Syntax

REPAIR [NO_WRITE_TO_BINLOG | LOCAL] TABLE
    tbl_name [, tbl_name] ...
    [QUICK] [EXTENDED] [USE_FRM]

Description

REPAIR TABLE repairs a possibly corrupted table. By default, it has the same effect as

myisamchk --recover tbl_name

or

aria_chk --recover tbl_name

See aria_chk and myisamchk for more.

REPAIR TABLE works for Archive, Aria, CSV and MyISAM tables. For XtraDB/InnoDB, see recovery modes. For CSV, see also Checking and Repairing CSV Tables. For Archive, this statement also improves compression. If the storage engine does not support this statement, a warning is issued.

This statement requires SELECT and INSERT privileges for the table.

By default, REPAIR TABLE statements are written to the binary log and will be replicated. The NO_WRITE_TO_BINLOG keyword (LOCAL is an alias) will ensure the statement is not written to the binary log.

When an index is recreated, the storage engine may use a configurable buffer in the process. Incrementing the buffer speeds up the index creation. Aria and MyISAM allocate a buffer whose size is defined by aria_sort_buffer_size or myisam_sort_buffer_size, also used for ALTER TABLE.

REPAIR TABLE is also supported for partitioned tables. However, the USE_FRM option cannot be used with this statement on a partitioned table.

ALTER TABLE ... REPAIR PARTITION can be used to repair one or more partitions.

Since MariaDB 5.3, the Aria storage engine supports progress reporting for this statement.
