drizzleimport1

A data import program

Usage

mysqlimport [options] db_name textfile1 ...

Overview

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, “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 options in the following list. It also reads option files and supports the options for processing them described at Section 4.2.3.2.1, “Command-Line Options that Affect Option-File Handling”.

•

--help, -?

Display a help message and exit.

•

--character-sets-dir=path

The directory where character sets are installed. See Section 9.2, “The Character Set Used for Data and Sorting”.

•

--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-character-set=charset_name

Use charset_name as the default character set. See Section 9.2, “The Character Set Used for Data and Sorting”.

•

--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. See Section 12.2.6, “LOAD DATA INFILE Syntax”.

•

--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 MySQL server on the given host. The default host is localhost.

•

--ignore, -i

See the description for the --replace option.

•

--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.) See Section 12.2.6, “LOAD DATA INFILE Syntax”.

•

--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 (MyISAM, MEMORY, MERGE).

•

--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, you are prompted for one.

Specifying a password on the command line should be considered insecure. See Section 5.5.6.2, “End-User Guidelines for Password Security”.

•

--pipe, -W

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

•

--port=port_num, -P port_num

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

•

--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 allowable values, see Section 4.2.2, “Connecting to the MySQL Server”.

•

--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.

•

--ssl*

Options that begin with --ssl specify whether to connect to the server via SSL and indicate where to find SSL keys and certificates. See Section 5.5.7.3, “SSL Command Options”.

•

--user=user_name, -u user_name

The MySQL 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 does.

•

--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

shell> mysql -e 'SELECT * FROM imptest' test
