Question

我的查询是：

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'

错误：

ORDER BY子句在视图，内联函数，派生表中无效，子查询和公用表表达式，除非还指定了TOP或FOR XML。

如何在子查询中使用ORDER BY？

尝试使用如下窗口功能

    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
