching SHA-2 Pluggable Authentication”.

--shared-memory-base-name=name

On Windows, the shared-memory name to use for connections made using shared memory to a local server. The default value is MYSQL. The shared-memory name is case-sensitive.

This option applies only if the server was started with the shared_memory system variable enabled to support shared-memory connections.

--show-warnings

Cause warnings to be shown after each statement if there are any. This option applies to interactive and batch mode.

--sigint-ignore

Ignore SIGINT signals (typically the result of typing Control+C).

Without this option, typing Control+C interrupts the current statement if there is one, or cancels any partial input line otherwise.

--silent, -s

Silent mode. Produce less output. This option can be given multiple times to produce less and less output.

This option results in nontabular output format and escaping of special characters. Escaping may be disabled by using raw mode; see the description for the --raw option.

--skip-column-names, -N

Do not write column names in results. Use of this option causes the output to be right-aligned, as shown here:

$> echo "SELECT * FROM t1" | mysql -t test
+-------+
| c1    |
+-------+
| a,c,d |
| c     |
+-------+
$> echo "SELECT * FROM t1" | ./mysql -uroot -Nt test
+-------+
| a,c,d |
|     c |
+-------+

--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.

On Windows, this option applies only if the server was started with the named_pipe system variable enabled to support named-pipe connections. In addition, the user making the connection must be a member of the Windows group specified by the named_pipe_full_access_group system variable.

--ssl*

Options that begin with --ssl specify whether to connect to the server using encryption and indicate where to find SSL keys and certificates. See Command Options for Encrypted Connections.

--ssl-fips-mode={OFF|ON|STRICT}

Controls whether to enable FIPS mode on the client side. The --ssl-fips-mode option differs from other --ssl-xxx options in that it is not used to establish encrypted connections, but rather to affect which cryptographic operations to permit. See Section 8.8, “FIPS Support”.

These --ssl-fips-mode values are permitted:

This option is deprecated. Expect it to be removed in a future version of MySQL.

--syslog, -j

This option causes mysql to send interactive statements to the system logging facility. On Unix, this is syslog; on Windows, it is the Windows Event Log. The destination where logged messages appear is system dependent. On Linux, the destination is often the /var/log/messages file.

Here is a sample of output generated on Linux by using --syslog. This output is formatted for readability; each logged message actually takes a single line.

Mar  7 12:39:25 myhost MysqlClient[20824]:
  SYSTEM_USER:'oscar', MYSQL_USER:'my_oscar', CONNECTION_ID:23,
  DB_SERVER:'127.0.0.1', DB:'--', QUERY:'USE test;'
Mar  7 12:39:28 myhost MysqlClient[20824]:
  SYSTEM_USER:'oscar', MYSQL_USER:'my_oscar', CONNECTION_ID:23,
  DB_SERVER:'127.0.0.1', DB:'test', QUERY:'SHOW TABLES;'

For more information, see Section 6.5.1.3, “mysql Client Logging”.

--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 works only in interactive mode. Section 6.5.1.2, “mysql Client Commands”, discusses tee files further.

--tls-ciphersuites=ciphersuite_list

The permissible ciphersuites for encrypted connections that use TLSv1.3. The value is a list of one or more colon-separated ciphersuite names. The ciphersuites that can be named for this option depend on the SSL library used to compile MySQL. For details, see Section 8.3.2, “Encrypted Connection TLS Protocols and Ciphers”.

--tls-sni-servername=server_name

When specified, the name is passed to the libmysqlclient C API library using the MYSQL_OPT_TLS_SNI_SERVERNAME option of mysql_options(). The server name is not case-sensitive. To show which server name the client specified for the current session, if any, check the Tls_sni_server_name status variable.

Server Name Indication (SNI) is an extension to the TLS protocol (OpenSSL must be compiled using TLS extensions for this option to function). The MySQL implementation of SNI represents the client-side only.

--tls-version=protocol_list

The permissible TLS protocols for encrypted connections. The value is a list of one or more comma-separated protocol names. The protocols that can be named for this option depend on the SSL library used to compile MySQL. For details, see Section 8.3.2, “Encrypted Connection TLS Protocols and Ciphers”.

--unbuffered, -n

Flush the buffer after each query.

--user=user_name, -u user_name

The user name of the MySQL account to use for 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.

<field name="column_name">NULL</field>

The output when --xml is used with mysql matches that of mysqldump --xml. See Section 6.5.4, “mysqldump — A Database Backup Program”, for details.

The XML output also uses an XML namespace, as shown here:

$> 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>

--zstd-compression-level=level

The compression level to use for connections to the server that use the zstd compression algorithm. The permitted levels are from 1 to 22, with larger values indicating increasing levels of compression. The default zstd compression level is 3. The compression level setting has no effect on connections that do not use zstd compression.

For more information, see Section 6.2.8, “Connection Compression Control”.

telemetry_client

Enables the telemetry client plugin (Linux only).
