Dumping structure and contents of MySQL databases and tables.

Usage: mysqldump [OPTIONS] database [tables]

OR     mysqldump [OPTIONS] --databases [OPTIONS] DB1 [DB2 DB3...]

OR     mysqldump [OPTIONS] --all-databases [OPTIONS]

 

Default options are read from the following files in the given order:

C:/WINDOWS/my.ini C:/WINDOWS/my.cnf C:/my.ini C:/my.cnf E:/Soft/Programs/MySQL/MySQL Server 5.6/my.ini E:/Soft/Programs/MySQL/MySQL Server 5.6/my.cnf 

The following groups are read: mysqldump client

The following options may be given as the first argument:

--print-defaults        Print the program argument list and exit.

--no-defaults           Don't read default options from any option file,

                        except for login file.

--defaults-file=#       Only read default options from the given file #.

--defaults-extra-file=# Read this file after the global files are read.

--defaults-group-suffix=#

                        Also read groups with concat(group, suffix)

--login-path=#          Read this path from the login file.

  -A, --all-databases Dump all the databases. This will be same as --databases

                      with all databases selected.

  -Y, --all-tablespaces 

                      Dump all the tablespaces.

  -y, --no-tablespaces 

                      Do not dump any tablespace information.

  --add-drop-database Add a DROP DATABASE before each create.

  --add-drop-table    Add a DROP TABLE before each create.

                      (Defaults to on; use --skip-add-drop-table to disable.)

  --add-drop-trigger  Add a DROP TRIGGER before each create.

  --add-locks         Add locks around INSERT statements.

                      (Defaults to on; use --skip-add-locks to disable.)

  --allow-keywords    Allow creation of column names that are keywords.

  --apply-slave-statements 

                      Adds 'STOP SLAVE' prior to 'CHANGE MASTER' and 'START

                      SLAVE' to bottom of dump.

  --bind-address=name IP address to bind to.

  --character-sets-dir=name 

                      Directory for character set files.

  -i, --comments      Write additional information.

                      (Defaults to on; use --skip-comments to disable.)

  --compatible=name   Change the dump to be compatible with a given mode. By

                      default tables are dumped in a format optimized for

                      MySQL. Legal modes are: ansi, mysql323, mysql40,

                      postgresql, oracle, mssql, db2, maxdb, no_key_options,

                      no_table_options, no_field_options. One can use several

                      modes separated by commas. Note: Requires MySQL server

                      version 4.1.0 or higher. This option is ignored with

                      earlier server versions.

  --compact           Give less verbose output (useful for debugging). Disables

                      structure comments and header/footer constructs.  Enables

                      options --skip-add-drop-table --skip-add-locks

                      --skip-comments --skip-disable-keys --skip-set-charset.

  -c, --complete-insert 

                      Use complete insert statements.

  -C, --compress      Use compression in server/client protocol.

  -a, --create-options 

                      Include all MySQL specific create options.

                      (Defaults to on; use --skip-create-options to disable.)

  -B, --databases     Dump several databases. Note the difference in usage; in

                      this case no tables are given. All name arguments are

                      regarded as database names. 'USE db_name;' will be

                      included in the output.

  -#, --debug[=#]     This is a non-debug version. Catch this and exit.

  --debug-check       Check memory and open file usage at exit.

  --debug-info        Print some debug info at exit.

  --default-character-set=name 

                      Set the default character set.

  --delayed-insert    Insert rows with INSERT DELAYED.

  --delete-master-logs 

                      Delete logs on master after backup. This automatically

                      enables --master-data.

  -K, --disable-keys  '/*!40000 ALTER TABLE tb_name DISABLE KEYS */; and

                      '/*!40000 ALTER TABLE tb_name ENABLE KEYS */; will be put

                      in the output.

                      (Defaults to on; use --skip-disable-keys to disable.)

  --dump-slave[=#]    This causes the binary log position and filename of the

                      master to be appended to the dumped data output. Setting

                      the value to 1, will printit as a CHANGE MASTER command

                      in the dumped data output; if equal to 2, that command

                      will be prefixed with a comment symbol. This option will

                      turn --lock-all-tables on, unless --single-transaction is

                      specified too (in which case a global read lock is only

                      taken a short time at the beginning of the dump - don't

                      forget to read about --single-transaction below). In all

                      cases any action on logs will happen at the exact moment

                      of the dump.Option automatically turns --lock-tables off.

