mysqlimport
MYSQLIMPORT(1) MySQL Database System MYSQLIMPORT(1)
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 SQL statement. Most options to mysqlimport correspond directly to
clauses of LOAD DATA syntax. See Section 15.2.9, "LOAD DATA Statement".
Invoke mysqlimport like this:
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 following options, which can be specified on
the command line or in the [mysqlimport] and [client] groups of an
option file. For information about option files used by MySQL programs,
see Section 6.2.2.2, "Using Option Files".

o --defaults-extra-file=file_name
+--------------------+-------------------+
|Command-Line Format | --defaults-extra- |
| | file=file_name |
+--------------------+-------------------+
|Type | File name |
+--------------------+-------------------+
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. If file_name is not an
absolute path name, it is interpreted relative to the current
directory.
For additional information about this and other option-file
options, see Section 6.2.2.3, "Command-Line Options that Affect
Option-File Handling".
o --defaults-file=file_name
+--------------------+---------------------------+
|Command-Line Format | --defaults-file=file_name |
+--------------------+---------------------------+
|Type | File name |
+--------------------+---------------------------+
Use only the given option file. If the file does not exist or is
otherwise inaccessible, an error occurs. If file_name is not an
absolute path name, it is interpreted relative to the current
directory.
Exception: Even with --defaults-file, client programs read
.mylogin.cnf.
For additional information about this and other option-file
options, see Section 6.2.2.3, "Command-Line Options that Affect
Option-File Handling".
o --defaults-group-suffix=str
+--------------------+-------------------+
|Command-Line Format | --defaults-group- |
| | suffix=str |
+--------------------+-------------------+
|Type | String |
+--------------------+-------------------+
Read not only the usual option groups, but also groups with the
usual names and a suffix of str. For example, mysqlimport normally
reads the [client] and [mysqlimport] groups. If this option is
given as --defaults-group-suffix=_other, mysqlimport also reads the
[client_other] and [mysqlimport_other] groups.
For additional information about this and other option-file
options, see Section 6.2.2.3, "Command-Line Options that Affect
Option-File Handling".
o --delete, -D

+--------------------+---------------------------+
|Type | Boolean |
+--------------------+---------------------------+
|Default Value | FALSE |
+--------------------+---------------------------+
Enable the mysql_clear_password cleartext authentication plugin.
(See Section 8.4.1.4, "Client-Side Cleartext Pluggable
Authentication".)
o --fields-terminated-by=..., --fields-enclosed-by=...,
--fields-optionally-enclosed-by=..., --fields-escaped-by=...
+--------------------+----------------------+
|Command-Line Format | --fields-terminated- |
| | by=string |
+--------------------+----------------------+
|Type | String |
+--------------------+----------------------+
+--------------------+--------------------+
|Command-Line Format | --fields-enclosed- |
| | by=string |
+--------------------+--------------------+
|Type | String |
+--------------------+--------------------+
+--------------------+----------------------+
|Command-Line Format | --fields-optionally- |
| | enclosed-by=string |
+--------------------+----------------------+
|Type | String |
+--------------------+----------------------+
+--------------------+---------------------+
|Command-Line Format | --fields-escaped-by |
+--------------------+---------------------+
|Type | String |
+--------------------+---------------------+
These options have the same meaning as the corresponding clauses
for LOAD DATA. See Section 15.2.9, "LOAD DATA Statement".
o --force, -f
+--------------------+---------+
|Command-Line Format | --force |
+--------------------+---------+
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.
o --get-server-public-key
+--------------------+-------------------------+
|Command-Line Format | --get-server-public-key |
+--------------------+-------------------------+
|Type | Boolean |
+--------------------+-------------------------+
Request from the server the public key required for RSA key
pair-based password exchange. This option applies to clients that
authenticate with the caching_sha2_password authentication plugin.
For that plugin, the server does not send the public key unless
requested. This option is ignored for accounts that do not
authenticate with that plugin. It is also ignored if RSA-based
password exchange is not used, as is the case when the client
connects to the server using a secure connection.
If --server-public-key-path=file_name is given and specifies a
valid public key file, it takes precedence over
--get-server-public-key.
