我有一个这样的问题

我想订购yw DESC，但以“nome”的子集为例

select YEARWEEK(v.dataorainizio,1) yw,pdv.nome ,pdv.localita
from visita v
join pdv on pdv.id=v.idpdv
order by yw DESC

在php中没有存储过程和后处理结果是可能的？

这就是您想要的吗

order by nome desc, yw desc
如果您想先将
nome
与最新的
yw
放在一起，那么假设MySQL 8.0，您可以使用窗口函数：

order by
    max(yearweek(v.dataorainizio,1)) over(partition by pdv.nome) desc,
    yearweek(v.dataorainizio,1) desc
抱歉，我用另一组数据再次检查了您的答案，结果与预期不符`202017（PDV CHIUSO）媒体世界那不勒斯2那不勒斯202017（PDV CHIUSO）媒体世界那不勒斯2那不勒斯202017（PDV CHIUSO）媒体世界诺拉诺拉202013（PDV CHIUSO）媒体世界那不勒斯2那不勒斯202012（PDV CHIUSO）媒体世界Nola Nola使用max（v.dataoranizio）而不是max（yearweek（v.dataoranizio，1））解决了问题谢谢
