hi,
thanks for your reply, i tried to use your idea but it still give me an error which i couldn't understand it.
is it ok if i use the code below to convert a String to Date.
          java.sql.Date PickDat = java.sql.Date.valueOf(PDate);
          java.sql.Date DropDat = java.sql.Date.valueOf(DDate);
          System.out.println("IN CARINFO FUNC." + pickdropPnt + PDate + DDate + carclass);
               sql.append("SELECT * FROM CARS");
               sql.append("WHERE TO_DAYS('" PickDat "') BETWEEN TO_DAYS('FROM_D') AND TO_DAYS('UNTIL_D') ");
               sql.append("AND TO_DAYS('" DropDat "') BETWEEN TO_DAYS('"+PickDat+"') AND TO_DAYS('UNTIL_D') ");
               sql.append("AND PICK_UP_DROP ='" + pickdropPnt +"' ");
               sql.append("AND CAR_TYPE ='"+carclass + "'");
thanks for your help
