数据库结果集的问题，哪位大侠看看。。。

Java code

public List<LetterInfo> letterInfosByletterReceiver(int page,String letterReceiver) {
         if(page<1) {
              page = 1;
          }else if(page>this.getInboxMaxPage(letterReceiver)) {
              page = this.getInboxMaxPage(letterReceiver);
          }
         List<LetterInfo> letterInfos = new ArrayList<LetterInfo>();
         String sql = "";
         sql="select top 8 letterid from letterreceiverinfo where letterreceiver='"+letterReceiver+"' and receiverinfoid not in(select top "+(page-1)*8+" receiverinfoid from letterreceiverinfo ) and isread=1";
         //System.out.println(sql);
         [color=#FF0000]ResultSet rs = connection.executeQuery(sql);[/color]
         try {
            [color=#FF0000]if(rs.next()) [/color]{
                rs.first();
                while(rs.next()) {
                    letterInfos.add(letterInfoDao.getLetterInfoById(rs.getInt(1)));
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
         return letterInfos;
    }
