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”.

├────────────────────┼─────────────────────────────┤
│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”.

┌────────────────────┬─────────────────────┐
│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”.
• --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.
• --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”.
• --host=host_name, -h host_name
┌────────────────────┬──────────────────┐
│Command-Line Format │ --host=host_name │
├────────────────────┼──────────────────┤
│Type │ String │
├────────────────────┼──────────────────┤

│Type │ Numeric │
└────────────────────┴──────────────────┘
Ignore the first N lines of the data file.
• --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”.
• --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”
• --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.
• --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”.
• --no-login-paths
┌────────────────────┬──────────────────┐
│Command-Line Format │ --no-login-paths │
└────────────────────┴──────────────────┘
Skips reading options from the login path file.
See --login-path for related information.
For additional information about this and other option-file options, see
Section 6.2.2.3, “Command-Line Options that Affect Option-File Handling”.
• --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).
• --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”.
• --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.
• --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.
• --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.
• --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.
• --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.
• --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”.
• --port=port_num, -P port_num
┌────────────────────┬─────────────────┐
│Command-Line Format │ --port=port_num │
├────────────────────┼─────────────────┤

├────────────────────┼─────────────────┤
│Default Value │ 3306 │
└────────────────────┴─────────────────┘
For TCP/IP connections, the port number to use.
• --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”.
• --protocol={TCP|SOCKET|PIPE|MEMORY}
┌────────────────────┬───────────────────┐
│Command-Line Format │ --protocol=type │
├────────────────────┼───────────────────┤

├────────────────────┼───────────────────┤
│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”.
• --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.
• --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 (deprecated) 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 (deprecated), 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”.
• --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.
• --silent, -s
┌────────────────────┬──────────┐
│Command-Line Format │ --silent │
└────────────────────┴──────────┘
Silent mode. Produce output only when errors occur.
• --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.
• --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”.
• --ssl-fips-mode={OFF|ON|STRICT}
┌────────────────────┬─────────────────────────────────┐
│Command-Line Format │ --ssl-fips-mode={OFF|ON|STRICT} │
├────────────────────┼─────────────────────────────────┤

│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:
• OFF: Disable FIPS mode.
• ON: Enable FIPS mode.
• 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.
This option is deprecated. Expect it to be removed in a future version of MySQL.
• --tls-ciphersuites=ciphersuite_list

├────────────────────┼───────────────────────────────┤
│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”.
• --tls-sni-servername=server_name
┌────────────────────┬──────────────────────────────────┐
│Command-Line Format │ --tls-sni-servername=server_name │
├────────────────────┼──────────────────────────────────┤
│Type │ String │
└────────────────────┴──────────────────────────────────┘
When specified, the name is passed to the libmysqlclient C API library using the
MYSQL_OPT_TLS_SNI_SERVERNAME option of mysql_options(). The server name is not
case-sensitive. To show which server name the client specified for the current
session, if any, check the Tls_sni_server_name status variable.
Server Name Indication (SNI) is an extension to the TLS protocol (OpenSSL must be
compiled using TLS extensions for this option to function). The MySQL implementation
of SNI represents the client-side only.
