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.
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.
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,.
The default is file_name''d:t:o'.
--default-character-set=
charset_name
Use charset_name as the default
character set. See Section 10.5, “Character Set Configuration”.
--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 the first N lines of the
data file.
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.
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.
--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.
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 6.3.6.4, “SSL Command Options”.
--user=,
user_name-u
user_name
The MySQL user name to use when connecting to the server.
--verbose,
-v
Verbose mode. Print more information about what the program does.
--version,
-V
Display version information and exit.
Some options, such as
--opt, automatically
enable --lock-tables. If you want to
override this, use --skip-lock-tables at
the end of the option list.
