display the descriptionpstmt.setRef(1, resort);rset = pstmt.executeQuery();rset.next();System.out.println(" beach description of first resort afterupdate: " +rset.getString(1));rset.close();pstmt.close();stmt.close();conn.close();}}The previous example shows the following steps that an application mustperform in order to use the ordbObject methods to insert and/or update adatabase instance:1. Acquire an ordbObject (either existing object for update, or using theordbObject(Connection, className) constructor for insert).2. Make calls to setAttributeValue() method to update the attributes of theobject. These updates are actually performed on a template of thedatabase instance.3. Call updateInstance() method to transmit the changes to the database. Thiswill result in an insert of a new object, or the update of an existing objectdepending on how the ordbObject instance was acquired in step 1.JDBC Developer's Guide, P25-9504-03 Page 35Chapter: 4.
