以下日期排序查询有什么问题

Question

我使用以下查询对输出进行排序。它适用于某些情况但不是全部。输出图片给出。有什么建议吗？任何备用请。

Select 
    'playing' As activity,
    max(ad.xDate) As xDate,
    Isnull(sum(t.TimePerDay), 0) As TimePerDay 
From    
    AllDates As ad With (Nolock) 
Left Join 
    @test As t On ad.xDate = t.date
Group By
    datepart(wk, ad.xDate)
Order By
    YEAR(datepart(wk, ad.xDate)) DESC, MONTH(datepart(wk, ad.xDate)) DESC, DAY(datepart(wk, ad.xDate))

Answer 1

为什么要在获得年份和月份前提取一周？

我想你想要：

ORDER BY MIN(ad.xDate) DESC

这将按每行的任意日期排序。
