     mysqlimport - a data import program

     mysqlimport [options] db_name textfile1 ...

     The mysqlimport client provides a command-line interface to
     the LOAD DATA INFILE SQL statement. Most options to
     mysqlimport correspond directly to clauses of LOAD DATA
     INFILE syntax. See Section 13.2.6, "LOAD DATA INFILE

     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.

     For additional information about mysqldump, see Section 7.4,
     "Using mysqldump for Backups".

     mysqlimport supports the following options, which can be
     specified on the command line or in the [mysqlimport] and
     [client] groups of an option file.  mysqlimport also
     supports the options for processing option files described
     at Section, "Command-Line Options that Affect
     Option-File Handling".

     o   --help, -?

         Display a help message and exit.

     o   --bind-address=ip_address

         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 of
         mysqlimport that is supplied with MySQL Cluster. It is
         not available in standard MySQL Server 5.5 releases.

     o   --character-sets-dir=path

         The directory where character sets are installed. See
         Section 10.5, "Character Set Configuration".

MySQL 5.5            Last change: 03/22/2013                    1

MySQL Database System                              MYSQLIMPORT(1)

     o   --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.

     o   --compress, -C

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

     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'.

     o   --debug-check

         Print some debugging information when the program exits.

     o   --debug-info

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

     o   --default-character-set=charset_name

         Use charset_name as the default character set. See
         Section 10.5, "Character Set Configuration".

     o   --default-auth=plugin

         The client-side authentication plugin to use. See
         Section 6.3.6, "Pluggable Authentication".

         This option was added in MySQL 5.5.10.

     o   --delete, -D

         Empty the table before importing the text file.

     o   --fields-terminated-by=..., --fields-enclosed-by=...,

         These options have the same meaning as the corresponding
         clauses for LOAD DATA INFILE. See Section 13.2.6, "LOAD
         DATA INFILE Syntax".

     o   --force, -f

         Ignore errors. For example, if a table for a text file

MySQL 5.5            Last change: 03/22/2013                    2

MySQL Database System                              MYSQLIMPORT(1)

         does not exist, continue processing any remaining files.
         Without --force, mysqlimport exits if a table does not

     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 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.)
         See Section 13.2.6, "LOAD DATA INFILE Syntax".

     o   --local, -L

         Read input files locally from the client host.

     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   --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   --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, mysqlimport prompts for one.

         Specifying a password on the command line should be

MySQL Database System                              MYSQLIMPORT(1)

         considered insecure. See Section, "End-User
         Guidelines for Password Security". You can use an option
         file to avoid giving the password on the command line.

     o   --pipe, -W

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

     o   --plugin-dir=path

         The directory in which to look for plugins. It may be
         necessary to specify this option if the --default-auth
         option is used to specify an authentication plugin but
         mysqlimport does not find it. See Section 6.3.6,
         "Pluggable Authentication".

         This option was added in MySQL 5.5.10.

     o   --port=port_num, -P port_num

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

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

         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, see Section 4.2.2, "Connecting to
         the MySQL Server".

     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   --silent, -s

         Silent mode. Produce output only when errors occur.

     o   --socket=path, -S path

         For connections to localhost, the Unix socket file to

MySQL Database System                              MYSQLIMPORT(1)

         use, or, on Windows, the name of the named pipe to use.

     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 Section, "SSL Command

     o   --user=user_name, -u user_name

         The MySQL user name to use when connecting to the

     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
