DROP FUNCTION

Purpose

Use the DROP FUNCTION statement to remove a standalone stored function from the database.


Note:

Do not use this statement to remove 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.


See Also:

Prerequisites

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

Syntax

drop_function::=

Text description of drop_function


Semantics

schema

Specify the schema containing the function. If you omit schema, Oracle assumes the function is in your own schema.

function_name

Specify the name of the function to be dropped.

Oracle invalidates any local objects that depend on, or call, the dropped function. If you subsequently reference one of these objects, Oracle 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, Oracle disassociates the statistics types with the FORCE option and drops any user-defined statistics collected with the statistics type.

Example