  -E, --events        Dump events.

  -e, --extended-insert 

                      Use multiple-row INSERT syntax that include several

                      VALUES lists.

                      (Defaults to on; use --skip-extended-insert to disable.)

  --fields-terminated-by=name 

                      Fields in the output file are terminated by the given

                      string.

  --fields-enclosed-by=name 

                      Fields in the output file are enclosed by the given

                      character.

  --fields-optionally-enclosed-by=name 

                      Fields in the output file are optionally enclosed by the

                      given character.

  --fields-escaped-by=name 

                      Fields in the output file are escaped by the given

                      character.

  -F, --flush-logs    Flush logs file in server before starting dump. Note that

                      if you dump many databases at once (using the option

                      --databases= or --all-databases), the logs will be

                      flushed for each database dumped. The exception is when

                      using --lock-all-tables or --master-data: in this case

                      the logs will be flushed only once, corresponding to the

                      moment all tables are locked. So if you want your dump

                      and the log flush to happen at the same exact moment you

                      should use --lock-all-tables or --master-data with

                      --flush-logs.

  --flush-privileges  Emit a FLUSH PRIVILEGES statement after dumping the mysql

                      database.  This option should be used any time the dump

                      contains the mysql database and any other database that

                      depends on the data in the mysql database for proper

                      restore. 

  -f, --force         Continue even if we get an SQL error.

  -?, --help          Display this help message and exit.

  --hex-blob          Dump binary strings (BINARY, VARBINARY, BLOB) in

                      hexadecimal format.

  -h, --host=name     Connect to host.

  --ignore-table=name Do not dump the specified table. To specify more than one

                      table to ignore, use the directive multiple times, once

                      for each table.  Each table must be specified with both

                      database and table names, e.g.,

                      --ignore-table=database.table.

  --include-master-host-port 

                      Adds 'MASTER_HOST=, MASTER_PORT=' to 'CHANGE

                      MASTER TO..' in dump produced with --dump-slave.

  --insert-ignore     Insert rows with INSERT IGNORE.

  --lines-terminated-by=name 

                      Lines in the output file are terminated by the given

                      string.

  -x, --lock-all-tables 

                      Locks all tables across all databases. This is achieved

                      by taking a global read lock for the duration of the

                      whole dump. Automatically turns --single-transaction and

                      --lock-tables off.

  -l, --lock-tables   Lock all tables for read.

                      (Defaults to on; use --skip-lock-tables to disable.)

  --log-error=name    Append warnings and errors to given file.

  --master-data[=#]   This causes the binary log position and filename to be

                      appended to the output. If equal to 1, will print it as a

                      CHANGE MASTER command; if equal to 2, that command will

                      be prefixed with a comment symbol. This option will turn

                      --lock-all-tables on, unless --single-transaction is

                      specified too (in which case a global read lock is only

                      taken a short time at the beginning of the dump; don't

                      forget to read about --single-transaction below). In all

                      cases, any action on logs will happen at the exact moment

                      of the dump. Option automatically turns --lock-tables

                      off.

  --max-allowed-packet=# 

                      The maximum packet length to send to or receive from

                      server.

  --net-buffer-length=# 

                      The buffer size for TCP/IP and socket communication.

  --no-autocommit     Wrap tables with autocommit/commit statements.

  -n, --no-create-db  Suppress the CREATE DATABASE ... IF EXISTS statement that

                      normally is output for each dumped database if

                      --all-databases or --databases is given.

  -t, --no-create-info 

                      Don't write table creation info.

  -d, --no-data       No row information.

  -N, --no-set-names  Same as --skip-set-charset.

  --opt               Same as --add-drop-table, --add-locks, --create-options,

                      --quick, --extended-insert, --lock-tables, --set-charset,

                      and --disable-keys. Enabled by default, disable with

                      --skip-opt.

