页面

								总金额: <%=dt.Compute("Sum(jexx)","") %>元
								合计:

后台

 dt = SqlEasy.ExecuteDataTable("Select * FROM (SELECT ROW_NUMBER()Over(order by o.KeyId desc) as rowId," + sql + " from jydOrder as o,jydOrderDetail as od where od.orderid=o.OrderID "+searchSql+") as mytable WHERE rowId between " + start + " and " + end + "");
