SQL2005 新增函数Row_number() 存储过程分页有大用

---------判断是否有这个存储过程名称，有就删除
IF EXISTS (SELECT * FROM sysobjects WHERE type = 'P' AND name = 'PR_Page_Rownumber')
BEGIN
DROP  Procedure  PR_Page_Rownumber
END
----------end

----------新建存储过程

GO

create procedure PR_Page_Rownumber --利用SQL 2005中的Row_number()  SQL2000没有该函数
(
@tableName varchar(50),
@pageIndex int,
@pageSize int,
@sort varchar(50)
)
as
declare @timediff datetime
begin
set nocount on;
select @timediff=getdate()
select * from (select *,Row_number() over(order by @sort ) as IDRank from @tableName) as IDWithRowNumber where IDRank>(@pageSize*(@pageIndex-1)) and IDRank<=@pageSize*@pageIndex
select datediff(ms,@timediff,getdate()) as 耗时
set nocount off;
end

GO
