description
getSuperTypes
public ResultSet getSuperTypes(String catalog,
String schemaPattern,
String tableNamePattern)
throws SQLException
Retrieves a description of the user-defined type (UDT) hierarchies
defined in a particular schema in this database. Only the immediate
super type/sub type relationship is modeled.
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
object returned by this method
describes the designated UDT and a direct supertype. A row has the
following columns:
- TYPE_CAT String => the UDT's catalog (may be
null
)
- TYPE_SCHEM String => UDT's schema (may be
null
)
- TYPE_NAME String => type name of the UDT

(may be
null

- SUPERTYPE_SCHEM String => the direct super type's schema
(may be

Note: If the driver does not support type hierarchies, an
empty result set is returned.
