Only supertype information for UDTs matching the catalog, schema, and type name is returned. The type name parameter may be a fully-qualified name. When the UDT name supplied is a fully-qualified name, the catalog and schemaPattern parameters are ignored.
If a UDT does not have a direct super type, it is not listed here.
A row of the ResultSet

describes the designated UDT and a direct supertype. A row has the following
