MYSQLIMPORT(1) MySQL Database System MYSQLIMPORT(1)NAMEmysqlimport - a data import program
SYNOPSISmysqlimport [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
32

shell> od -c imptest.txt

0000020 1 \t C o u n t D r a c u l a \n
0000040
shell> mysqlimport--local test imptest.txt
test.imptest: Records: 2 Deleted: 0 Skipped: 0 Warnings: 0
shell> mysql -e 'SELECT * FROM imptest' test
+------+---------------+
