The mysqlimport client provides a command-line interface to the
LOAD DATA INFILESQL statement. Most options to mysqlimport correspond directly to clauses of
LOAD DATA INFILEsyntax. See Section 12.2.6, “
LOAD DATA INFILESyntax”.
Invoke mysqlimport like this:
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
patientall would be imported into a table named
mysqldump supports the following options, which can be specified on the command line or in the
[client]option file groups. mysqldump also supports the options for processing option files described at Section 126.96.36.199.1, “Command-Line Options that Affect Option-File Handling”.

The directory where character sets are installed. See Section 9.5, “Character Set Configuration”.
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.
Write a debugging log. A typical
'd:t:o,. The default is
Print some debugging information when the program exits. This option was added in MySQL 5.1.21.
Print debugging information and memory and CPU usage statistics when the program exits. This option was added in MySQL 5.1.14.

Empty the table before importing the text file.
Import data to the MySQL server on the given host. The default host is
See the description for the
Ignore the first
Nlines 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 12.2.6, “
LOAD DATA INFILESyntax”.
Read input files locally from the client host.

Lock all tables for writing before processing any text files. This ensures that all tables are synchronized on the server.
LOW_PRIORITYwhen loading the table. This affects only storage engines that use only table-level locking (such as
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
passwordvalue following the
-poption on the command line, mysqlimport prompts for one.
Specifying a password on the command line should be considered insecure. See Section 188.8.131.52, “End-User Guidelines for Password Security”. You can use an option file to avoid giving the password on the command line.
On Windows, connect to the server via a named pipe. This option applies only if the server supports named-pipe connections.
The TCP/IP port number to use for the connection.
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”.
--ignoreoptions 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.
The MySQL user name to use when connecting to the server.
Load files in parallel using
Nthreads. This option was added in MySQL 5.1.7.
Verbose mode. Print more information about what the program does.
Display version information and exit.