For information about the caching_sha2_password plugin, see
Section 8.4.1.2, "Caching SHA-2 Pluggable Authentication".
o --host=host_name, -h host_name
+--------------------+------------------+
|Command-Line Format | --host=host_name |
+--------------------+------------------+
|Type | String |
+--------------------+------------------+
|Default Value | localhost |
+--------------------+------------------+
Import data to the MySQL server on the given host. The default host
is localhost.
o --ignore, -i
+--------------------+----------+
|Command-Line Format | --ignore |
+--------------------+----------+
See the description for the --replace option.
o --ignore-lines=N
+--------------------+------------------+
|Command-Line Format | --ignore-lines=# |
+--------------------+------------------+
|Type | Numeric |
+--------------------+------------------+
Ignore the first N lines of the data file.
o --lines-terminated-by=...
+--------------------+---------------------+
|Command-Line Format | --lines-terminated- |
| | by=string |
+--------------------+---------------------+
|Type | String |
+--------------------+---------------------+
This option has the same meaning as the corresponding clause for
LOAD DATA. 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 15.2.9, "LOAD DATA Statement".
o --local, -L
+--------------------+---------+
|Command-Line Format | --local |
+--------------------+---------+
|Type | Boolean |
+--------------------+---------+
|Default Value | FALSE |
+--------------------+---------+
By default, files are read by the server on the server host. With
this option, mysqlimport reads input files locally on the client
host.
Successful use of LOCAL load operations within mysqlimport also
requires that the server permits local loading; see Section 8.1.6,
"Security Considerations for LOAD DATA LOCAL"
o --lock-tables, -l
+--------------------+---------------+
|Command-Line Format | --lock-tables |
+--------------------+---------------+
Lock all tables for writing before processing any text files. This
ensures that all tables are synchronized on the server.
o --login-path=name
+--------------------+-------------------+
|Command-Line Format | --login-path=name |
+--------------------+-------------------+
|Type | String |
+--------------------+-------------------+
Read options from the named login path in the .mylogin.cnf login
path file. A "login path" is an option group containing options
that specify which MySQL server to connect to and which account to
authenticate as. To create or modify a login path file, use the
mysql_config_editor utility. See mysql_config_editor(1).
For additional information about this and other option-file
options, see Section 6.2.2.3, "Command-Line Options that Affect
Option-File Handling".
o --low-priority
+--------------------+----------------+
|Command-Line Format | --low-priority |
+--------------------+----------------+
Use LOW_PRIORITY when loading the table. This affects only storage
engines that use only table-level locking (such as MyISAM, MEMORY,
and MERGE).
o --no-defaults
+--------------------+---------------+
|Command-Line Format | --no-defaults |
+--------------------+---------------+
Do not read any option files. If program startup fails due to
reading unknown options from an option file, --no-defaults can be
used to prevent them from being read.
The exception is that the .mylogin.cnf file is read in all cases,
if it exists. This permits passwords to be specified in a safer way
than on the command line even when --no-defaults is used. To create
.mylogin.cnf, use the mysql_config_editor utility. See
mysql_config_editor(1).
For additional information about this and other option-file
options, see Section 6.2.2.3, "Command-Line Options that Affect
Option-File Handling".
o --password[=password], -p[password]
+--------------------+-----------------------+
|Command-Line Format | --password[=password] |
+--------------------+-----------------------+
|Type | String |
+--------------------+-----------------------+
The password of the MySQL account used for connecting to the
server. The password value is optional. If not given, mysqlimport
prompts for one. If given, there must be no space between
--password= or -p and the password following it. If no password
option is specified, the default is to send no password.
Specifying a password on the command line should be considered
insecure. To avoid giving the password on the command line, use an
option file. See Section 8.1.2.1, "End-User Guidelines for Password
Security".
To explicitly specify that there is no password and that
mysqlimport should not prompt for one, use the --skip-password
option.
o --password1[=pass_val] The password for multifactor authentication
factor 1 of the MySQL account used for connecting to the server.
The password value is optional. If not given, mysqlimport prompts
for one. If given, there must be no space between --password1= and
the password following it. If no password option is specified, the
default is to send no password.
Specifying a password on the command line should be considered
insecure. To avoid giving the password on the command line, use an
option file. See Section 8.1.2.1, "End-User Guidelines for Password
Security".
To explicitly specify that there is no password and that
mysqlimport should not prompt for one, use the --skip-password1
option.
