Working with Cincom ORDB objects and object referencesThis section has these subsections:♦ Accessing attribute values♦ Inserting, deleting, and updating database instances♦ Invoking database methodsWithin the Cincom ORDB JDBC Driver, database object references arerepresented by an instance of a class (or an instance of a subclass) ofordbjava.jdbc.ordbObject.Accessing attribute valuesIn JDBC, the java.sql.Ref interface handles the object references. TheordbObject class implements the java.sql.Ref interface allowing generic JDBCapplications to access and deal with object references without ever importingordbjava.jdbc.ordbObject into the application.The following sample code shows a generic JDBC application retrieving thebeach attribute (reference to a seashore object) from class resort, and thenaccessing the description from the seashore reference.Most of the remaining examples in this manual make use of a helperclass named demodbHelper to perform database connections. Thesource for the demodbHelper class is also included in your installation.This sample code may be found in the%ORDB%\demo\jdbc\samples\preparedStmtSample.java file://// This is a simple preparedStatement example//package demo.jdbc.samples;import java.sql.*;import java.math.*;import java.io.*;class preparedStmtSample {public static void main (String args []) throws SQLException{// Connect to the demodb database without autocommit enabled.Connection conn = demodbHelper.makeConnection (args, false);JDBC Developer's Guide, P25-9504-03 Page 31Chapter: 4.
