SHOW TABLE STATUS
Synopsis
SHOW TABLE STATUS [FROMdatabase] [LIKE 'pattern']
This statement displays status information on a set of tables from a database.
To obtain the status of tables from a database other than the current
default one, use the FROM clause. The results include information on all of the tables of
the database, unless the LIKE clause is used to limit the
tables displayed by a naming pattern:
SHOW TABLE STATUS FROM human_resources
LIKE 'employees' \G

these variables or table options using the ALTER TABLE statement; see the ALTER TABLE: Table options” subsection earlier in this
chapter.
