ORA-30756: cannot create column or table of type that
contains a supertype attribute

Answer Posted / guest

Cause: The user tried to create a column or table of an
object type that contains a supertype attribute. This is not
supported because it leads to infinite recursion in our
current storage model. Note that creating a column of a type
implies that we create columns corresponding to all subtype
attributes as well.

Action: Change the type definition to contain a supertype
REF attribute instead of the supertype object attribute.
