.SH "SYNOPSIS"
|
|
.HP \w'\fBmysqlcheck\ [\fR\fB\fIoptions\fR\fR\fB]\ [\fR\fB\fIdb_name\fR\fR\fB\ [\fR\fB\fItbl_name\fR\fR\fB\ \&.\&.\&.]]\fR\ 'u

\fBmysqlcheck [\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
|
|
\fBmysqlcheck\fR
|
|
client performs table maintenance: It checks, repairs, optimizes, or analyzes tables\&.
|
|
.PP
|
|
Each table is locked and therefore unavailable to other sessions while it is being processed, although for check operations, the table is locked with a
|
|
READ
|
|
lock only\&. 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\&.

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\&. Possible causes include but are not limited to file system errors\&.

There are three general ways to invoke
|

\fBmysqlcheck\fR:
|
|
.sp
|
|
.if n \{\

|

If you do not name any tables following
|

\fIdb_name\fR

or if you use the

\fB\-\-databases\fR

\fB\-\-all\-databases\fR
|

option, entire databases are checked\&.
|
|
.PP
|
|
\fBmysqlcheck\fR
|
|
has a special feature compared to other client programs\&. 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\&. If you invoke
|
|
\fBmysqlrepair\fR, it repairs tables\&.
