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 schema or you must have the DROP
ANY
PROCEDURE
system privilege.
Name of the schema containing the function. Default: your schema.
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.
