一:

1:select * from (select rownum rn ,* from 表名 where?rownum<20?) a?

?where a.rn>10

2:select * from 表名 where rownum<20

minus
select * from 表名 where rownum<10
?

二:SqlServer

1:select top 20 * from tablename where id not?exists (select top?10 * from tablename)//前20条记录再过滤掉前10条
2:select top10 * from (select top 20 * from order by column) order by column desc//子查询中取20条倒序,然后从子查询中取前10条

三:

select * from tablename where LIMIT 9,10
