DROP FUNCTION

The DROP FUNCTION statement removes a standalone stored function from the database. Do not use this statement to remove a function that is part of a package.

Required privilege

No privilege is required for the function owner.

DROP ANY PROCEDURE for another user's function.

SQL syntax

DROP FUNCTION [Owner.]FunctionName

Parameters

The DROP FUNCTION statement has the parameter:

Parameter	Description
`[Owner.]FunctionName`	Name of the function to be dropped.

Description

When you drop a function, TimesTen invalidates objects that depend on the dropped function. If you subsequently reference one of these objects, TimesTen attempts to recompile the object and returns an error message if you have not re-created the dropped function.
Do not use this statement to remove a function that is part of a package. Either drop the package or redefine the package without the function using the CREATE PACKAGE statement with the OR REPLACE clause
To use the DROP FUNCTION statement, you must have PL/SQL enabled in your database. If you do not have PL/SQL enabled in your database, an error is thrown.

Examples

The following statement drops the function myfunc and invalidates all objects that depend on myfunc:

Command> DROP FUNCTION myfunc;
 
Function dropped.

If PL/SQL is not enabled in your database, TimesTen returns an error:

Command> DROP FUNCTION myfunc; 8501: PL/SQL feature not installed in this TimesTen databaseThe command failed.
