.SH "NAME"
mysqldump \- a database backup program
.SH "SYNOPSIS"
.HP \w'\fBmysqldump\ [\fR\fB\fIoptions\fR\fR\fB]\ [\fR\fB\fIdb_name\fR\fR\fB\ [\fR\fB\fItbl_name\fR\fR\fB\ \&.\&.\&.]]\fR\ 'u
\fBmysqldump [\fR\fB\fIoptions\fR\fR\fB] [\fR\fB\fIdb_name\fR\fR\fB [\fR\fB\fItbl_name\fR\fR\fB \&.\&.\&.]]\fR
.SH "DESCRIPTION"
.PP
The
\fBmysqldump\fR
client is a backup program originally written by Igor Romanenko\&. It can be used to dump a database or a collection of databases for backup or transfer to another SQL server (not necessarily a MariaDB server)\&. The dump typically contains SQL statements to create the table, populate it, or both\&. However,
\fBmysqldump\fR
can also be used to generate files in CSV, other delimited text, or XML format\&.
.PP
If you are doing a backup on the server and your tables all are
MyISAM
tables, consider using the
\fBmysqlhotcopy\fR
instead because it can accomplish faster backups and faster restores\&. See
\fBmysqlhotcopy\fR(1)\&.
.PP
There are four general ways to invoke
\fBmysqldump\fR:
.sp
.if n \{\
.RS 4
.\}
.nf
shell> \fBmysqldump [\fR\fB\fIoptions\fR\fR\fB] \fR\fB\fIdb_name\fR\fR\fB [\fR\fB\fItbl_name\fR\fR\fB \&.\&.\&.]\fR
shell> \fBmysqldump [\fR\fB\fIoptions\fR\fR\fB] \-\-databases \fR\fB\fIdb_name\fR\fR\fB \&.\&.\&.\fR
shell> \fBmysqldump [\fR\fB\fIoptions\fR\fR\fB] \-\-all\-databases\fR
shell> \fBmysqldump [\fR\fB\fIoptions\fR\fR\fB] \-\-system={options}\fR
.fi
.if n \{\
.RE
.\}
.PP
If you do not name any tables following
\fIdb_name\fR
or if you use the
\fB\-\-databases\fR
or
\fB\-\-all\-databases\fR
option, entire databases are dumped\&.
.PP
\fBmysqldump\fR
does not dump the
INFORMATION_SCHEMA or performance_schema
databases by default\&. To dump these,
name them explicitly on the command line, although you must also use the
\fB\-\-skip\-lock\-tables\fR
option\&.
.PP
To see a list of the options your version of
\fBmysqldump\fR
supports, execute
\fBmysqldump \-\-help\fR\&.
.PP
Some
\fBmysqldump\fR
options are shorthand for groups of other options:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
Use of
\fB\-\-opt\fR
is the same as specifying
\fB\-\-add\-drop\-table\fR,
\fB\-\-add\-locks\fR,
\fB\-\-create\-options\fR,
\fB\-\-disable\-keys\fR,
\fB\-\-extended\-insert\fR,
\fB\-\-lock\-tables\fR,
\fB\-\-quick\fR, and
\fB\-\-set\-charset\fR\&. All of the options that
\fB\-\-opt\fR
stands for also are on by default because
\fB\-\-opt\fR
is on by default\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
Use of
\fB\-\-compact\fR
is the same as specifying
\fB\-\-skip\-add\-drop\-table\fR,
\fB\-\-skip\-add\-locks\fR,
\fB\-\-skip\-comments\fR,
\fB\-\-skip\-disable\-keys\fR, and
\fB\-\-skip\-set\-charset\fR
options\&.
.RE
.PP
To reverse the effect of a group option, uses its
\fB\-\-skip\-\fR\fB\fIxxx\fR\fR
form (\fB\-\-skip\-opt\fR
or
\fB\-\-skip\-compact\fR)\&. It is also possible to select only part of the effect of a group option by following it with options that enable or disable specific features\&. Here are some examples:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
To select the effect of
\fB\-\-opt\fR
except for some features, use the
\fB\-\-skip\fR
option for each feature\&. To disable extended inserts and memory buffering, use
\fB\-\-opt\fR
\fB\-\-skip\-extended\-insert\fR
\fB\-\-skip\-quick\fR\&. (Actually,
\fB\-\-skip\-extended\-insert\fR
\fB\-\-skip\-quick\fR
is sufficient because
\fB\-\-opt\fR
is on by default\&.)
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
To reverse
\fB\-\-opt\fR
for all features except index disabling and table locking, use
\fB\-\-skip\-opt\fR
\fB\-\-disable\-keys\fR
\fB\-\-lock\-tables\fR\&.
.RE
.PP
When you selectively enable or disable the effect of a group option, order is important because options are processed first to last\&. For example,
\fB\-\-disable\-keys\fR
\fB\-\-lock\-tables\fR
\fB\-\-skip\-opt\fR
would not have the intended effect; it is the same as
\fB\-\-skip\-opt\fR
by itself\&.
.PP
\fBmysqldump\fR
can retrieve and dump table contents row by row, or it can retrieve the entire content from a table and buffer it in memory before dumping it\&. Buffering in memory can be a problem if you are dumping large tables\&. To dump tables row by row, use the
\fB\-\-quick\fR
option (or
\fB\-\-opt\fR, which enables
\fB\-\-quick\fR)\&. The
\fB\-\-opt\fR
option (and hence
\fB\-\-quick\fR) is enabled by default, so to enable memory buffering, use
\fB\-\-skip\-quick\fR\&.
.PP
If you are using a recent version of
\fBmysqldump\fR
to generate a dump to be reloaded into a very old MySQL server, you should not use the
\fB\-\-opt\fR
or
\fB\-\-extended\-insert\fR
option\&. Use
\fB\-\-skip\-opt\fR
instead\&.
.RE
.PP
\fBmysqldump\fR
supports the following options, which can be specified on the command line or in the
[mysqldump]
