Oracle : Ошибка 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.
