mysqlimport - Unix, Linux Command
NAME
mysqlimport - a data import program
SYNOPSIS
Tag | Description |
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\(rq.
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.
For additional information about
mysqldump, see
Section 6.4, \(lqUsing mysqldump for Backups\(rq.
mysqlimport
supports the following options, which can be specified on the command line or in the
[mysqlimport]
and
[client]
option file groups.
mysqlimport
also supports the options for processing option files described at
Section 4.2.3.3.1, \(lqCommand-Line Options that Affect Option-File Handling\(rq.

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

MyISAM,
MEMORY, and
MERGE).
|

Tag | Description |
o

--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,
mysqlimport
prompts for one.
Specifying a password on the command line should be considered insecure. See
Section 5.3.2.2, \(lqEnd-User Guidelines for Password Security\(rq. You can use an option file to avoid giving the password on the command line.

Section 4.2.2, \(lqConnecting to the MySQL Server\(rq.
|
o
Tag | Description |
o
|
--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.
