小编use*_*464的帖子

当我运行第一个查询时，一切运行正常：

select uid,
(select top 1 city from UserData where UserData.uid = #uids.uid 
group by city)
from #uids;

问题是当我添加时order by count(city)，出现错误：由于内部错误，不支持这种类型的相关子查询模式

select uid,
(select top 1 city from UserData where UserData.uid = #uids.uid 
group by city
order by count(city))
from #uids;
