二、以下示例将返回行号为 50 到 60（含）的行，并以 OrderDate 排序。
USE AdventureWorks;
GO
WITH OrderedOrders AS
(SELECT SalesOrderID, OrderDate,
ROW_NUMBER() OVER (order by OrderDate)as RowNumber
FROM Sales.SalesOrderHeader )
SELECT *
FROM OrderedOrders
WHERE RowNumber between 50 and 60;
三、实现分页存储过程(固定到某个表的数据)
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
