The following example shows the difference between sensitive and insensitive ResultSets when rows are inserted into a table.
import java.sql.*; public class Sensitive { public Connection connection = null; public static void main(java.lang.String[] args) { Sensitive test = new Sensitive(); test.setup(); test.run("sensitive"); test.cleanup(); test.setup(); test.run("insensitive"); test.cleanup(); } public void setup() { try { Class.forName("com.ibm.db2.jdbc.app.DB2Driver"); connection = DriverManager.getConnection("jdbc:db2:*local"); Statement s = connection.createStatement(); try { s.executeUpdate("drop table cujosql.sensitive"); } catch (SQLException e) { // Ignored. } s.executeUpdate("create table cujosql.sensitive(col1 int)"); s.executeUpdate("insert into cujosql.sensitive values(1)"); s.executeUpdate("insert into cujosql.sensitive values(2)"); s.executeUpdate("insert into cujosql.sensitive values(3)"); s.executeUpdate("insert into cujosql.sensitive values(4)"); s.executeUpdate("insert into cujosql.sensitive values(5)"); s.close(); } catch (Exception e) { System.out.println("Caught exception: " + e.getMessage()); if (e instanceof SQLException) { SQLException another = ((SQLException) e).getNextException(); System.out.println("Another: " + another.getMessage()); } } } public void run(String sensitivity) { try { Statement s = null; if (sensitivity.equalsIgnoreCase("insensitive")) { System.out.println("creating a TYPE_SCROLL_INSENSITIVE cursor"); s = connection.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY); } else { System.out.println("creating a TYPE_SCROLL_SENSITIVE cursor"); s = connection.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_READ_ONLY); } ResultSet rs = s.executeQuery("select * From cujosql.sensitive"); // Fetch the five values that are there. rs.next(); System.out.println("value is " + rs.getInt(1)); rs.next(); System.out.println("value is " + rs.getInt(1)); rs.next(); System.out.println("value is " + rs.getInt(1)); rs.next(); System.out.println("value is " + rs.getInt(1)); rs.next(); System.out.println("value is " + rs.getInt(1)); System.out.println("fetched the five rows..."); // Note: If you fetch the last row, the ResultSet looks // closed and subsequent new rows that are added // are not be recognized. // Allow another statement to insert a new value. Statement s2 = connection.createStatement(); s2.executeUpdate("insert into cujosql.sensitive values(6)"); s2.close(); // Whether a row is recognized is based on the sensitivity setting. if (rs.next()) { System.out.println("There is a row now: " + rs.getInt(1)); } else { System.out.println("No more rows."); } } catch (SQLException e) { System.out.println("SQLException exception: "); System.out.println("Message:....." + e.getMessage()); System.out.println("SQLState:...." + e.getSQLState()); System.out.println("Vendor Code:." + e.getErrorCode()); System.out.println("-------------------------------------"); e.printStackTrace(); } catch (Exception ex) { System.out.println("An exception other than an SQLException was thrown: "); ex.printStackTrace(); } } public void cleanup() { try { connection.close(); } catch (Exception e) { System.out.println("Caught exception: "); e.printStackTrace(); } } }
