MYSQLIMPORT(1)               MySQL Database System              MYSQLIMPORT(1)

NAME
       mysqlimport - a data import program

SYNOPSIS
       mysqlimport [options] db_name textfile1 ...

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 13.2.6, "LOAD DATA Statement".

       Invoke mysqlimport like this:

           shell> 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".

       o   --help, -?  Display a help message and exit.

       o   --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.

       o   --character-sets-dir=dir_name The directory where character sets
           are installed. See Section 10.15, "Character Set Configuration".

       o   --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.

       o   --compress, -C Compress all information sent between the client and
           the server if possible. See Section 4.2.6, "Connection Compression
           Control".

       o   --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.

       o   --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.

       o   --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.

       o   --default-character-set=charset_name Use charset_name as the
           default character set. See Section 10.15, "Character Set
           Configuration".

       o   --default-auth=plugin A hint about which client-side authentication
           plugin to use. See Section 6.2.13, "Pluggable Authentication".

       o   --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.  file_name is interpreted relative to the current directory
           if given as a relative path name rather than a full path name.

           For additional information about this and other option-file
           options, see Section 4.2.2.3, "Command-Line Options that Affect
           Option-File Handling".

       o   --defaults-file=file_name Use only the given option file. If the
           file does not exist or is otherwise inaccessible, an error occurs.
           file_name is interpreted relative to the current directory if given
           as a relative path name rather than a full path name.

           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".

       o   --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 the --defaults-group-suffix=_other option is given,
           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".

       o   --delete, -D Empty the table before importing the text file.

       o   --enable-cleartext-plugin Enable the mysql_clear_password cleartext
           authentication plugin. (See Section 6.4.1.6, "Client-Side Cleartext
           Pluggable Authentication".)

           This option was added in MySQL 5.7.10.

       o   --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 13.2.6, "LOAD DATA Statement".

       o   --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.

       o   --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 6.4.1.4, "Caching SHA-2 Pluggable Authentication".

           The --get-server-public-key option was added in MySQL 5.7.23.

       o   --host=host_name, -h host_name Import data to the MySQL server on
           the given host. The default host is localhost.

       o   --ignore, -i See the description for the --replace option.

       o   --ignore-lines=N Ignore the first N lines of the data file.

       o   --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 13.2.6, "LOAD DATA Statement".

       o   --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"

       o   --lock-tables, -l Lock all tables for writing before processing any
           text files. This ensures that all tables are synchronized on the
           server.

       o   --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).

           For additional information about this and other option-file
           options, see Section 4.2.2.3, "Command-Line Options that Affect
           Option-File Handling".

       o   --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).

       o   --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, if it exists, is read
           in all cases. This permits passwords to be specified in a safer way
           than on the command line even when --no-defaults is used.
           (.mylogin.cnf is created by the mysql_config_editor utility. See
           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".

       o   --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.

       o   --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.

       o   --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 6.2.13, "Pluggable Authentication".

       o   --port=port_num, -P port_num For TCP/IP connections, the port
           number to use.

       o   --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".

       o   --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 4.2.5, "Connection Transport Protocols".

       o   --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.

       o   --secure-auth Do not send passwords to the server in old (pre-4.1)
           format. This prevents connections except for servers that use the
           newer password format.

           As of MySQL 5.7.5, this option is deprecated;expect it to be
           removed in a future MySQL release. It is always enabled and
           attempting to disable it (--skip-secure-auth, --secure-auth=0)
           produces an error. Before MySQL 5.7.5, this option is enabled by
           default but can be disabled.

               Note
               Passwords that use the pre-4.1 hashing method are less secure
               than passwords that use the native password hashing method and
               should be avoided. Pre-4.1 passwords are deprecated and support
               for them was removed in MySQL 5.7.5. For account upgrade
               instructions, see Section 6.4.1.3, "Migrating Away from Pre-4.1
               Password Hashing and the mysql_old_password Plugin".

       o   --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 6.4.1.5, "SHA-256 Pluggable Authentication",
           and Section 6.4.1.4, "Caching SHA-2 Pluggable Authentication".

           The --server-public-key-path option was added in MySQL 5.7.23.

       o   --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.

       o   --silent, -s Silent mode. Produce output only when errors occur.

       o   --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.

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

       o   --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".

           This option was added in MySQL 5.7.10.

       o   --user=user_name, -u user_name The user name of the MySQL account
           to use for connecting to the server.

       o   --use-threads=N Load files in parallel using N threads.

       o   --verbose, -v Verbose mode. Print more information about what the
           program does.

       o   --version, -V Display version information and exit.

       Here is a sample session that demonstrates use of mysqlimport:
