DROP FUNCTION

Syntax

Purpose

To remove a standalone stored function from the database. For information on creating a function, see "CREATE FUNCTION".

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.

Prerequisites

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

Keywords and Parameters

schema	is the schema containing the function. If you omit schema, Oracle assumes the function is in your own schema.
function_name	is 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. See Also: Oracle8i Concepts for more information on how Oracle maintains dependencies among schema objects, including remote objects.
	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. See Also: "ASSOCIATE STATISTICS" and "DISASSOCIATE STATISTICS" for more information on statistics type associations.

Example

The following statement drops the function NEW_ACCT in the schema RIDDLEY and invalidates all objects that depend upon NEW_ACCT:

DROP FUNCTION riddley.new_acct;
