mysqlimport - Unix, Linux Command



NAME

mysqlimport - a data import program

SYNOPSIS

Tag Description
mysqlimport [options] db_name textfile1 ...

DESCRIPTION

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 12.2.6, \(lqLOAD DATA INFILE Syntax\(rq.

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 6.4, \(lqUsing mysqldump for Backups\(rq.

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 described at Section 4.2.3.3.1, \(lqCommand-Line Options that Affect Option-File Handling\(rq.

o

Tag Description
o --help, -?

Display a help message and exit.

o

Tag Description
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, beginning with MySQL Cluster NDB 6.3.4. It is not available in standard MySQL 5.1 releases.

o

Tag Description
o --character-sets-dir=path

The directory where character sets are installed. See Section 9.5, \(lqCharacter Set Configuration\(rq.

o

Tag Description
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

Tag Description
o --compress, -C

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

o

Tag Description
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

Tag Description
o --debug-check

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

o

Tag Description
o --debug-info

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

o

Tag Description
o --default-character-set=charset_name

Use charset_name as the default character set. See Section 9.5, \(lqCharacter Set Configuration\(rq.

o

Tag Description
o --delete, -D

Empty the table before importing the text file.

o

Tag Description
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 INFILE. See Section 12.2.6, \(lqLOAD DATA INFILE Syntax\(rq.

o

Tag Description
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

Tag Description
o --host=host_name, -h host_name

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

o

Tag Description
o --ignore, -i

See the description for the --replace option.

o

Tag Description
o --ignore-lines=N

Ignore the first N lines of the data file.

o

Tag Description
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 12.2.6, \(lqLOAD DATA INFILE Syntax\(rq.

o

Tag Description
o --local, -L

Read input files locally from the client host.

o

Tag Description
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

Tag Description
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

Tag Description
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 considered insecure. See Section 5.3.2.2, \(lqEnd-User Guidelines for Password Security\(rq. You can use an option file to avoid giving the password on the command line.

o

Tag Description
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

Tag Description
o --port=port_num, -P port_num

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

o

Tag Description
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, \(lqConnecting to the MySQL Server\(rq.

o

Tag Description
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

Tag Description
o --silent, -s

Silent mode. Produce output only when errors occur.

o

Tag Description
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.

o

Tag Description
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 5.5.6.3, \(lqSSL Command Options\(rq.

o

Tag Description
o --user=user_name, -u user_name

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

o

Tag Description
o --use-threads=N

Load files in parallel using N threads. This option was added in MySQL 5.1.7.

o

Tag Description
o --verbose, -v

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

o

Tag Description
o --version, -V

Display version information and exit.

Here is a sample session that demonstrates use of mysqlimport:

shell> ed

100     Max Sydow
101     Count Dracula
