ORA-02303: cannot drop or replace a type with type or table
dependents

Cause: An attempt was made to drop or replace a type that

supertype of the type being dropped.

Action: Drop all type(s) and table(s) depending on the type,
then retry the operation using the VALIDATE option, or use
the FORCE option.
