custom mapped class, then.// 5. Invokes the readSQL() method (of the SQLData// interface) on the custom class.// (The SQLData interface must be implemented by a custom// class.)// 6. When readSQL is done, the java instance will be// populated with the attribute data from the database.System.out.println("beach description of resort " +rset.getString(1) + " :" + beach.description);}...Using the ordbObject.getObject methodThe ordbObject class also supports the getObject method. When you call thegetObject method of an instance of ordbObject, the JDBC driver willmaterialize the database object referenced by the ordbObject as an instanceof the custom mapped java class. If the type map (either the default, or passedas a parameter) does not contain a mapping for the database class that theordbObject is an instance of, then the getObject method will return theordbObject as a java.sql.Struct (via a cast).The following example assumes that the default type map associates thedatabase class “seashore” with the java class jseashore, and the database class“resort” with the java class jresort:ResultSet rset = stmt.executeQuery ("SELECT resort.IDENTITY resortWHERE beach IS NOT NULL");jresort resort = null;while (rset.next ()) {resort = rset.getObject(1));jseashore seashore = resort.beach.getObject();System.out.println("beach description of resort " +resort.name + " :" + seashore.description);}...JDBC Developer's Guide, P25-9504-03 Page 51Chapter: 4.
