Oracle Error Message
ORA-22312: must specify either CASCADE or INVALIDATE option
Reason for the Error
An attempt was made to alter a type which has a dependent type or table without specifying the CASCADE or INVALIDATE option.
Solution
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.
