T-SQL查询前十条数据相关操作

 

--求某时间段内平均值的前十条的总和

SELECT SUM(Result)

FROM (

           SELECT TOP 10 AVG(Result) AS result 

	   FROM B_Record_DomainNamePage

	   WHERE RecordTime BETWEEN '2010-12-16 13:11:27' AND '2010-12-22 13:11:27'

           GROUP BY Page

           ORDER BY Result DESC

        ) AS temp

 

 

--求除去前十条的某列的总和

SELECT SUM(result)

FROM (

	  SELECT *,ROW_NUMBER() OVER(ORDER BY Result DESC) AS rownum 

	  FROM B_Record_DomainNamePage 

	  WHERE RecordTime BETWEEN '2010-12-16 13:11:27' AND '2010-12-22 13:11:27'

         ) AS temp

WHERE rownum>10



--或者用存储过程实现

ALTER PROC [dbo].[SP_test]	

	as

	begin

	declare @sumall int

	declare @sumother int

	

	select @sumall = sum(result) from B_Record_DomainNamePage

	where RecordTime between '2010-12-16 13:11:27' and '2010-12-22 13:11:27')

	

	select @sumother =sum(result) from 

         (

            select top 10 result 

            from B_Record_DomainNamePage 

            where RecordTime between '2010-12-16 13:11:27' and '2010-12-22 13:11:27'

            ORDER by result desc

         ) as aa



	select @sumall-@sumother

	end 





--执行存储过程

DECLARE	@return_value int



EXEC	@return_value = [dbo].[SP_test]



SELECT	'Return Value' = @return_value
