ORA-22312

Error: ORA-22312: must specify either CASCADE or INVALIDATE option

Causa: An attempt was made to alter a type which has a dependent type or table without specifying the CASCADE or INVALIDATE option.

Acción: 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.
