SQL学习笔记9——分页查询

--每页三条  查第五页的
select * from
(select 编号=ROW_NUMBER() over(order by tsname desc),* from student)as newStu
where newStu.编号 between (5-1)*3+1 and 3*5

--每页9条数据 查询13页的
select * from
(select 编号=ROW_NUMBER() over(order by id),* from MyOrders) as Orders
where 编号 between (13-1)*9+1 and 13*9

--第一种：分页的方法sql
--一页 ：3条   第四页
-- 越过多少条（2-1）*3   取多少条 3
--select top 3  * from UserInfo where UserId not in
--(
--	select top ((4-1)*3) UserId from UserInfo order by UserId
--) --越过的数据的id的集合
--order by UserId

--第二种：分页sql  一页3条， 取第 4页
--select * from (
--	select  *,ROW_NUMBER() over(order by userid) as num  from UserInfo
--) as T
--where T.num between ((4-1)*3+1) and  (4*3)
