sql - 按底部的某个字符串排序，然后按不同列的字母顺序

Question

我正在尝试订购查询，但没有得到所需的结果:

SELECT R.[Name] AS Project, ISNULL(P.[Name]+' - '+P.[Description], 'KanBan') AS Sprint, S.[Number] AS Story, T.[Name] AS Task,
   sum(CASE WHEN DatePart(dw, D.ActivityDate) = 1 THEN D.[Hours] ELSE 0 END) AS Monday,
   sum(CASE WHEN DatePart(dw, D.ActivityDate) = 2 THEN D.[Hours] ELSE 0 END) AS Tuesday,
   sum(CASE WHEN DatePart(dw, D.ActivityDate) = 3 THEN D.[Hours] ELSE 0 END) AS Wednesday,
   sum(CASE WHEN DatePart(dw, D.ActivityDate) = 4 THEN D.[Hours] ELSE 0 END) AS Thursday,
   sum(CASE WHEN DatePart(dw, D.ActivityDate) = 5 THEN D.[Hours] ELSE 0 END) AS Friday,
   sum(CASE WHEN DatePart(dw, D.ActivityDate) = 6 THEN D.[Hours] ELSE 0 END) AS Saturday,
   sum(CASE WHEN DatePart(dw, D.ActivityDate) = 7 THEN D.[Hours] ELSE 0 END) AS Sunday
FROM DailyTaskHours D
INNER JOIN Task T ON D.TaskId = T.PK_Task 
INNER JOIN Story S ON T.StoryId = S.PK_Story 
LEFT JOIN Sprint P ON S.SprintId = P.PK_Sprint 
INNER JOIN Product R ON S.ProductId = R.PK_Product
GROUP BY R.[Name], P.[Name], P.[Description], S.[Number], T.[Name]
ORDER BY CASE WHEN (P.[Name]+' - '+P.[Description]) = 'KanBan' then 1 else 0 end, Project ASC, Story ASC, Task ASC

首先，我想要 P.[Name]+' - '+P.[Description] 为 NULL 并且用“KanBan”填充到底部，然后按产品的字母顺序排列，然后在产品后冲刺，然后是故事，然后是任务。

我怎样才能做到这一点？

编辑:谢谢这里是最后的查询:

SELECT R.[Name] AS Project, ISNULL(P.[Name]+' - '+P.[Description], 'KanBan') AS Sprint, S.[Number] AS Story, T.[Name] AS Task,
   sum(CASE WHEN DatePart(dw, D.ActivityDate) = 1 THEN D.[Hours] ELSE 0 END) AS Monday,
   sum(CASE WHEN DatePart(dw, D.ActivityDate) = 2 THEN D.[Hours] ELSE 0 END) AS Tuesday,
   sum(CASE WHEN DatePart(dw, D.ActivityDate) = 3 THEN D.[Hours] ELSE 0 END) AS Wednesday,
   sum(CASE WHEN DatePart(dw, D.ActivityDate) = 4 THEN D.[Hours] ELSE 0 END) AS Thursday,
   sum(CASE WHEN DatePart(dw, D.ActivityDate) = 5 THEN D.[Hours] ELSE 0 END) AS Friday,
   sum(CASE WHEN DatePart(dw, D.ActivityDate) = 6 THEN D.[Hours] ELSE 0 END) AS Saturday,
   sum(CASE WHEN DatePart(dw, D.ActivityDate) = 7 THEN D.[Hours] ELSE 0 END) AS Sunday
FROM DailyTaskHours D
INNER JOIN Task T ON D.TaskId = T.PK_Task 
INNER JOIN Story S ON T.StoryId = S.PK_Story 
LEFT JOIN Sprint P ON S.SprintId = P.PK_Sprint 
INNER JOIN Product R ON S.ProductId = R.PK_Product
GROUP BY R.[Name], P.[Name], P.[Description], S.[Number], T.[Name]
ORDER BY CASE WHEN ISNULL(P.[Name]+' - '+P.[Description], 'KanBan') = 'KanBan'
    THEN 1
    ELSE 0 END,
    Project ASC,
    Sprint ASC,
    Story ASC,
    Task ASC

Answer 1

只需要稍微修改一下:

ORDER BY CASE WHEN ISNULL(P.[Name]+' - '+P.[Description], 'KanBan') = 'KanBan'
    THEN 0
    ELSE 1 END

问题是您永远不会收到 KanBan在您的 ORDER BY条款。