--password1 and --password are synonymous, as are --skip-password1
and --skip-password.
o --password2[=pass_val] The password for multifactor authentication
factor 2 of the MySQL account used for connecting to the server.
The semantics of this option are similar to the semantics for
--password1; see the description of that option for details.
o --password3[=pass_val] The password for multifactor authentication
factor 3 of the MySQL account used for connecting to the server.
The semantics of this option are similar to the semantics for
--password1; see the description of that option for details.
o --pipe, -W
+--------------------+--------+
|Command-Line Format | --pipe |
+--------------------+--------+
|Type | String |
+--------------------+--------+
On Windows, connect to the server using a named pipe. This option
applies only if the server was started with the named_pipe system
variable enabled to support named-pipe connections. In addition,
the user making the connection must be a member of the Windows
group specified by the named_pipe_full_access_group system
variable.
o --plugin-dir=dir_name
+--------------------+-----------------------+
|Command-Line Format | --plugin-dir=dir_name |
+--------------------+-----------------------+
|Type | Directory name |
+--------------------+-----------------------+
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 8.2.17,
"Pluggable Authentication".
o --port=port_num, -P port_num
+--------------------+-----------------+
|Command-Line Format | --port=port_num |
+--------------------+-----------------+
|Type | Numeric |
+--------------------+-----------------+
|Default Value | 3306 |
+--------------------+-----------------+
For TCP/IP connections, the port number to use.
o --print-defaults
+--------------------+------------------+
|Command-Line Format | --print-defaults |
+--------------------+------------------+
Print the program name and all options that it gets from option
files.
For additional information about this and other option-file
options, see Section 6.2.2.3, "Command-Line Options that Affect
Option-File Handling".
o --protocol={TCP|SOCKET|PIPE|MEMORY}
+--------------------+-------------------+
|Command-Line Format | --protocol=type |
+--------------------+-------------------+
|Type | String |
+--------------------+-------------------+
|Default Value | [see text] |
+--------------------+-------------------+
|Valid Values | |
| | TCP |
| | |
| | SOCKET |
| | |
| | PIPE |
| | |
| | MEMORY |
+--------------------+-------------------+
The transport protocol to use for connecting to the server. It is
useful when the other connection parameters normally result in use
of a protocol other than the one you want. For details on the
permissible values, see Section 6.2.7, "Connection Transport
Protocols".
o --replace, -r
+--------------------+-----------+
|Command-Line Format | --replace |
+--------------------+-----------+
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.
o --server-public-key-path=file_name
+--------------------+----------------------+
|Command-Line Format | --server-public-key- |
| | path=file_name |
+--------------------+----------------------+
|Type | File name |
+--------------------+----------------------+
The path name to a file in PEM format containing a client-side copy
of the public key required by the server for RSA key pair-based
password exchange. This option applies to clients that authenticate
with the sha256_password or caching_sha2_password authentication
plugin. This option is ignored for accounts that do not
authenticate with one of those plugins. It is also ignored if
RSA-based password exchange is not used, as is the case when the
client connects to the server using a secure connection.
If --server-public-key-path=file_name is given and specifies a
valid public key file, it takes precedence over
--get-server-public-key.
For sha256_password, this option applies only if MySQL was built
using OpenSSL.
For information about the sha256_password and caching_sha2_password
plugins, see Section 8.4.1.3, "SHA-256 Pluggable Authentication",
and Section 8.4.1.2, "Caching SHA-2 Pluggable Authentication".
o --shared-memory-base-name=name
+--------------------+-----------------------+
|Command-Line Format | --shared-memory-base- |
| | name=name |
+--------------------+-----------------------+
|Platform Specific | Windows |
+--------------------+-----------------------+
On Windows, the shared-memory name to use for connections made
using shared memory to a local server. The default value is MYSQL.
The shared-memory name is case-sensitive.
This option applies only if the server was started with the
shared_memory system variable enabled to support shared-memory
connections.
o --silent, -s
+--------------------+----------+
|Command-Line Format | --silent |
+--------------------+----------+
Silent mode. Produce output only when errors occur.
o --socket=path, -S path
+--------------------+--------------------------------+
|Command-Line Format | --socket={file_name|pipe_name} |
+--------------------+--------------------------------+
|Type | String |
+--------------------+--------------------------------+
For connections to localhost, the Unix socket file to use, or, on
Windows, the name of the named pipe to use.
