Question

我尝试执行以下操作（显然无法正常工作，因为我尝试按不在group by子句中的列进行排序），其中TransDateString是varchar列，定义为{{ TransDate（date）列的1}}。

cast(datepart(m,TransDate) as varchar)+'-'+cast(datepart(yyyy,TransDate) as varchar)

我想要完成的是按日期排序结果，但只返回列作为格式化字符串。

这里我要查找的数据和输出是：

SELECT c.TransDateString
        FROM #dataSet c
        GROUP BY c.TransDateString 
        ORDER BY c.TransDate asc

结果：

TransDate    |    TransDateString
2005-01-01   |    01-2005
2012-15-05   |    05-2012
2003-22-10   |    10-2003

;With cteRows As
(
SELECT c.TransDateString,
       Row_Number() Over (Partition By c.TransDateString Order By c.TransDate) RowNum
        FROM #dataSet c
)
Select TransDateString From cteRows Where RowNum = 1

没有CTE：

Select TransDateString From
(
Select c.TransDateString,
       Row_Number() Over (Partition By c.TransDateString Order By c.TransDate) RowNum
        FROM #dataSet c
) A
Where RowNum = 1

按日期排序但在SQL
