sqlserver 分页的方法

sqlserver2000时的分页思路

1.分页查询时，首先将数据排序

    select * from MyStudent order by fid desc

2.取第一页数据

    select Top 5 * from MyStudent order by fid desc

3.取第二页数据

    select Top 5 * from MyStudent

    where fid not in

    (

        select Top 5 * from MyStudent order by fid desc

    )

    order by fid desc

4.取第三页的数据

    select Top 5 * from MyStudent

    where fid not in

    (

        select Top (2*5) * from MyStudent order by fid desc

    )

    order by fid desc

4.取第四页的数据

    select Top 5 * from MyStudent

    where fid not in

    (

        select Top (3*5) * from MyStudent order by fid desc

    )

    order by fid desc

    
sqlserver2005时的分页思路    

--第7页数据

select * from

(

    select *,row_number() over(order by fid desc) as runumber

    from MyStudent

) as tbl

where tbl.rnumber between 6*5+1 and 7*5

--第20页数据

select * from

(

    select *,row_number() over(order by fid desc) as runumber

    from MyStudent

) as tbl

where tbl.rnumber between 19*5+1 and 20 *5

--开窗函数与聚合函数一起使用，可以让聚合函数对每一条数据都计算一次

select *,count(*) over() as 总条数 from MyStudent
