NAME¶
mysqlimport - a data import program
SYNOPSIS¶
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, “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
a
100 Max Sydow
101 Count Dracula
w imptest.txt

0000040
shell> mysqlimport --local test imptest.txt
test.imptest: Records: 2 Deleted: 0 Skipped: 0 Warnings: 0
shell> mysql -e 'SELECT * FROM imptest' test
+------+---------------+
