import java.sql.*;

public class updateNull{

   public static void main(String [] args) {
   
      String strUrl = "jdbc:derby:;databaseName=testdb;create=true";
      try {

         Connection con = DriverManager.getConnection(strUrl);
         
         Statement stmt = con.createStatement();
         try {
            stmt.executeUpdate("drop table test");
         } catch(SQLException ex) {
            // Do nothing.
         }

         Statement stmt2 = con.createStatement();
         ResultSet rs = stmt2.executeQuery("select * from test");
         rs.next();
         rs.updateNull(2);
         rs.updateRow();
                  
      } catch(ClassNotFoundException cnfe) {
         System.out.println("Class not found: "+cnfe.getMessage());
      } catch(SQLException sqle) {
         System.out.println("SQL:Caught: "+sqle.getMessage());
         sqle.printStackTrace();
      } catch(Exception e) {
