                        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
SUPERTYPE_CAT String => the direct super type's catalog (may be null)
SUPERTYPE_SCHEM String => the direct super type's schema (may be null)
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:: getSuperTypes in interface 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; typeNamePattern - a UDT name pattern; may be a fully-qualified name

                         throws 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:

TABLE_CAT String => the type's catalog (may be null)
TABLE_SCHEM String => type's schema (may be null)
TABLE_NAME String => type name
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 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

Retrieves a description of the given attribute of the given type for a user-defined type (UDT) that is available in the given schema and catalog.

Descriptions are returned only for attributes of UDTs matching the catalog, schema, type, and attribute name criteria. They are ordered by TYPE_SCHEM, TYPE_NAME and ORDINAL_POSITION. This description does not contain inherited attributes.

The ResultSet object that is returned has the following columns:

TYPE_CAT String => type catalog (may be null)
TYPE_SCHEM String => type schema (may be null)
TYPE_NAME String => type name
ATTR_NAME String => attribute name
DATA_TYPE int => attribute type SQL type from java.sql.Types
ATTR_TYPE_NAME String => Data source dependent type name. For a UDT, the type name is fully qualified. For a REF, the type name is fully qualified and represents the target type of the reference type.
ATTR_SIZE int => column size. For char or date types this is the maximum number of characters; for numeric or decimal types this is precision.
DECIMAL_DIGITS int => the number of fractional digits
NUM_PREC_RADIX int => Radix (typically either 10 or 2)
NULLABLE int => whether NULL is allowed
- attributeNoNulls - might not allow NULL values
- attributeNullable - definitely allows NULL values
- attributeNullableUnknown - nullability unknown
REMARKS String => comment describing column (may be null)
ATTR_DEF String => default value (may be null)

IS_NULLABLE String => "NO" means column definitely does not allow NULL values; "YES" means the column might allow NULL values. An empty string means unknown.
SCOPE_CATALOG String => catalog of table that is the scope of a reference attribute (null if DATA_TYPE isn't REF)
SCOPE_SCHEMA String => schema of table that is the scope of a reference attribute (null if DATA_TYPE isn't REF)
SCOPE_TABLE String => table name that is the scope of a reference attribute (null if the DATA_TYPE isn't REF)
SOURCE_DATA_TYPE short => source type of a distinct type or user-generated Ref type,SQL type from java.sql.Types (null if DATA_TYPE isn't DISTINCT or user-generated REF)
