Functions are defined using PL/SQL. Please refer to Oracle Database PL/SQL Language Reference for complete information on creating, altering, and dropping functions.

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


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.


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

Description of the illustration drop_function.gif



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


Specify the name of the function to be dropped.

Oracle Database invalidates any local objects that depend on, or call, 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.
