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 13.2.5, “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 filename 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:
Display a help message and exit.
The directory where character sets are installed. See Section 5.10.1, “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 all information sent between the client and the server if both support compression.
--debug[=
, debug_options
]-# [
debug_options
]
Write a debugging log. The debug_options
string often is 'd:t:o,
.file_name
'
--default-character-set=
charset_name
Use charset_name
as the default character set. See Section 5.10.1, “The Character Set Used for Data and Sorting”.
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 13.2.5, “LOAD DATA INFILE
Syntax”.
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
.
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 13.2.5, “LOAD DATA INFILE
Syntax”.
Read input files locally from the client host.

, subscribe to the MySQL Network Monitoring and Advisory Service. For more information see http://www.mysql.com/products/enterprise/advisors.html.
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 (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 5.8.6, “Keeping Your Password Secure”.
The TCP/IP port number to use for the connection.
--protocol={TCP|SOCKET|PIPE|MEMORY}
The connection protocol to use.
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 mode. Produce output only when errors occur.
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 via SSL and indicate where to find SSL keys and certificates. See Section 5.8.7.3, “SSL Command Options”.
--user=
, user_name
-u
user_name
The MySQL username to use when connecting to the server.
Verbose mode. Print more information about what the program does.
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
