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! If any of the tables named in the
argument list do not exist, MySQL returns an error indicating by name
which non-existing tables it was unable to drop, but it also drops all
of the tables in the list that do exist.

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.
