比方说有2个字段  1个是时间 1个是id
id  time




我想先order by id  

3 444
3 555

2   222
2  333

然后再order by time

变成
3 444
3 555

2   333
2  222

怎么写 注意   33  22 都分组来排序的


回复讨论(解决方案)

如果最后结果是这个,可以这样写 order by id desc,time desc
3 555
3 444
2 333
2 222

你的要求是否为:
奇数 id 的 time 升序
偶数 id 的 time 降序

如果是的话,则 order 子句为:
order by id desc, id%2
