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.
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] option file groups. mysqlimport also supports the
options for processing option files.
• --help, -?
Display a help message and exit.
• --character-sets-dir=path
The directory where character sets are installed.
• --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.
• --compress, -C
Compress all information sent between the client and the
server if both support compression.
• --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´.
• --debug-check
Print some debugging information when the program exits.
• --debug-info
Print debugging information and memory and CPU usage
statistics when the program exits.
• --default-auth=plugin_name
Default authentication client-side plugin to use.
• --default-character-set=charset_name
Use charset_name as the default character set.
• --defaults-extra-file=filename
Set filename as the file to read default options from after
the global defaults files has been read. Must be given as
first option.
• --defaults-file=filename
Set filename as the file to read default options from,
override global defaults files. Must be given as first
option.
• --delete, -d
Empty the table before importing the text file.
• --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.
• --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.
• --host=host_name, -h host_name
Import data to the MariaDB server on the given host. The
default host is localhost.
• --ignore, -i
See the description for the --replace option.
• --ignore-foreign-keys, -k
Disable foreign key checks while importing the data.
• --ignore-lines=N
Ignore the first N lines of the data file.
• --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.).
• --local, -L
Read input files locally from the client host.
• --lock-tables, -l
Lock all tables for writing before processing any text files.
This ensures that all tables are synchronized on the server.
• --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
Do not read default options from any option file. This must
be given as the first argument.
• --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. You can use an option file to avoid
giving the password on the command line.
• --pipe, -W
On Windows, connect to the server via a named pipe. This
option applies only if the server supports named-pipe
connections.
• --plugin-dir=name
Directory for client-side plugins.
• --port=port_num, -P port_num
The TCP/IP port number to use for the connection. Forces
--protocol=tcp when specified on the command line without
other connection properties.
• --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.
• --print-defaults
Print the program argument list and exit. This must be given
as the first argument.
• --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.
• --silent, -s
Silent mode. Produce output only when errors occur.
• --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. Forces
--protocol=socket when specified on the command line without
other connection properties; on Windows, forces
--protocol=pipe.
• --ssl
Enable SSL for connection (automatically enabled with other
flags). Disable with --skip-ssl.
• --ssl-ca=name
CA file in PEM format (check OpenSSL docs, implies --ssl).
• --ssl-capath=name
CA directory (check OpenSSL docs, implies --ssl).
• --ssl-cert=name
X509 cert in PEM format (check OpenSSL docs, implies --ssl).
• --ssl-cipher=name
SSL cipher to use (check OpenSSL docs, implies --ssl).
• --ssl-key=name
X509 key in PEM format (check OpenSSL docs, implies --ssl).
• --ssl-crl=name
Certificate revocation list (check OpenSSL docs, implies
--ssl).
• --ssl-crlpath=name
Certificate revocation list path (check OpenSSL docs, implies
--ssl).
• --ssl-verify-server-cert
Verify server's "Common Name" in its cert against hostname
used when connecting. This option is disabled by default.
• --user=user_name, -u user_name
The MariaDB user name to use when connecting to the server.
• --use-threads=N
Load files in parallel using N threads.
• --verbose, -v
Verbose mode. Print more information about what the program
does.
• --version, -V
Display version information and exit.
