The
\fBmysqlpump\fR
client utility performs
logical backups, producing a set of SQL statements that can be executed to reproduce the original database object definitions and table data\&. It dumps one or more MySQL databases for backup or transfer to another SQL server\&.

is deprecated as of MySQL 8\&.0\&.34; expect it to be removed in a future version of MySQL\&. You can use such MySQL programs as

Consider using the

Dumps can be easily imported into a MySQL Server instance or a MySQL HeatWave Service DB System using the
\m[blue]\fBMySQL Shell load dump utilities\fR\m[]\&\s-2\u[2]\d\s+2\&. Installation instructions for MySQL Shell can be found
\m[blue]\fBhere\fR\m[]\&\s-2\u[3]\d\s+2\&.

uses MySQL features introduced in MySQL 5\&.7, and thus assumes use with MySQL 5\&.7 or higher\&.

\fBmysqlpump\fR
requires at least the
SELECT
privilege for dumped tables,
SHOW VIEW
for dumped views,
TRIGGER
for dumped triggers, and
LOCK TABLES
if the
\fB\-\-single\-transaction\fR
option is not used\&. The
SELECT
privilege on the
mysql
system database is required to dump user definitions\&. Certain options might require other privileges as noted in the option descriptions\&.

To reload a dump file, you must have the privileges required to execute the statements that it contains, such as the appropriate
CREATE
privileges for objects created by those statements\&.

A dump made using PowerShell on Windows with output redirection creates a file that has UTF\-16 encoding:
.sp
.if n \{\
.RS 4
.\}
.nf
mysqlpump [options] > dump\&.sql
.fi
.if n \{\
.RE
.\}
.PP
However, UTF\-16 is not permitted as a connection character set (see
Section\ \&12.4, \(lqConnection Character Sets and Collations\(rq), so the dump file cannot be loaded correctly\&. To work around this issue, use the
\fB\-\-result\-file\fR
option, which creates the output in ASCII format:
.sp
.if n \{\
.RS 4
.\}
.nf
mysqlpump [options] \-\-result\-file=dump\&.sql

.if n \{\

By default,
\fBmysqlpump\fR
dumps all databases (with certain exceptions noted in
mysqlpump Restrictions)\&. To specify this behavior explicitly, use the
\fB\-\-all\-databases\fR
option:
.sp
.if n \{\
.RS 4
.\}
.nf
mysqlpump \-\-all\-databases
.fi
.if n \{\
.RE
.\}
.PP
To dump a single database, or certain tables within that database, name the database on the command line, optionally followed by table names:
.sp
.if n \{\
.RS 4
.\}
.nf
mysqlpump \fIdb_name\fR
mysqlpump \fIdb_name tbl_name1 tbl_name2 \&.\&.\&.\fR
.fi
.if n \{\
.RE
.\}
.PP
To treat all name arguments as database names, use the
\fB\-\-databases\fR
option:
.sp
.if n \{\
.RS 4
.\}
.nf
mysqlpump \-\-databases \fIdb_name1 db_name2\fR \&.\&.\&.
.fi
.if n \{\
.RE
.\}
.PP
By default,
\fBmysqlpump\fR
does not dump user account definitions, even if you dump the
mysql
system database that contains the grant tables\&. To dump grant table contents as logical definitions in the form of
CREATE USER
and
GRANT
statements, use the
\fB\-\-users\fR
option and suppress all database dumping:
.sp
.if n \{\
.RS 4
.\}
.nf
mysqlpump \-\-exclude\-databases=% \-\-users
.fi
.if n \{\
.RE
.\}
.PP
In the preceding command,
%
is a wildcard that matches all database names for the
\fB\-\-exclude\-databases\fR
option\&.
.PP
\fBmysqlpump\fR
supports several options for including or excluding databases, tables, stored programs, and user definitions\&. See
mysqlpump Object Selection\&.
.PP
To reload a dump file, execute the statements that it contains\&. For example, use the
\fBmysql\fR
client:
.sp
.if n \{\
.RS 4
.\}
.nf
mysqlpump [options] > dump\&.sql
mysql < dump\&.sql
.fi
.if n \{\

\fBmysqlpump\fR
usage examples\&.

\fBmysqlpump\fR

mysqlpump Option Summary
.PP
\fBmysqlpump\fR
supports the following options, which can be specified on the command line or in the

read the
