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 13.2.9, "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 4.2.2.2, "Using Option Files".
o --help, -? Display a help message and exit.
o --bind-address=ip_address On a computer having multiple network
interfaces, use this option to select which interface to use for
connecting to the MySQL server.
o --character-sets-dir=dir_name The directory where character sets
are installed. See Section 10.15, "Character Set Configuration".
o --columns=column_list, -c column_list This option takes a list of
comma-separated column names as its value. The order of the column
names indicates how to match data file columns with table columns.
o --compress, -C Compress all information sent between the client and
the server if possible. See Section 4.2.8, "Connection Compression
Control".
As of MySQL 8.0.18, this option is deprecated. Expect it to be
removed in a future version of MySQL. See the section called
"Configuring Legacy Connection Compression".
o --compression-algorithms=value The permitted compression algorithms
for connections to the server. The available algorithms are the
same as for the protocol_compression_algorithms system variable.
The default value is uncompressed.
For more information, see Section 4.2.8, "Connection Compression
Control".
This option was added in MySQL 8.0.18.
o --debug[=debug_options], -# [debug_options] Write a debugging log.
A typical debug_options string is d:t:o,file_name. The default is
d:t:o.
This option is available only if MySQL was built using WITH_DEBUG.
MySQL release binaries provided by Oracle are not built using this
option.
o --debug-check Print some debugging information when the program
exits.
This option is available only if MySQL was built using WITH_DEBUG.
MySQL release binaries provided by Oracle are not built using this
option.
o --debug-info Print debugging information and memory and CPU usage
statistics when the program exits.
This option is available only if MySQL was built using WITH_DEBUG.
MySQL release binaries provided by Oracle are not built using this
option.
o --default-character-set=charset_name Use charset_name as the
default character set. See Section 10.15, "Character Set
Configuration".
o --default-auth=plugin A hint about which client-side authentication
plugin to use. See Section 6.2.17, "Pluggable Authentication".
o --defaults-extra-file=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 4.2.2.3, "Command-Line Options that Affect
Option-File Handling".
o --defaults-file=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 4.2.2.3, "Command-Line Options that Affect
Option-File Handling".
o --defaults-group-suffix=str 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 4.2.2.3, "Command-Line Options that Affect
Option-File Handling".
o --delete, -D Empty the table before importing the text file.
o --enable-cleartext-plugin Enable the mysql_clear_password cleartext
authentication plugin. (See Section 6.4.1.4, "Client-Side Cleartext
Pluggable Authentication".)
o --fields-terminated-by=..., --fields-enclosed-by=...,
--fields-optionally-enclosed-by=..., --fields-escaped-by=... These
options have the same meaning as the corresponding clauses for LOAD
DATA. See Section 13.2.9, "LOAD DATA Statement".
o --force, -f 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 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 6.4.1.2, "Caching SHA-2 Pluggable Authentication".
o --host=host_name, -h host_name Import data to the MySQL server on
the given host. The default host is localhost.
o --ignore, -i See the description for the --replace option.
o --ignore-lines=N Ignore the first N lines of the data file.
o --lines-terminated-by=... 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 13.2.9, "LOAD DATA Statement".
o --local, -L 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 6.1.6,
"Security Considerations for LOAD DATA LOCAL"
o --lock-tables, -l Lock all tables for writing before processing any
text files. This ensures that all tables are synchronized on the
server.
o --login-path=name 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 4.2.2.3, "Command-Line Options that Affect
Option-File Handling".
o --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 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 4.2.2.3, "Command-Line Options that Affect
Option-File Handling".
o --password[=password], -p[password] 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 6.1.2.1, "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 6.1.2.1, "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 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 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 6.2.17, "Pluggable Authentication".
o --port=port_num, -P port_num For TCP/IP connections, the port
number to use.
o --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 4.2.2.3, "Command-Line Options that Affect
Option-File Handling".
o --protocol={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 4.2.7, "Connection Transport Protocols".
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.
o --server-public-key-path=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 6.4.1.3, "SHA-256 Pluggable Authentication",
and Section 6.4.1.2, "Caching SHA-2 Pluggable Authentication".
o --shared-memory-base-name=name 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 Silent mode. Produce output only when errors occur.
o --socket=path, -S path 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} 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 6.8, "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 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 6.3.2, "Encrypted
Connection TLS Protocols and Ciphers".
This option was added in MySQL 8.0.16.
o --tls-version=protocol_list 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 6.3.2, "Encrypted Connection TLS Protocols and
Ciphers".
o --user=user_name, -u user_name The user name of the MySQL account
to use for connecting to the server.
o --use-threads=N Load files in parallel using N threads.
o --verbose, -v Verbose mode. Print more information about what the
program does.
o --version, -V Display version information and exit.
o --zstd-compression-level=level 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 4.2.8, "Connection Compression
Control".
This option was added in MySQL 8.0.18.
