DROP {PROCEDURE | FUNCTION} [IF EXISTS] sp_name
This statement is used to drop a stored procedure or function.
That is, the specified routine is removed from the server. As of
MySQL 5.0.3, you must have the ALTER
ROUTINE privilege for the routine. (That privilege is
granted automatically to the routine creator.)
The IF EXISTS clause is a MySQL extension. It
prevents an error from occurring if the procedure or function does
not exist. A warning is produced that can be viewed with
SHOW WARNINGS.
DROP FUNCTION is also used to drop user-defined
functions (see Section 12.5.3.2, “DROP FUNCTION Syntax”).
