如果单元格是等效的，则为另一列的SUM的列

Question

我正在构建一个相对复杂的查询：

SELECT ROW_NUMBER() OVER (
        ORDER BY TSK.[Status] DESC
        ) AS 'RowNumber'
    ,PDT.[Name] AS Project
    ,(
        CASE 
            WHEN (
                    STY.KanBanProductId IS NOT NULL
                    AND STY.SprintId IS NULL
                    )
                THEN 'KanBan'
            WHEN (
                    STY.KanBanProductId IS NULL
                    AND STY.SprintId IS NOT NULL
                    )
                THEN 'Sprint'
            END
        ) AS ProjectType
    ,STY.[Number] StoryNumber
    ,STY.Title AS StoryTitle
    ,TSK.[Name] AS Task
    ,CONVERT(VARCHAR(20), STY.Effort) AS StoryPoints

    ,CONVERT(VARCHAR(20), TSK.OriginalEstimateHours) AS TaskHoursEstimate
    ,ISNULL(SUM(DTH.[Hours]), 0) AS WorkHours
    ,MAX(CASE 
            WHEN DTH.Hours != 0
                THEN DTH.ActivityDate
            END) AS LatestActivityDate
    ,TSK.[Status] AS [Status]
FROM Task TSK
LEFT JOIN DailyTaskHours DTH ON TSK.PK_Task = DTH.TaskId
LEFT JOIN Story STY ON TSK.StoryId = STY.PK_Story
LEFT JOIN Sprint SPT ON STY.SprintId = SPT.PK_Sprint
LEFT JOIN Product PDT ON STY.ProductId = PDT.PK_Product
WHERE TSK.PointPerson LIKE @userParam
    AND TSK.[Status] LIKE @statusParam
    AND PDT.[Name] != 'Overhead Codes'
GROUP BY LEN(STY.[Number])
    ,STY.[Number]
    ,TSK.[Status]
    ,STY.Title
    ,PDT.[Name]
    ,TSK.CreateDate
    ,TSK.[Name]
    ,STY.KanBanProductId
    ,STY.SprintId
    ,TSK.OriginalEstimateHours
    ,STY.Effort
ORDER BY CASE TSK.[Status]
        WHEN 'Not Started'
            THEN 1
        WHEN 'In Progress'
            THEN 2
        WHEN 'Impeded'
            THEN 3
        WHEN 'Done'
            THEN 4
        END

我想为同一个StoryNumber（STY。[Number]）添加一个对TaskHoursEstimate列（TSK.OriginalEstimateHours）求和的行。以下是一个例子：

突出显示的部分显示了我的意思。我想添加一行，因为storyNumber对于这3行（SPK01-22）是相同的，所以每行中有48行（24 + 16 + 8）。

我如何实现这一目标？

我能够弄清楚。我使用了SELECT子查询：

SELECT ROW_NUMBER() OVER (
        ORDER BY TSK.[Status] DESC
        ) AS 'RowNumber'
    ,TSK.PointPerson AS PointPerson
    ,PDT.[Name] AS Project
    ,(
        CASE 
            WHEN (
                    STY.KanBanProductId IS NOT NULL
                    AND STY.SprintId IS NULL
                    )
                THEN 'KanBan'
            WHEN (
                    STY.KanBanProductId IS NULL
                    AND STY.SprintId IS NOT NULL
                    )
                THEN 'Sprint'
            END
        ) AS ProjectType
    ,STY.[Number] StoryNumber
    ,STY.Title AS StoryTitle
