mysqlimport

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.

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.

mysqldump supports the following options, which can be specified on the command line or in the [mysqldump] and [client] option file groups. mysqldump 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.

• --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.

• --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.

Here is a sample session that demonstrates use of mysqlimport:

shell> mysql -e ´CREATE TABLE imptest(id INT, n VARCHAR(30))´ test
shell> ed
a
100     Max Sydow
101     Count Dracula
.

shell> od -c imptest.txt

shell> mysqlimport --local test imptest.txt

shell> mysql -e ´SELECT * FROM imptest´ test
