-- 里层数据排序成功，到外层包一层row_id失效了
select * from (
	select top 100 percent  
		ROW_NUMBER() over (order by GETDATE() ) as row_id , 
		* 
		from  [test].[dbo].[table_01]  
		where  [id] > 1  
		order by [id] desc  
		) as t
		
	where t.row_id > 0 and 
		  t.row_id <=500 
	 
	 


-- 分页order by 失效
select * from (
		 select  top 100 percent 
			ROW_NUMBER() over ( order by GETDATE() ) as row_id , 
			t1.* 
			from ( select  * from  [test].[dbo].[table_01]  ) as t1  order by t1.id  desc

子句中from 后面的order by 是无效的