  --order-by-primary  Sorts each table's rows by primary key, or first unique

                      key, if such a key exists.  Useful when dumping a MyISAM

                      table to be loaded into an InnoDB table, but will make

                      the dump itself take considerably longer.

  -p, --password[=name] 

                      Password to use when connecting to server. If password is

                      not given it's solicited on the tty.

  -W, --pipe          Use named pipes to connect to server.

  -P, --port=#        Port number to use for connection.

  --protocol=name     The protocol to use for connection (tcp, socket, pipe,

                      memory).

  -q, --quick         Don't buffer query, dump directly to stdout.

                      (Defaults to on; use --skip-quick to disable.)

  -Q, --quote-names   Quote table and column names with backticks (`).

                      (Defaults to on; use --skip-quote-names to disable.)

  --replace           Use REPLACE INTO instead of INSERT INTO.

  -r, --result-file=name 

                      Direct output to a given file. This option should be used

                      in systems (e.g., DOS, Windows) that use carriage-return

                      linefeed pairs (/r/n) to separate text lines. This option

                      ensures that only a single newline is used.

  -R, --routines      Dump stored routines (functions and procedures).

  --set-charset       Add 'SET NAMES default_character_set' to the output.

                      (Defaults to on; use --skip-set-charset to disable.)

  --set-gtid-purged[=name] 

                      Add 'SET @@GLOBAL.GTID_PURGED' to the output. Possible

                      values for this option are ON, OFF and AUTO. If ON is

                      used and GTIDs are not enabled on the server, an error is

                      generated. If OFF is used, this option does nothing. If

                      AUTO is used and GTIDs are enabled on the server, 'SET

                      @@GLOBAL.GTID_PURGED' is added to the output. If GTIDs

                      are disabled, AUTO does nothing. Default is AUTO.

  --shared-memory-base-name=name 

                      Base name of shared memory.

  --single-transaction 

                      Creates a consistent snapshot by dumping all tables in a

                      single transaction. Works ONLY for tables stored in

                      storage engines which support multiversioning (currently

                      only InnoDB does); the dump is NOT guaranteed to be

                      consistent for other storage engines. While a

                      --single-transaction dump is in process, to ensure a

                      valid dump file (correct table contents and binary log

                      position), no other connection should use the following

                      statements: ALTER TABLE, DROP TABLE, RENAME TABLE,

                      TRUNCATE TABLE, as consistent snapshot is not isolated

                      from them. Option automatically turns off --lock-tables.

  --dump-date         Put a dump date to the end of the output.

                      (Defaults to on; use --skip-dump-date to disable.)

  --skip-opt          Disable --opt. Disables --add-drop-table, --add-locks,

                      --create-options, --quick, --extended-insert,

                      --lock-tables, --set-charset, and --disable-keys.

  -S, --socket=name   The socket file to use for connection.

  --ssl               Enable SSL for connection (automatically enabled with

                      other flags).

  --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 (implies --ssl).

  --ssl-cipher=name   SSL cipher to use (implies --ssl).

  --ssl-key=name      X509 key in PEM format (implies --ssl).

  --ssl-crl=name      Certificate revocation list (implies --ssl).

  --ssl-crlpath=name  Certificate revocation list path (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.

  -T, --tab=name      Create tab-separated textfile for each table to given

                      path. (Create .sql and .txt files.) NOTE: This only works

                      if mysqldump is run on the same machine as the mysqld

                      server.

  --tables            Overrides option --databases (-B).

  --triggers          Dump triggers for each dumped table.

                      (Defaults to on; use --skip-triggers to disable.)

  --tz-utc            SET TIME_ZONE='+00:00' at top of dump to allow dumping of

                      TIMESTAMP data when a server has data in different time

                      zones or data is being moved between servers with

                      different time zones.

                      (Defaults to on; use --skip-tz-utc to disable.)

  -u, --user=name     User for login if not current user.

  -v, --verbose       Print info about the various stages.

  -V, --version       Output version information and exit.

  -w, --where=name    Dump only selected records. Quotes are mandatory.

  -X, --xml           Dump a database as well formed XML.

  --plugin-dir=name   Directory for client-side plugins.

  --default-auth=name Default authentication client-side plugin to use.
