Syntax:
CHECK TABLE tbl_name [, tbl_name] ... [option] ...

option = {FOR UPGRADE | QUICK | FAST | MEDIUM | EXTENDED | CHANGED}

CHECK TABLE checks a table or tables for errors. CHECK TABLE works for
InnoDB, MyISAM, ARCHIVE, and CSV tables. For MyISAM tables, the key
statistics are updated as well.

To check a table, you must have some privilege for it.

CHECK TABLE can also check views for problems, such as tables that are
referenced in the view definition that no longer exist.

CHECK TABLE is supported for partitioned tables, and you can use ALTER
TABLE ... CHECK PARTITION to check one or more partitions; for more
information, see [HELP ALTER TABLE], and
