MARIADB-IMPORT(1)

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

SYNOPSIS

mariadb-import [options] db_name textfile1 ...

DESCRIPTION

The mariadb-import client provides a command-line interface to the LOAD DATA INFILE SQL statement. Most options to mariadb-import correspond directly to clauses of LOAD DATA INFILE syntax.

Invoke mariadb-import like this:

    shell> mariadb-import [options] db_name textfile1 [textfile2 ...]

For each text file named on the command line, mariadb-import 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.

mariadb-import supports the following options, which can be specified on the command line or in the [mariadb-import] and [client] option file groups. mariadb-import 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 option.

    • --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, mariadb-import 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.

    • --innodb-optimize-keys

    Create secondary indexes after data load, which speeds up loading (InnoDB only). Defaults to on; use --skip-innodb-optimize-keys to disable.

    • --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.

    • --parallel=N, -j N

    Number of LOAD DATA jobs executed in parallel. --use-threads is a synonym.

    • --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, mariadb-import 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 connections.

    • --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 want.

    • --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 --protocol=pipe.

    • --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).

    • --ssl-crlpath=name

    Certificate revocation list path (check OpenSSL docs, implies --ssl).

    • --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. Synonym for -j, --parallel=num

    • --verbose, -v

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

    • --version, -V

    Display version information and exit.

Here is a sample session that demonstrates use of mariadb-import:
