sql取前20条数据的后10条数据（通用）

来源：互联网发布：acca教材淘宝编辑：程序博客网时间：2024/05/16 15:17

SQL在没有ID主键或单一主键(即组合主键或没有主键的情况)，如何取前20条数据的后10条数据，一般通用的方法仍是用临时表，效率一般，但比较通用，在各种情况下均可用此方法...由此也可衍生出SQL的分页存储过程，尤其适合经常对不同表的数据进行分页，格外适用.

当然，方法并非这一种，具体视不同情况设计最优的sql语句或存储过程.但思想是想通的...

--start
create table T
(
T01 varchar(20),
T02 char(10),
T03 datetime
)

insert into T values ('601','801','2009-12-23')

insert into T values ('602','802','2009-12-22')

insert into T values ('603','803','2009-12-21')

insert into T values ('604','804','2009-12-20')

insert into T values ('605','805','2009-12-24')

insert into T values ('606','806','2009-12-25')

insert into T values ('607','807','2009-12-23')

insert into T values ('608','808','2009-12-22')

insert into T values ('609','809','2009-12-21')

insert into T values ('610','810','2009-12-22')

select identity(int,1,1) as T05,* into #T from T

select *
from
(
select top 8 *
    from #T
) as T1
where
T05
not in
(
select top 3 T05
from
(
    select top 8 *
    from #T
) as T2
)
--end
