导读：以查询前20到30条为例,主键名为id 方法一: 先正查,再反查 select top 10 from (select top 30 from tablename order by id asc) A order by id desc 方法二: 使用left join select top 10 A. from tablename A left outer join (select top 20 from tablenam

以查询前20到30条为例,主键名为id

方法一: 先正查,再反查

select top 10 from (select top 30 from tablename order by id asc) A order by id desc

方法二: 使用left join

select top 10 A. from tablename A
left outer join (select top 20 from tablename order by id asc) B
on A.id = B.id
where B.id is null
order by A.id asc

方法三: 使用not exists

select top 10 from tablename A
where id not exists
(select top 20 from tablename B on A.id = B.id)

方法四: 使用not in

select top 10 * from tablename
where id not in
(select top 20 id from tablename order by id asc)
order by id asc

方法五: 使用rank()

select id from
(select rank() over(order by id asc) rk,id from tablename) T
where rk between 20 and 30 中第五种方法看上去好像没有问题,查了下文档,当over()用于rank/row_number时,整型列不能描述一个列,所以会产生非预期的效果. 待考虑下,有什么办法可以修改为想要的结果.
