DROP FUNCTION Statement

The DROP FUNCTION statement drops a standalone 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.

Semantics

schema

Name of the schema containing the function. Default: your schema.

function_name

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.
