sql 查询记录数结果集某个区间内记录

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.
