ORA-22312: must specify either CASCADE or INVALIDATE option
Cause: An attempt was made to alter a type which has a dependent type or table without specifying the CASCADE or INVALIDATE option.
Action: Resubmit the statement with either the CASCADE or INVALIDATE option. Specify CASCADE if you want to cascade the type change to dependent types and tables; otherwise, specify INVALIDATE to invalidate all dependents.
