The mysqlimport client provides a
command-line interface to the
INFILE SQL statement. Most options to
mysqlimport correspond directly to clauses of
INFILE syntax. See Section 13.2.6, “LOAD DATA INFILE Syntax”.
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
patient all would be imported into a table
mysqlimport supports the following options,
which can be specified on the command line or in the
groups of an option file. For information about option files

This option is supported only in the version of mysqlimport that is supplied with MySQL Cluster. It is not available in standard MySQL Server 5.5 releases.
The directory where character sets are installed. See Section 10.5, “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

A hint about the client-side authentication plugin to use. See Section 6.3.6, “Pluggable Authentication”.
This option was added in MySQL 5.5.10.
Read this option file after the global option file but (on
Unix) before the user option file. If the file does not
exist or is otherwise inaccessible, an error occurs. Before
file_name must be
the full path name to the file. As of MySQL 5.5.8, the name
is interpreted relative to the current directory if given as
a relative path name.
Use only the given option file. If the file does not exist

file_name must be the full
path name to the file. As of MySQL 5.5.8, the name is
interpreted relative to the current directory if given as a

Read not only the usual option groups, but also groups with
the usual names and a suffix of

This affects only storage engines that use only table-level

to reading unknown options from an option file,

used to prevent them from being read.
The password to use when connecting to the server. If you

cannot have a space between the option
and the password. If you omit the
password value following the
-p option on the command line,
mysqlimport prompts for one.
Specifying a password on the command line should be considered insecure. See Section 184.108.40.206, “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 using a named pipe. This option applies only if the server supports named-pipe connections.
The directory in which to look for plugins. Specify this
option if the
--default-auth option is
used to specify an authentication plugin but
mysqlimport does not find it. See
Section 6.3.6, “Pluggable Authentication”.
This option was added in MySQL 5.5.10.
The TCP/IP port number to use for the connection.
Print the program name and all options that it gets from option files.
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”.
--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
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.
