如何按列而不在select子句中排序？

Question

有沒有一種方法可以解決無法按select子句中的列排序的問題？ 我使用日期名稱來獲取月份和年份，但我需要按實際日期而不是按字母順序對其進行排序。

select   datename(month, dbo.ITR.ITR_TransDate) as MonthDt, 
        DATENAME(year, dbo.itr.ITR_TransDate) as YearDt, COUNT(distinct dbo.ITR.ITR_Reason) AS WKCount, COUNT(dbo.itr.itr_reason) AS LineCt 
        from dbo.ITR
where   (ITR_EmployeeID IN (N'robra', N'lewer', N'petam', N'whike', N'mclch', N'ricju')) AND    (dbo.ITR.ITR_TransDate >= '1/1/13' AND dbo.itr.ITR_TransDate <= '1/31/14') AND 
    (dbo.itr.ITR_Reason LIKE 'WO%' OR dbo.itr.ITR_Reason LIKE 'RW%')
group by DATENAME(year, dbo.itr.ITR_TransDate), datename(month, dbo.ITR.ITR_TransDate), MONTH(dbo.itr.itr_transdate)
order by dbo.ITR.ITR_TransDate

我所擁有的訂單無法通過b / c預訂，因此不在分組依據中或不在匯總中。 我不能將其添加到任何一個B / C中，它將返回許多日期。

Answer 1

您可以按以下order by使用聚合函數：

order by min(dbo.ITR.ITR_TransDate)

這應該適合您的情況。

Answer 2

嘗試這個

select   datename(month, dbo.ITR.ITR_TransDate) as MonthDt, 
    DATENAME(year, dbo.itr.ITR_TransDate) as YearDt, COUNT(distinct dbo.ITR.ITR_Reason) AS WKCount, COUNT(dbo.itr.itr_reason) AS LineCt 
    from dbo.ITR
where   (ITR_EmployeeID IN (N'robra', N'lewer', N'petam', N'whike', N'mclch', N'ricju')) AND    (dbo.ITR.ITR_TransDate >= '1/1/13' AND dbo.itr.ITR_TransDate <= '1/31/14') AND 
(dbo.itr.ITR_Reason LIKE 'WO%' OR dbo.itr.ITR_Reason LIKE 'RW%')
group by DATENAME(year, dbo.itr.ITR_TransDate), datename(month, dbo.ITR.ITR_TransDate), MONTH(dbo.itr.itr_transdate)
order by DATENAME(year, dbo.itr.ITR_TransDate), MONTH(dbo.itr.itr_transdate)
