DESCRIPTION

Dumping definition and data mysql database or table mysqldump supports by executing
-A|--all-databases
  Dump all the databases. This will be same as --databases with all databases selected.
-a|--all
  Include all MySQL specific create options.
-#|--debug=...
  Output debug log. Often this is ’d:t:o,filename‘.
--character-sets-dir=...
  Directory where character sets are
-?|--help
  Display this help message and exit.
-B|--databases
  To dump several databases. Note the difference in usage; In this case no tables are given. All name arguments are regarded as databasenames.
-c|--complete-insert
  Use complete insert statements.
-C|--compress
  Use compression in server/client protocol.
--default-character-set=...
  Set the default character set
-e|--extended-insert
  Allows utilization of the new, much faster INSERT syntax.
--add-drop-table
  Add a ’drop table’ before each create.
--add-locks
  Add locks around insert statements.
--allow-keywords
  Allow creation of column names that are keywords.
--delayed-insert
  Insert rows with INSERT DELAYED.
-F|--flush-logs
  Flush logs file in server before starting dump.
-f|--force
  Continue even if we get an sql-error.
-h|--host=...
  Connect to host.
-l|--lock-tables
  Lock all tables for read.
-n|--no-create-db
  ’CREATE DATABASE /*!32312 IF NOT EXISTS*/ db_name;’ will not be put in the output. The above line will be added otherwise, if --databases or --all-databases option was given.
-t|--no-create-info
  Don’t write table creation info.
-d|--no-data
  No row information.
-O|--set-variable var=option
  give a variable a value. --help lists variables
--opt Same as --add-drop-table --add-locks --all --extended-insert --quick --lock-tables
-p|--password[=...]
  Password to use when connecting to server. If password is not given it’s solicited on the tty.
-P|--port=...
  Port number to use for connection.
-q|--quick
  Don’t buffer query, dump directly to stdout.
-Q|--quote-names
  Quote table and column names with ‘
-S|--socket=...
  Socket file to use for connection.
--tables
  Overrides option --databases(-B).
-T|--tab=...
  Creates tab separated textfile for each table to given path. (creates .sql and .txt files). NOTE: This only works if mysqldump is run on the same machine as the mysqld daemon.
-u|--user=#
  User for login if not current user.
-v|--verbose
  Print info about the various stages.
-V|--version
  Output version information and exit.
-w|--where=
  dump only selected records; QUOTES mandatory!
--delayed
  Insert rows with the INSERT DELAYED command.
-e|--extended-insert
  Use the new multiline INSERT syntax. (Gives more compact and faster inserts statements.)
--fields-terminated-by=...
--fields-enclosed-by=...
--fields-optionally-enclosed-by=...
--fields-escaped-by=...
--lines-terminated-by=...
  These options are used with the -T option and have the same meaning as the corresponding clauses for LOAD DATA INFILE. See Mysql manual section 7.23 LOAD DATA INFILE Syntax.
-v|--verbose
  Verbose mode. Print out more information on what the program does.
-V|--version
  Print version information and exit.
-O net_buffer_length=#, where # < 16M
  When creating multi-row-insert statements (as with option --extended-insert or --opt ), mysqldump will create rows up to net_buffer_length length. If you increase this variable, you should also ensure that the max_allowed_packet variable in the MySQL server is bigger than the net_buffer_length.

EXAMPLES

The most normal use of mysqldump is probably for making a backup of whole databases. See Mysql Manual section 21.2 Database Backups.
mysqldump --opt database > backup-file.sql
You can read this back into MySQL with:
mysql
  database < backup-file.sql
or
mysql
-e ’source /patch-to-backup/backup-file.sql’ database
However, it’s also very useful to populate another MySQL server with information from a database:
mysqldump --opt database | mysql --host=remote-host -C database
It is possible to dump several databases with one command:
mysqldump --databases database1 [ database2 database3... ] > my_databases.sql
If all the databases are wanted, one can use:
mysqldump --all-databases > all_databases.sql
