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 13.2.6,
“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.
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 4.2.3.4, “Command-Line Options that
Affect Option-File Handling”.
•
--help, -?
Display a help
message and exit.
•
--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.
•
--character-sets-dir=path
The directory
where character sets are installed. See Section 10.5,
“Character Set Configuration”.
•
--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 10.5, “Character Set
Configuration”.
•
--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.
•
--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 13.2.6, “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 13.2.6, “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
(such as MyISAM, MEMORY, and 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, mysqlimport prompts for one.
Specifying a
password on the command line should be considered insecure.
See Section 6.1.2.1, “End-User Guidelines for
Password Security”. You can use an option file to
avoid giving the password on the command line.
•
--pipe, -W
On Windows,
connect to the server using a named pipe. This option
applies only if the server supports named-pipe
connections.
•
--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.
•
--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 permissible 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 using SSL and indicate where to find
SSL keys and certificates. See Section 6.3.8.4,
“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.
