Answer 1

目前还不清楚，但我认为你想这样的：

SELECT A.TotalPerMonth , 
     DATENAME(MONTH, DATEADD(MONTH, A.monthValue, -1)) AS month , 
     A.Year 
FROM (SELECT TOP 5 
        COUNT(pk_id) AS TotalPerMonth , 
        MONTH(VistorDate) AS monthValue , 
        YEAR(VistorDate) AS Year 
      FROM  jot.tbl_vistor 
      GROUP BY MONTH(VistorDate) , 
        YEAR((VistorDate)) 
      ORDER BY YEAR((VistorDate)) DESC , 
        MONTH(VistorDate) DESC 
     ) A 
ORDER BY A.Year , 
     A.monthValue 

即在子查询中，您按年份desc和月份desc订购最后5个月。在外部查询中，您按年份asc和月份asc排序。

Answer 2

试试这个：编辑

Select A.TotalPerMonth , DateName(month , DateAdd(month , A.monthValue , -1)) as month , A.Year 
from(Select Top 6 count(pk_id) as TotalPerMonth, 
month(VistorDate) as monthValue, 
Year(VistorDate) as Year 
from jot.tbl_vistor 
group by month(VistorDate) ,YEAR((VistorDate)) 
order by VistorDate desc) A 
order by A.monthValue , A.Year ASC 

你需要指定A.monthValue DESC 。你忘了把DESC放在那里。

Answer 3

试试这个：

Select A.TotalPerMonth , DateName(month, DateAdd(month , A.monthValue , -1)) as month , A.Year from(
Select Top 6 count(pk_id) as TotalPerMonth, month(VistorDate) as monthValue, Year(VistorDate) as Year 
from jot.tbl_vistor 
group by month(VistorDate) ,YEAR((VistorDate)) 
order by YEAR((VistorDate)) desc, month(VistorDate) 
) A order by A.Year, A.monthValue 

Answer 4

我通过完整的日期排序解决它。要做到这一点，我从产生一个monthValue和DATETIMEYear

Select DateName(month , DateAdd(month , A.monthValue , -1)) as month , A.Year 
from(SELECT Top 5 
month(t.TestDate) as monthValue, 
Year(t.TestDate) as Year 
from #test t 
group by month(t.TestDate), YEAR(TestDate) 
order by month(t.TestDate), YEAR(TestDate) desc) A order BY CAST(CAST(A.monthValue AS varchar) + '-' + CAST(A.Year AS varchar) + '-01' AS DATETIME) ASC 

输出：
