          "user id=db2admin;server=db2;database=SAMPLE;");
      DB2Script db2Script = new DB2Script(script,db2Conn);
      db2Script.Progress += new Devart.Common.ScriptProgressEventHandler(OnProgress);
      db2Script.Error += new Devart.Common.ScriptErrorEventHandler(OnError);
      db2Conn.Open();
      db2Script.Execute();
