Syntax:
DROP [TEMPORARY] TABLE [IF EXISTS]
    tbl_name [, tbl_name] ...
    [RESTRICT | CASCADE]

DROP TABLE removes one or more tables. You must have the DROP privilege
for each table. All table data and the table definition are removed, so
be careful with this statement!

Use IF EXISTS to prevent an error from occurring for tables that do not
exist. A NOTE is generated for each non-existent table when using IF
EXISTS. See [show-warnings].

RESTRICT and CASCADE are allowed to make porting easier. For the
moment, they do nothing.

Note: DROP TABLE automatically commits the current active transaction,
unless you use the TEMPORARY keyword.
