MYSQLIMPORT(1) MySQL Database System MYSQLIMPORT(1) # [NAME](#NAME) mysqlimport - a data import program # [SYNOPSIS](#SYNOPSIS) **mysqlimport \[options] db\_name textfile1 ...** # [DESCRIPTION](#DESCRIPTION) The **mysqlimport** client provides a command-line interface to the LOAD DATA SQL statement. Most options to **mysqlimport** correspond directly to clauses of LOAD DATA syntax. See Section 13.2.9, “LOAD DATA Statement”. Invoke **mysqlimport** like this: ``` mysqlimport [options] db_name textfile1 [textfile2 ...] ``` For each text file named on the command line, **mysqlimport** strips any extension from the file name and uses the result to determine the name of the table into which to import the file's contents. For example, files named patient.txt, patient.text, and patient all would be imported into a table named patient. **mysqlimport** supports the following options, which can be specified on the command line or in the \[mysqlimport] and \[client] groups of an option file. For information about option files used by MySQL programs, see Section 4.2.2.2, “Using Option Files”. •**--help**, **-?** Display a help message and exit. •**--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 10.15, “Character Set Configuration”. •**--columns=column\_list**, **-c column\_list** This option takes a list of comma-separated column names as its value. The order of the column names indicates how to match data file columns with table columns. •**--compress**, **-C** Compress all information sent between the client and the server if possible. See Section 4.2.8, “Connection Compression Control”. As of MySQL 8.0.18, this option is deprecated. Expect it to be removed in a future version of MySQL. See the section called “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 4.2.8, “Connection Compression Control”. This option was added in MySQL 8.0.18. •**--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. 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** 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-character-set=charset\_name** Use *charset\_name* as the default character set. See Section 10.15, “Character Set Configuration”. •**--default-auth=plugin** A hint about which client-side authentication plugin to use. See Section 6.2.17, “Pluggable Authentication”. •**--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 4.2.2.3, “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 4.2.2.3, “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, **mysqlimport** normally reads the \[client] and \[mysqlimport] groups. If this option is given as **--defaults-group-suffix=\_other**, **mysqlimport** also reads the \[client\_other] and \[mysqlimport\_other] groups. For additional information about this and other option-file options, see Section 4.2.2.3, “Command-Line Options that Affect Option-File Handling”. •**--delete**, **-D** Empty the table before importing the text file. •**--enable-cleartext-plugin** Enable the mysql\_clear\_password cleartext authentication plugin. (See Section 6.4.1.4, “Client-Side Cleartext Pluggable Authentication”.) •**--fields-terminated-by=...**, **--fields-enclosed-by=...**, **--fields-optionally-enclosed-by=...**, **--fields-escaped-by=...** These options have the same meaning as the corresponding clauses for LOAD DATA. See Section 13.2.9, “LOAD DATA Statement”. •**--force**, **-f** Ignore errors. For example, if a table for a text file does not exist, continue processing any remaining files. Without **--force**, **mysqlimport** exits if a table does not exist. •**--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 6.4.1.2, “Caching SHA-2 Pluggable Authentication”. •**--host=host\_name**, **-h host\_name** Import data to the MySQL server on the given host. The default host is localhost. •**--ignore**, **-i** See the description for the **--replace** option. •**--ignore-lines=N** Ignore the first *N* lines of the data file. •**--lines-terminated-by=...** This option has the same meaning as the corresponding clause for LOAD DATA. For example, to import Windows files that have lines terminated with carriage return/linefeed pairs, use **--lines-terminated-by="\\r\\n"**. (You might have to double the backslashes, depending on the escaping conventions of your command interpreter.) See Section 13.2.9, “LOAD DATA Statement”. •**--local**, **-L** By default, files are read by the server on the server host. With this option, **mysqlimport** reads input files locally on the client host. Successful use of LOCAL load operations within **mysqlimport** also requires that the server permits local loading; see Section 6.1.6, “Security Considerations for LOAD DATA LOCAL” •**--lock-tables**, **-l** Lock *all* tables for writing before processing any text files. This ensures that all tables are synchronized on the server. •**--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 [mysql\_config\_editor(1)](/man/enterprise-packages/percona-xtrabackup-8.0/mysql_config_editor.1). For additional information about this and other option-file options, see Section 4.2.2.3, “Command-Line Options that Affect Option-File Handling”. •**--low-priority** Use LOW\_PRIORITY when loading the table. This affects only storage engines that use only table-level locking (such as MyISAM, MEMORY, and MERGE). •**--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 [mysql\_config\_editor(1)](/man/enterprise-packages/percona-xtrabackup-8.0/mysql_config_editor.1). For additional information about this and other option-file options, see Section 4.2.2.3, “Command-Line Options that Affect Option-File Handling”. •**--password\[=password]**, **-p\[password]** The password of the MySQL account used for connecting to the server. The password value is optional. If not given, **mysqlimport** 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 6.1.2.1, “End-User Guidelines for Password Security”. To explicitly specify that there is no password and that **mysqlimport** 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, **mysqlimport** 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 6.1.2.1, “End-User Guidelines for Password Security”. To explicitly specify that there is no password and that **mysqlimport** 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-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 **mysqlimport** does not find it. See Section 6.2.17, “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 4.2.2.3, “Command-Line Options that Affect Option-File Handling”. •**--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 4.2.7, “Connection Transport Protocols”. •**--replace**, **-r** The **--replace** and **--ignore** options control handling of input rows that duplicate existing rows on unique key values. If you specify **--replace**, new rows replace existing rows that have the same unique key value. If you specify **--ignore**, input rows that duplicate an existing row on a unique key value are skipped. If you do not specify either option, an error occurs when a duplicate key value is found, and the rest of the text file is ignored. •**--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 6.4.1.3, “SHA-256 Pluggable Authentication”, and Section 6.4.1.2, “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. •**--silent**, **-s** Silent mode. Produce output only when errors occur. •**--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 the section called “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 6.8, “FIPS Support”. These **--ssl-fips-mode** values are permitted: •OFF: Disable FIPS mode. •ON: Enable FIPS mode. •STRICT: Enable “strict” FIPS mode. **Note** If the OpenSSL FIPS Object Module is not available, the only permitted value for **--ssl-fips-mode** is OFF. In this case, setting **--ssl-fips-mode** to ON or STRICT causes the client to produce a warning at startup and to operate in non-FIPS mode. As of MySQL 8.0.34, this option is deprecated. Expect it to be removed in a future version of MySQL. •**--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 6.3.2, “Encrypted Connection TLS Protocols and Ciphers”. This option was added in MySQL 8.0.16. •**--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 6.3.2, “Encrypted Connection TLS Protocols and Ciphers”. •**--user=user\_name**, **-u user\_name** The user name of the MySQL account to use for connecting to the server. •**--use-threads=N** Load files in parallel using *N* threads. •**--verbose**, **-v** Verbose mode. Print more information about what the program does. •**--version**, **-V** Display version information and exit. •**--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 4.2.8, “Connection Compression Control”. This option was added in MySQL 8.0.18. Here is a sample session that demonstrates use of **mysqlimport**: ``` $> mysql -e 'CREATE TABLE imptest(id INT, n VARCHAR(30))' test $> ed a 100 Max Sydow 101 Count Dracula . w imptest.txt 32 q $> od -c imptest.txt 0000000 1 0 0 \t M a x S y d o w \n 1 0 0000020 1 \t C o u n t D r a c u l a \n 0000040 $> mysqlimport --local test imptest.txt test.imptest: Records: 2 Deleted: 0 Skipped: 0 Warnings: 0 $> mysql -e 'SELECT * FROM imptest' test +------+---------------+ | id | n | +------+---------------+ | 100 | Max Sydow | | 101 | Count Dracula | +------+---------------+ ``` # [COPYRIGHT](#COPYRIGHT) Copyright © 1997, 2023, Oracle and/or its affiliates.
