Table maintenance operations can be time\-consuming, particularly for large tables\&. If you use the +\fB\-\-databases\fR +or +\fB\-\-all\-databases\fR +option to process all tables in one or more databases, an invocation of +\fBmysqlcheck\fR +might take a long time\&. (This is also true for +\fBmysql_upgrade\fR +because that program invokes +\fBmysqlcheck\fR +to check all tables and repair them if necessary\&.) +.PP +\fBmysqlcheck\fR +is similar in function to +\fBmyisamchk\fR, but works differently\&. The main operational difference is that +\fBmysqlcheck\fR +must be used when the +\fBmysqld\fR +server is running, whereas +\fBmyisamchk\fR +should be used when it is not\&. The benefit of using +\fBmysqlcheck\fR +is that you do not have to stop the server to perform table maintenance\&. +.PP +\fBmysqlcheck\fR +uses the SQL statements +CHECK TABLE, +REPAIR TABLE, +ANALYZE TABLE, and +OPTIMIZE TABLE +in a convenient way for the user\&. It determines which statements to use for the operation you want to perform, and then sends the statements to the server to be executed\&. +.PP +The +MyISAM +storage engine supports all four maintenance operations, so +\fBmysqlcheck\fR +can be used to perform any of them on +MyISAM +tables\&. Other storage engines do not necessarily support all operations\&. In such cases, an error message is displayed\&. For example, if +test\&.t +is a +MEMORY +table, an attempt to check it produces this result: +.sp +.if n \{\ +.RS 4 +.\} +.nf +shell> \fBmysqlcheck test t\fR +test\&.t +note : The storage engine for the table doesn't support check +.fi +.if n \{\ +.RE +.\} +.PP +If +\fBmysqlcheck\fR +is unable to repair a table, see the MariaDB Knowledge Base +for manual table repair strategies\&. This will be the case, for example, for +InnoDB +tables, which can be checked with +CHECK TABLE, but not repaired with +REPAIR TABLE\&. +.PP +The use of +\fBmysqlcheck\fR +with partitioned tables is not supported\&. +.if n \{\ +.sp +.\} +.RS 4 +.it 1 an-trap +.nr an-no-space-flag 1 +.nr an-break-flag 1 +.br +.ps +1 +\fBCaution\fR +.ps -1 +.br +.PP +It is best to make a backup of a table before performing a table repair operation; under some circumstances the operation might cause data loss\&.

The default behavior of checking tables (\fB\-\-check\fR) can be changed by renaming the binary\&. If you want to have a tool that repairs tables by default, you should just make a copy of +\fBmysqlcheck\fR +named +\fBmysqlrepair\fR, or make a symbolic link to +\fBmysqlcheck\fR +named +\fBmysqlrepair\fR\&.
