DROP FUNCTION Statement

The DROP FUNCTION statement drops a standalone stored function from the database.

Note:

Do not use this statement to drop a function that is part of a package. Instead, either drop the entire package using the "DROP PACKAGE Statement" or redefine the package without the function using the "CREATE PACKAGE Statement" with the OR REPLACE clause.

Topics:

Prerequisites

The function must be in your own schema or you must have the DROP ANY PROCEDURE system privilege.

Syntax

drop_function ::=

drop_function
Description of the illustration drop_function.gif

Semantics

schema

The name of the schema containing the function. The default is your own schema.

function_name

The name of the function to be dropped.

The database invalidates any local objects that depend on, or invoke, the dropped function. If you subsequently reference one of these objects, then the database tries to recompile the object and returns an error if you have not re-created the dropped function.

If any statistics types are associated with the function, then the database disassociates the statistics types with the FORCE option and drops any user-defined statistics collected with the statistics type.
