分页语句

取出sql表中第31到40条的记录（以自动增长ID为主键）：

Sql Server 下:

方案1：select top 10 * from t where  id not in (select top 30 id form t order by id) order by id;

方案2：select top 10 * from t where id in (select top 40 id from t order by id) order by id desc;

MySql 下：

select * from t order by id limit 30,10;

Oracle 下：

select * from (select rownum r,* from t where r<40） where r>30;
