使用ROW_NUMBER()查询：列名 'RowNumber' 无效。

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
