                                 throws java.sql.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: 1. TYPE_CAT String => the UDT's catalog (may be null) 2. TYPE_SCHEM String => UDT's schema (may be null) 3. TYPE_NAME String => type name of the UDT 4. SUPERTYPE_CAT String => the direct super type's catalog (may be null) 5. SUPERTYPE_SCHEM String => the direct super type's schema (may be null) 6. SUPERTYPE_NAME String => the direct super type's name Note: If the driver does not support type hierarchies, an empty result set is returned.

Specified by:

Parameters:

                                  throws java.sql.SQLException

Retrieves a description of the table hierarchies defined in a particular schema in this database. Only supertable information for tables matching the catalog, schema and table name are returned. The table name parameter may be a fully- qualified name, in which case, the catalog and schemaPattern parameters are ignored. If a table does not have a super table, it is not listed here. Supertables have to be defined in the same catalog and schema as the sub tables. Therefore, the type description does not need to include this information for the supertable. Each type description has the following columns: 1. TABLE_CAT String => the type's catalog (may be null) 2. TABLE_SCHEM String => type's schema (may be null) 3. TABLE_NAME String => type name 4. SUPERTABLE_NAME String => the direct super type's name Note: If the driver does not support type hierarchies, an empty result set is returned.

Specified by:

getSuperTables in interface java.sql.DatabaseMetaData

Parameters:

catalog - - a catalog name; "" retrieves those without a catalog; null means drop catalog name from the selection criteria

schemaPattern - - a schema name pattern; "" retrieves those without a schema

tableNamePattern - - a table name pattern; may be a fully-qualified name
