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

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

CHECK TABLE works for InnoDB, MyISAM, ARCHIVE, and CSV tables.

Before running CHECK TABLE on InnoDB tables, see
https://dev.mysql.com/doc/refman/8.0/en/check-table.html#check-table-in
nodb.

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
https://dev.mysql.com/doc/refman/8.0/en/partitioning-maintenance.html.

CHECK TABLE ignores virtual generated columns that are not indexed.
