oracle 分页加排序
以前分页习惯用这样的SQL语句:
select * from
(select t.*,rownum row_num from mytable t order by t.id) b
where b.row_num between 1 and 10
结果发现由于该语句会先生成rownum 后执行order by 子句,因而排序结果根本不对,后来在GOOGLE上搜到一篇文章,原来多套一层select 就能很好的解决该问题,特此记录,语句如下:
select * from
(select a.*,rownum row_num from
(select * from mytable t order by t.id desc) a
) b where b.row_num between 1 and 10