On Windows, this option applies only if the server was started with
the named_pipe system variable enabled to support named-pipe
connections. In addition, the user making the connection must be a
member of the Windows group specified by the
named_pipe_full_access_group system variable.
o --ssl* Options that begin with --ssl specify whether to connect to
the server using encryption and indicate where to find SSL keys and
certificates. See the section called "Command Options for Encrypted
Connections".
o --ssl-fips-mode={OFF|ON|STRICT}
+--------------------+----------------------+
|Command-Line Format | --ssl-fips- |
| | mode={OFF|ON|STRICT} |
+--------------------+----------------------+
|Deprecated | 8.0.34 |
+--------------------+----------------------+
|Type | Enumeration |
+--------------------+----------------------+
|Default Value | OFF |
+--------------------+----------------------+
|Valid Values | |
| | OFF |
| | |
| | ON |
| | |
| | STRICT |
+--------------------+----------------------+
Controls whether to enable FIPS mode on the client side. The
--ssl-fips-mode option differs from other --ssl-xxx options in that
it is not used to establish encrypted connections, but rather to
affect which cryptographic operations to permit. See Section 8.8,
"FIPS Support".
These --ssl-fips-mode values are permitted:
o OFF: Disable FIPS mode.
o ON: Enable FIPS mode.
o STRICT: Enable "strict" FIPS mode.
Note
If the OpenSSL FIPS Object Module is not available, the only
permitted value for --ssl-fips-mode is OFF. In this case,
setting --ssl-fips-mode to ON or STRICT causes the client to
produce a warning at startup and to operate in non-FIPS mode.
As of MySQL 8.0.34, this option is deprecated. Expect it to be
removed in a future version of MySQL.
o --tls-ciphersuites=ciphersuite_list
+--------------------+-------------------------------+
|Command-Line Format | --tls- |
| | ciphersuites=ciphersuite_list |
+--------------------+-------------------------------+
|Introduced | 8.0.16 |
+--------------------+-------------------------------+
|Type | String |
+--------------------+-------------------------------+
The permissible ciphersuites for encrypted connections that use
TLSv1.3. The value is a list of one or more colon-separated
ciphersuite names. The ciphersuites that can be named for this
option depend on the SSL library used to compile MySQL. For
details, see Section 8.3.2, "Encrypted Connection TLS Protocols and
Ciphers".
This option was added in MySQL 8.0.16.
o --tls-version=protocol_list
+--------------------------+------------------------------------------+
|Command-Line Format | --tls- |
| | version=protocol_list |
+--------------------------+------------------------------------------+
|Type | String |
+--------------------------+------------------------------------------+
|Default Value (>= 8.0.16) | |
| | TLSv1,TLSv1.1,TLSv1.2,TLSv1.3 |
| | (OpenSSL 1.1.1 |
| | or higher) |
| | |
| | TLSv1,TLSv1.1,TLSv1.2 |
| | (otherwise) |
+--------------------------+------------------------------------------+
|Default Value (<= 8.0.15) | TLSv1,TLSv1.1,TLSv1.2 |
+--------------------------+------------------------------------------+
The permissible TLS protocols for encrypted connections. The value
is a list of one or more comma-separated protocol names. The
protocols that can be named for this option depend on the SSL
library used to compile MySQL. For details, see Section 8.3.2,
"Encrypted Connection TLS Protocols and Ciphers".
o --user=user_name, -u user_name
+--------------------+-------------------+
|Command-Line Format | --user=user_name, |
+--------------------+-------------------+
|Type | String |
+--------------------+-------------------+
The user name of the MySQL account to use for connecting to the
server.

o --zstd-compression-level=level
+--------------------+----------------------------+
|Command-Line Format | --zstd-compression-level=# |
+--------------------+----------------------------+
|Introduced | 8.0.18 |
+--------------------+----------------------------+
|Type | Integer |
+--------------------+----------------------------+
The compression level to use for connections to the server that use
the zstd compression algorithm. The permitted levels are from 1 to
22, with larger values indicating increasing levels of compression.
The default zstd compression level is 3. The compression level
setting has no effect on connections that do not use zstd
compression.
For more information, see Section 6.2.8, "Connection Compression
Control".
This option was added in MySQL 8.0.18.
