The DROP
FUNCTION
statement drops a standalone stored 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 theOR
REPLACE
clause.The function must be in your own schema or you must have the DROP
ANY
PROCEDURE
system privilege.
Keyword and Parameter Descriptions
Specify the schema containing the function. If you omit schema
, then the database assumes the function is in your own schema.
Specify the name of the function to be dropped.
The 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.
