mysqlimport - a data import program 


mysqlimport [options] db_name textfile1 ...


Themysqlimportclient provides a command-line interface to theLOAD DATA INFILESQL statement. Most options tomysqlimportcorrespond directly to clauses ofLOAD DATA INFILEsyntax. SeeSection 13.2.6, lqLOAD DATA INFILE Syntaxrq.

Invokemysqlimportlike this:

shell> mysqlimport [options] db_name textfile1 [textfile2 ...]

For each text file named on the command line,mysqlimportstrips 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 namedpatient.txt,patient.text, andpatientall would be imported into a table namedpatient.

mysqlimportsupports the following options, which can be specified on the command line or in the[mysqlimport]and[client]groups of an option file.mysqlimportalso supports the options for processing option files described atSection, lqCommand-Line Options that Affect Option-File Handlingrq.


Display a help message and exit.


On a computer having multiple network interfaces, this option can be used to select which interface is employed when connecting to the MySQL server.

This option is supported only in the version ofmysqlimportthat is supplied with MySQL Cluster, beginning with MySQL Cluster NDB 6.3.4. It is not available in standard MySQL 5.1 releases.


The directory where character sets are installed. SeeSection 10.5, lqCharacter Set Configurationrq.

*--columns=column_list,-c column_list

This option takes a comma-separated list of column names as its value. The order of the column names indicates how to match data file columns with table columns.


Compress all information sent between the client and the server if both support compression.

*--debug[=debug_options],-# [debug_options]

Write a debugging log. A typicaldebug_optionsstring is'd:t:o,file_name'. The default is'd:t:o'.


Print some debugging information when the program exits. This option was added in MySQL 5.1.21.


Print debugging information and memory and CPU usage statistics when the program exits. This option was added in MySQL 5.1.14.


Usecharset_nameas the default character set. SeeSection 10.5, lqCharacter Set Configurationrq.

Some options, such as--opt, automatically enable--lock-tables. If you want to override this, use--skip-lock-tablesat the end of the option list.


Empty the table before importing the text file.


These options have the same meaning as the corresponding clauses forLOAD DATA INFILE. SeeSection 13.2.6, lqLOAD DATA INFILE Syntaxrq.


Ignore errors. For example, if a table for a text file does not exist, continue processing any remaining files. Without--force,mysqlimportexits if a table does not exist.

*--host=host_name,-h host_name

Import data to the MySQL server on the given host. The default host islocalhost.


See the description for the--replaceoption.


Ignore the firstNlines of the data file.


This option has the same meaning as the corresponding clause forLOAD DATA INFILE. 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.) SeeSection 13.2.6, lqLOAD DATA INFILE Syntaxrq.


Read input files locally from the client host.


Lockalltables for writing before processing any text files. This ensures that all tables are synchronized on the server.


UseLOW_PRIORITYwhen loading the table. This affects only storage engines that use only table-level locking (such asMyISAM,MEMORY, andMERGE).


The password to use when connecting to the server. If you use the short option form (-p), youcannothave a space between the option and the password. If you omit thepasswordvalue following the--passwordor-poption on the command line,mysqlimportprompts for one.

Specifying a password on the command line should be considered insecure. SeeSection, lqEnd-User Guidelines for Password Securityrq. You can use an option file to avoid giving the password on the command line.


On Windows, connect to the server using a named pipe. This option applies only if the server supports named-pipe connections.

*--port=port_num,-P port_num

The TCP/IP port number to use for the connection.


The connection protocol to use for connecting to the server. It is useful when the other connection parameters normally would cause a protocol to be used other than the one you want. For details on the permissible values, seeSection 4.2.2, lqConnecting to the MySQL Serverrq.


The--replaceand--ignoreoptions 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.


Silent mode. Produce output only when errors occur.

*--socket=path,-S path

For connections tolocalhost, the Unix socket file to use, or, on Windows, the name of the named pipe to use.


Options that begin with--sslspecify whether to connect to the server using SSL and indicate where to find SSL keys and certificates. SeeSection, lqSSL Command Optionsrq.

*--user=user_name,-u user_name

The MySQL user name to use when connecting to the server.


Load files in parallel usingNthreads. This option was added in MySQL 5.1.7.


Verbose mode. Print more information about what the program does.


Display version information and exit.
