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!

In MySQL 3.22 or later, you can use the keywords IF EXISTS
to prevent an error from occurring for tables that don't exist.  As of
MySQL 4.1, a NOTE is generated for each non-existent table when
using IF EXISTS.
See also : [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 are using MySQL 4.1 or higher and the
TEMPORARY keyword.
