NAME         top

       mariadb-import - a data import program (mysqlimport is now a
       symlink to mariadb-import)

SYNOPSIS         top

       mysqlimport [options] db_name textfile1 ...

DESCRIPTION         top

       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.

       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] option file groups.  mysqlimport also supports the
       options for processing option files.

       •   --help, -?

           Display a help message and exit.

       •   --character-sets-dir=path

           The directory where character sets are installed.

       •   --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, -C

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

       •   --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´.

       •   --debug-check

           Print some debugging information when the program exits.

       •   --debug-info

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

       •   --default-auth=plugin_name

           Default authentication client-side plugin to use.

       •   --default-character-set=charset_name

           Use charset_name as the default character set.

       •   --defaults-extra-file=filename

           Set filename as the file to read default options from after
           the global defaults files has been read.  Must be given as
           first option.

       •   --defaults-file=filename

           Set filename as the file to read default options from,
           override global defaults files.  Must be given as first

       •   --delete, -d

           Empty the table before importing the text file.

       •   --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 INFILE.

       •   --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.

       •   --host=host_name, -h host_name

           Import data to the MariaDB server on the given host. The
           default host is localhost.

       •   --ignore, -i

           See the description for the --replace option.

       •   --ignore-foreign-keys, -k

           Disable foreign key checks while importing the data.

       •   --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 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.).

       •   --local, -L

           Read input files locally from the client host.

       •   --lock-tables, -l

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

       •   --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 default options from any option file. This must
           be given as the first argument.

       •   --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
           considered insecure. You can use an option file to avoid
           giving the password on the command line.

       •   --pipe, -W

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

       •   --plugin-dir=name

            Directory for client-side plugins.

       •   --port=port_num, -P port_num

           The TCP/IP port number to use for the connection.  Forces
           --protocol=tcp when specified on the command line without
           other connection properties.

       •   --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

       •   --print-defaults

           Print the program argument list and exit.  This must be given
           as the first argument.

       •   --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.

       •   --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.  Forces
           --protocol=socket when specified on the command line without
           other connection properties; on Windows, forces

       •   --ssl

           Enable SSL for connection (automatically enabled with other
           flags). Disable with --skip-ssl.

       •   --ssl-ca=name

           CA file in PEM format (check OpenSSL docs, implies --ssl).

       •   --ssl-capath=name

           CA directory (check OpenSSL docs, implies --ssl).

       •   --ssl-cert=name

           X509 cert in PEM format (check OpenSSL docs, implies --ssl).

       •   --ssl-cipher=name

           SSL cipher to use (check OpenSSL docs, implies --ssl).

       •   --ssl-key=name

           X509 key in PEM format (check OpenSSL docs, implies --ssl).

       •   --ssl-crl=name

           Certificate revocation list (check OpenSSL docs, implies

       •   --ssl-crlpath=name

           Certificate revocation list path (check OpenSSL docs, implies

       •   --ssl-verify-server-cert

           Verify server's "Common Name" in its cert against hostname
           used when connecting. This option is disabled by default.

       •   --user=user_name, -u user_name

           The MariaDB user name to use when 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

       •   --version, -V

           Display version information and exit.

       Here is a sample session that demonstrates use of mysqlimport:

           shell> mysql -e ´CREATE TABLE imptest(id INT, n VARCHAR(30))´ test
           shell> ed
           100     Max Sydow
           101     Count Dracula
           w imptest.txt
           shell> 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
