          一 前提
          希望最新的紀錄在開頭給你的表建立查詢:
          表:mytable
          查詢:create or replace view as mytable_view from mytable order by id desc 其中,最好使用序列號create sequence mytable_sequence 來自動增加你的紀錄id號

          二 源程序
          <%String sConn="你的連接"
          Class.forName("oracle.jdbc.driver.OracleDriver");
          Connection conn=DriverManager.getConnection(sConn,"你的用戶名","密碼");
          Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENS99vIVE,ResultSet.CONCUR_UPDATABLE);
          Statement stmtcount=conn.createStatement(ResultSet.TYPE_SCROLL_SENS99vIVE,ResultSet.CONCUR_UPDATABLE);

          ResultSet rs=stmt.executeQuery("select * from mytable_view");
          String sqlcount="select count(*) from mytable_view";
          ResultSet rscount=stmtcount.executeQuery(sqlcount);

          int pageSize=你的每頁顯示紀錄數;
          int rowCount=0; //總的記錄數
          while (rscount
          int pageCount; //總的頁數
          int currPage; //當前頁數

          1


          String strPage;
          strPage=request.getParameter("page");
          if (strPage==null){
          currPage=1;
          }
          else{
          currPage=Integer.parseInt(strPage);
          if (currPage<1) currPage=1;
          }
          pageCount=(rowCount+pageSize-1)/pageSize;
          if (currPage>pageCount) currPage=pageCount;

          int thepage=(currPage-1)*pageSize;
          int n=0;
          rs.absolute(thepage+1);
          while (n<(pageSize)&&!rs
          %>
          <%rs.close();
          rscount.close();
          stmt.close();
          stmtcount.close();
          conn.close();
          %>

          //下面是 第幾頁等
          <form name="sinfo" method="post" action="sbinfo_index.jsp?condition=<%=condition%>&type=<%=type%>" onSubmit="return testform(this)">
          第<%=currPage%>頁 共<%=pageCount%>頁 共<%=rowCount%>條
          <%if(currPage>1){%><a href="sbinfo_index.jsp?condition=<%=condition%>&type=<%=type%>">首頁</a><%}%>
          <%if(currPage>1){%><a href="sbinfo_index.jsp?page=<%=currPage-1%>&condition=<%=condition%>&type=<%=type%>">上一頁</a><%}%>
          <%if(currPage<pageCount){%><a href="sbinfo_index.jsp?page=<%=currPage+1%>&condition=<%=condition%>&type=<%=type%>">下一頁</a><%}%>
          <%if(pageCount>1){%><a href="sbinfo_index.jsp?page=<%=pageCount%>&condition=<%=condition%>&type=<%=type%>">尾頁</a><%}%>
          跳到<input type="text" name="page" size="4" style="font-size:9px">頁
          <input type="submit" name="submit" size="4" value="GO" style="font-size:9px">
          </form>
