sql分页的几种写法

sql分页的几种写法

几种典型的分页sql，下面例子是每页50条，198*50=9900，取第199页数据。
--写法1，not in/top
select top 50 * from pagetest
where id not in (select top 9900 id from pagetest order by id)
order by id

--写法2，not exists
select top 50 * from pagetest
where not exists
(select 1 from (select top 9900 id from pagetest order by id)a where a.id=pagetest.id)
order by id

--写法3，max/top
select top 50 * from pagetest
where id>(select max(id) from (select top 9900 id from pagetest order by id)a)
order by id

--写法4，row_number()
select top 50 * from
(select row_number()over(order by id)rownumber,* from pagetest)a
where rownumber>9900

select * from
(select row_number()over(order by id)rownumber,* from pagetest)a
where rownumber>9900 and rownumber<9951

select * from
(select row_number()over(order by id)rownumber,* from pagetest)a
where rownumber between 9901 and 9950

--写法5，在csdn上一帖子看到的，row_number() 变体，不基于已有字段产生记录序号，先按条件筛选以及排好序，再在结果集上给一常量列用于产生记录序号
select * from (
select row_number()over(order by tempColumn)rownumber,*
from (select top 9950 tempColumn=0,* from pagetest where 1=1 order by id)a
)b
where rownumber>9900
