使用ROW_NUMBER()方法查询结果集；语句如下：
select ROW_NUMBER() OVER(ORDER BY dbo.OrderOutProduct.ID) AS RowNumber,dbo.Order.ID,Telephone,AddressCity,Province, from dbo.Order
inner join dbo.Order2
on dbo.Order.ID=Order2ID
inner join dbo.Order3
on dbo.Order2.OrderID=dbo.Order3.Order3
where Service=1 and RowNumber=1但是出现了错误：列名 'RowNumber' 无效。
查到网上给的解释是：在sql里这个叫做，热名称，刚定的不能立马使用！要包一层查询！
修改为：
select * from(
select ROW_NUMBER() OVER(ORDER BY dbo.OrderOutProduct.ID) AS RowNumber,
dbo.Order.ID,Telephone,AddressCity,Province, from dbo.Order
inner join dbo.Order2
on dbo.Order.ID=Order2ID
inner join dbo.Order3
on dbo.Order2.OrderID=dbo.Order3.Order3
where Service=1
)U where RowNumber=1
