Dumping structure and contents of MySQLdatabases 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 thefollowing files in the given order:
/etc/my.cnf /etc/mysql/my.cnf/usr/local/mysql/etc/my.cnf ~/.my.cnf
The following groups are read:mysqldump client
The following options may be given asthe first argument:
--print-defaults Print the program argument list andexit.
--no-defaults Don‘t read default options from anyoption file,
except for login file.
--defaults-file=# Only read default options from the givenfile #.
--defaults-extra-file=# Read this fileafter the global files are read.
--defaults-group-suffix=#
Also read groups withconcat(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 databasesselected.
-Y, --all-tablespaces
Dump all the tablespaces.
-y, --no-tablespaces
Do not dump anytablespace information.
--add-drop-database Add a DROP DATABASE beforeeach create.
--add-drop-table Add a DROPTABLE before each create.
(Defaults to on; use--skip-add-drop-table to disable.)
--add-drop-trigger Add a DROPTRIGGER before each create.
--add-locks Add locksaround INSERT statements.
(Defaults to on; use--skip-add-locks to disable.)
--allow-keywords Allow creationof column names that are keywords.
--apply-slave-statements
Adds ‘STOP SLAVE‘ priorto ‘CHANGE MASTER‘ and ‘START
SLAVE‘ to bottom of dump.
--bind-address=name IP address to bind to.
--character-sets-dir=name
Directory for characterset files.
-i, --comments Writeadditional information.
(Defaults to on; use--skip-comments to disable.)
--compatible=name Change thedump to be compatible with a given mode. By
default tables are dumpedin a format optimized for
MySQL. Legalmodes are: ansi, mysql323, mysql40,
postgresql, oracle,mssql, db2, maxdb, no_key_options,
no_table_options,no_field_options. One can use several
modes separated bycommas. Note: Requires MySQL server
version 4.1.0 or higher.This option is ignored with
earlier server versions.
--compact Give lessverbose output (useful for debugging). Disables
structure comments and header/footerconstructs. 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 Usecompression in server/client protocol.
-a, --create-options
Include all MySQLspecific create options.
(Defaults to on; use--skip-create-options to disable.)
-B, --databases Dump severaldatabases. Note the difference in usage; in
this case no tables aregiven. All name arguments are
regarded as databasenames. ‘USE db_name;‘ will be
included in the output.
-#, --debug[=#] This is anon-debug version. Catch this and exit.
--debug-check Check memoryand open file usage at exit.
--debug-info Print somedebug info at exit.
--default-character-set=name
Set thedefault character set.
--delayed-insert Insert rowswith INSERT DELAYED.
--delete-master-logs
Delete logs on masterafter backup. This automatically
enables --master-data.
-K, --disable-keys ‘/*!40000ALTER TABLE tb_name DISABLE KEYS */; and
‘/*!40000 ALTER TABLEtb_name ENABLE KEYS */; will be put
in the output.
(Defaults to on; use--skip-disable-keys to disable.)
--dump-slave[=#] This causesthe binary log position and filename of the
master to be appended tothe dumped data output. Setting
the value to 1, willprintit as a CHANGE MASTER command
in the dumped data output; if equal to2, that command
will be prefixed with acomment symbol. This option will
turn --lock-all-tableson, unless --single-transaction is
specified too (in whichcase a global read lock is only
taken a short time at thebeginning of the dump - don‘t
forget to read about--single-transaction below). In all
cases any action on logswill happen at the exact moment
of the dump.Optionautomatically turns --lock-tables off.
-E, --events Dump events.
-e, --extended-insert
Use multiple-row INSERTsyntax that include several
VALUES lists.
(Defaults to on; use--skip-extended-insert to disable.)
--fields-terminated-by=name
Fields in the output fileare terminated by the given
string.
--fields-enclosed-by=name
Fields in the output fileare enclosed by the given
character.
--fields-optionally-enclosed-by=name
Fields in the output fileare optionally enclosed by the
given character.
--fields-escaped-by=name
Fields in the output fileare escaped by the given
character.
-F, --flush-logs Flush logsfile in server before starting dump. Note that
if you dump manydatabases at once (using the option
--databases= or--all-databases), the logs will be
flushed for each databasedumped. The exception is when
using --lock-all-tablesor --master-data: in this case
the logs will be flushedonly once, corresponding to the
moment all tables arelocked. So if you want your dump
and the log flush tohappen at the same exact moment you
should use--lock-all-tables or --master-data with
--flush-logs.
--flush-privileges Emit a FLUSHPRIVILEGES statement after dumping the mysql
database. This option should be used any time the dump
contains the mysqldatabase and any other database that
depends on the data inthe mysql database for proper
restore.
-f, --force Continue evenif we get an SQL error.
-?, --help Display this help message and exit.
--hex-blob Dump binarystrings (BINARY, VARBINARY, BLOB) in
hexadecimal format.
-h, --host=name Connect tohost.
--ignore-table=name Do not dump the specified table. To specify morethan one
table to ignore, use thedirective 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=<host>, MASTER_PORT=<port>‘ to ‘CHANGE
MASTER TO..‘ in dumpproduced with --dump-slave.
--insert-ignore Insert rows withINSERT IGNORE.
