如何在子查詢中使用ORDER BY？

Question

我的查詢是：

SET @query= 
    N'SELECT TaskID 
    ,Company 
    ,TaskSource 
    ,Urgency 
    ,Activity 
    ,StatusName 
    ,RequesterMailID 
    ,tsk.CreatedDate 
    ,tsk.LastUpdatedDate 
    ,LastUpdatedBy 
    ,(DATEDIFF(DAY, dbo.GetTimeByTimeZoneId(SLAStartTime, '' NZST ''), dbo.GetTimeByTimeZoneId(SLAActualEndTime, '' NZST ''))) 
     + 1 
     - count([Pact_OEMS].[dbo].[MstHolidays](HolidayDate)) AS AgeinDaystilldate 
FROM TaskMaster tsk 
LEFT OUTER JOIN TrnTaskReportDetails tsr ON tsk.TaskID = tsr.intTaskId 
FULL OUTER JOIN TrnSLADetails sla ON tsk.TaskID = sla.intTaskId 
FULL OUTER JOIN [Pact_OEMS].[dbo].[MstHolidays] ON [Pact_OEMS].[dbo].[MstHolidays].HolidayId = sla.intTaskId 
WHERE CreatedDate >= @FromDate 
    AND CreatedDate <= @ToDate 
    AND TaskID = @TaskID 
ORDER BY tsk.CreatedDate 
    ,tsk.LastUpdatedDate' 

和錯誤：

The ORDER BY clause is invalid in views, inline functions, derived tables, subqueries, and common table expressions, unless TOP or FOR XML is also specified.

我如何可以使用一個子查詢ORDER BY？

嘗試使用窗口函數像下面

SELECT TaskID, 
     Company, 
     TaskSource, 
     Urgency, 
     Activity, 
     StatusName, 
     RequesterMailID, 
     tsk.CreatedDate, 
     tsk.LastUpdatedDate, 
     LastUpdatedBy, 
     (DATEDIFF(DAY, dbo.GetTimeByTimeZoneId(SLAStartTime, '' NZST ''), dbo.GetTimeByTimeZoneId(SLAActualEndTime, '' NZST '')))+1-COUNT([Pact_OEMS].[dbo].[MstHolidays](HolidayDate)) AS AgeinDaystilldate, 
     ROW_NUMBER() OVER (PARTITION BY TaskID ORDER BY tsk.CreatedDate, 
                 tsk.LastUpdatedDate) rNO 
FROM TaskMaster tsk 
    LEFT OUTER JOIN TrnTaskReportDetails tsr ON tsk.TaskID = tsr.intTaskId 
    FULL OUTER JOIN TrnSLADetails sla ON tsk.TaskID = sla.intTaskId 
    FULL OUTER JOIN [Pact_OEMS].[dbo].[MstHolidays] ON [Pact_OEMS].[dbo].[MstHolidays].HolidayId = sla.intTaskId 
WHERE CreatedDate >= @FromDate 
     AND CreatedDate <= @ToDate 
     AND TaskID = @TaskID
