DROP PROCEDURE procedureName
Identifies the particular procedure to be dropped, and is valid only if there is exactly one procedure instance with the procedureName in the schema. The identified procedure can have any number of parameters defined for it. If no procedure with the indicated name in the named or implied schema, an error (SQLSTATE 42704) will occur. An error will also occur if there is more than one specific instance of the procedure in the named or implied schema.