--lines-terminated-by=name
Lines in the output fileare terminated by the given
string.
-x, --lock-all-tables
Locks all tables acrossall databases. This is achieved
by taking a global readlock for the duration of the
whole dump. Automaticallyturns --single-transaction and
--lock-tables off.
-l, --lock-tables Lock alltables for read.
(Defaults to on; use--skip-lock-tables to disable.)
--log-error=name Appendwarnings and errors to given file.
--master-data[=#] This causesthe binary log position and filename to be
appended to the output.If equal to 1, will print it as a
CHANGE MASTER command; ifequal to 2, that command will
be prefixed with acomment symbol. This option will turn
--lock-all-tables on,unless --single-transaction is
specified too (in whichcase a global read lock is only
taken a short time at thebeginning of the dump; don‘t
forget to read about--single-transaction below). In all
cases, any action on logs will happen at theexact moment
of the dump. Optionautomatically turns --lock-tables
off.
--max-allowed-packet=#
The maximum packet lengthto send to or receive from
server.
--net-buffer-length=#
The buffer size forTCP/IP and socket communication.
--no-autocommit Wrap tableswith autocommit/commit statements.
-n, --no-create-db Suppress theCREATE DATABASE ... IF EXISTS statement that
normally is output foreach dumped database if
--all-databases or--databases is given.
-t, --no-create-info
Don‘t write tablecreation info.
-d, --no-data No rowinformation.
-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 eachtable‘s rows by primary key, or first unique
key, if such a keyexists. Useful when dumping a MyISAM
table to be loadedinto an InnoDB table, but will make
the dump itself takeconsiderably longer.
-p, --password[=name]
Password to use whenconnecting to server. If password is
not given it‘s solicited on the tty.
-P, --port=# Port number touse for connection.
--protocol=name The protocolto use for connection (tcp, socket, pipe,
memory).
-q, --quick Don‘t bufferquery, dump directly to stdout.
(Defaults to on; use--skip-quick to disable.)
-Q, --quote-names Quote tableand column names with backticks (`).
(Defaults to on; use--skip-quote-names to disable.)
--replace Use REPLACEINTO instead of INSERT INTO.
-r, --result-file=name
Direct output to a givenfile. This option should be used
in systems (e.g., DOS,Windows) that use carriage-return
linefeed pairs (\r\n) toseparate text lines. This option
ensures that only asingle newline is used.
-R, --routines Dump storedroutines (functions and procedures).
--set-charset Add ‘SET NAMESdefault_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 optionare ON, OFF and AUTO. If ON is
used and GTIDs are notenabled on the server, an error is
generated. If OFF isused, this option does nothing. If
AUTO is used and GTIDsare enabled on the server, ‘SET
@@GLOBAL.GTID_PURGED‘ is added to theoutput. If GTIDs
are disabled, AUTO doesnothing. If no value is supplied
then the default (AUTO)value will be considered.
--single-transaction
Creates a consistent snapshot by dumping alltables in a
single transaction. WorksONLY for tables stored in
storage engines whichsupport multiversioning (currently
only InnoDB does); the dumpis NOT guaranteed to be
consistent for otherstorage engines. While a
--single-transaction dumpis in process, to ensure a
valid dump file (correcttable contents and binary log
position), no otherconnection should use the following
statements: ALTER TABLE,DROP TABLE, RENAME TABLE,
TRUNCATE TABLE, asconsistent snapshot is not isolated
from them. Optionautomatically turns off --lock-tables.
--dump-date Put a dumpdate 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 socketfile to use for connection.
--secure-auth Refuse clientconnecting to server if it uses old
(pre-4.1.1) protocol.
(Defaults to on; use--skip-secure-auth to disable.)
--ssl Enable SSL forconnection (automatically enabled with
other flags).
--ssl-ca=name CA file in PEMformat (check OpenSSL docs, implies
--ssl).
--ssl-capath=name CA directory(check OpenSSL docs, implies --ssl).
--ssl-cert=name X509 cert inPEM format (implies --ssl).
--ssl-cipher=name SSL cipher touse (implies --ssl).
--ssl-key=name X509 key inPEM format (implies --ssl).
--ssl-crl=name Certificaterevocation list (implies --ssl).
--ssl-crlpath=name Certificaterevocation list path (implies --ssl).
--ssl-verify-server-cert
Verify server‘s"Common Name" in its cert against
hostname used whenconnecting. This option is disabled by
default.
-T, --tab=name Createtab-separated textfile for each table to given
path. (Create .sql and.txt files.) NOTE: This only works
if mysqldump is run onthe same machine as the mysqld
server.
--tables Overridesoption --databases (-B).
--triggers Dump triggersfor each dumped table.
(Defaults to on; use--skip-triggers to disable.)
--tz-utc SETTIME_ZONE=‘+00:00‘ at top of dump to allow dumping of
TIMESTAMP data when aserver has data in different time
zones or data is beingmoved between servers with
different time zones.
(Defaults to on; use--skip-tz-utc to disable.)
-u, --user=name User for loginif not current user.
-v, --verbose Print infoabout the various stages.
-V, --version Output versioninformation and exit.
-w, --where=name Dump onlyselected records. Quotes are mandatory.
-X, --xml Dump adatabase as well formed XML.
