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 INFILE SQL
statement. Most options to mysqlimport correspond directly to clauses of LOAD DATA INFILE
syntax. See Section 13.2.6, "LOAD DATA INFILE Syntax".
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.
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 4.2.6, "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 10.14, "Character Set
Configuration".
o --columns=column_list, -c column_list
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.
o --compress, -C
Compress all information sent between the client and the server if both support
compression.
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.
o --debug-check
Print some debugging information when the program exits.
o --debug-info
Print debugging information and memory and CPU usage statistics when the program
exits.
o --default-character-set=charset_name
Use charset_name as the default character set. See Section 10.14, "Character Set
Configuration".
o --default-auth=plugin
A hint about the client-side authentication plugin to use. See Section 6.3.9,
"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.
file_name is interpreted relative to the current directory if given as a relative path
name rather than a full path name.
o --defaults-file=file_name
Use only the given option file. If the file does not exist or is otherwise
inaccessible, an error occurs. file_name is interpreted relative to the current
directory if given as a relative path name rather than a full path name.
Exception: Even with --defaults-file, client programs read .mylogin.cnf.
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 the --defaults-group-suffix=_other option is given, mysqlimport also reads
the [client_other] and [mysqlimport_other] groups.
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 6.5.1.6,
"Client-Side Cleartext Pluggable Authentication".)
This option was added in MySQL 5.7.10.
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 INFILE.
See Section 13.2.6, "LOAD DATA INFILE Syntax".
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 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 6.5.1.5, "Caching
SHA-2 Pluggable Authentication".
The --get-server-public-key option was added in MySQL 5.7.23.
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 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
Section 13.2.6, "LOAD DATA INFILE Syntax".
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. Enabling local data loading
also requires that the server permits it; see Section 6.1.6, "Security Issues with
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).
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, if it exists, is read in all cases. This
permits passwords to be specified in a safer way than on the command line even when
--no-defaults is used. (.mylogin.cnf is created by the mysql_config_editor utility.
See mysql_config_editor(1).)
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 6.1.2.1, "End-User Guidelines for Password Security". You can use an option
file to avoid giving the password on the command line.
o --pipe, -W
On Windows, connect to the server using a named pipe. This option applies only if the
server supports named-pipe connections.
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 6.3.9, "Pluggable Authentication".
o --port=port_num, -P port_num
The TCP/IP port number to use for the connection.
o --print-defaults
Print the program name and all options that it gets from option files.
o --protocol={TCP|SOCKET|PIPE|MEMORY}
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".
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 --secure-auth
Do not send passwords to the server in old (pre-4.1) format. This prevents connections
except for servers that use the newer password format.
As of MySQL 5.7.5, this option is deprecated and will be removed in a future MySQL
release. It is always enabled and attempting to disable it (--skip-secure-auth,
--secure-auth=0) produces an error. Before MySQL 5.7.5, this option is enabled by
default but can be disabled.
Note
Passwords that use the pre-4.1 hashing method are less secure than passwords that
use the native password hashing method and should be avoided. Pre-4.1 passwords
are deprecated and support for them was removed in MySQL 5.7.5. For account
upgrade instructions, see Section 6.5.1.3, "Migrating Away from Pre-4.1 Password
Hashing and the mysql_old_password Plugin".
o --server-public-key-path=file_name
The path name to a file containing a client-side copy of the public key required by
the server for RSA key pair-based password exchange. The file must be in PEM format.
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 6.5.1.4, "SHA-256 Pluggable Authentication", and Section 6.5.1.5, "Caching
SHA-2 Pluggable Authentication".
The --server-public-key-path option was added in MySQL 5.7.23.
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.
The server must be started with the --shared-memory option to enable 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.
o --ssl*
Options that begin with --ssl specify whether to connect to the server using SSL and
indicate where to find SSL keys and certificates. See Section 6.4.2, "Command Options
for Encrypted Connections".
o --tls-version=protocol_list
The protocols permitted by the client for encrypted connections. The value is a
comma-separated list containing one or more protocol names. The protocols that can be
named for this option depend on the SSL library used to compile MySQL. For details,
see Section 6.4.6, "Encrypted Connection Protocols and Ciphers".
This option was added in MySQL 5.7.10.
o --user=user_name, -u user_name
The MySQL user name to use when 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.
