摘要SQL中的行

Question

我有一個存儲過程，它爲每個ActivityUnitId返回一組行。

需要的是基於小時數的每個ActivityUnitId的前10行。我已成功地做到這一點，我的查詢看起來像

With Data AS 
(SELECT 
    ProjectID,ActivityUnitID,Description,GroupID, 
    SUM(Hours) AS NoiseHours, 
    ROW_NUMBER() OVER(PARTITION BY ActivityUnitID ORDER BY SUM(Hours) DESC) as 'RowNum' 
FROM   
    tbl_Sub 
INNER JOIN 
    tbl_AnalysisData ON tbl_Sub.SubActivityID = tbl_AnalysisData.SubActivityID 
    INNER JOIN 
     tbl_Analysis ON tbl_AnalysisData.LookupID = tbl_Analysis.LookupID 
     INNER JOIN 
      tbl_ActivityUnit ON tbl_ActivityUnit.ActivityUnitID = tbl_Sub.ActivityUnitID 
      tbl_Suby.ProjectID = @ProjectID 
     AND 
      tbl_Sub.ActivityUnitID = ISNULL(@ActivityUnitID,tbl_Sub.ActivityUnitID) 
GROUP BY 
    ActivityUnitID,ProjectID, Description,AUGroupID 
) SELECT * from Data where RowNum<=10 

的「ROWNUM」列中包含行號的每一行，它的值是基於以小時分配。所以前10行包含前10個小時的行。

現在我想要的是爲每個ActivityUnitID添加額外的總結行。這將包含所有行被刪除的小時數的總和，即 RowNum> 10

所以我最終得到的是每個ActivityUnitID的前10行和額外的行總結一下其他行的時間爲ActivityUnitID

例如可以說我有2周的cols

表

ID Hours  RowNum 
1A 30   1 
2B 20   2 
3C 10   3 
4D  5   4 
5E  4   5 
6F  3   6 

我如何做這個選擇讓我得到行，其中ROWNUM < = 3和另一排與其他人的求和

ID Hours 
1A 30 
2B 20 
3C 10 
Oth 12

最簡單的方法是UNION與數據的彙總，你已經有

SELECT NULL, NULL, 'Totals', NULL, SUM(NoiseHours), 11 AS RowNumber 
FROM Data 
WHERE RowNum > 10 

你完整的陳述則可能是這個樣子

With Data AS 
(
SELECT ProjectID,ActivityUnitID,Description,GroupID, 
     SUM(Hours) AS NoiseHours, 
     ROW_NUMBER() OVER(PARTITION BY ActivityUnitID ORDER BY SUM(Hours) DESC) as 'RowNum' 
FROM   tbl_Sub 
      INNER JOIN 
      tbl_AnalysisData ON tbl_Sub.SubActivityID = tbl_AnalysisData.SubActivityID 
      INNER JOIN 
      tbl_Analysis ON tbl_AnalysisData.LookupID = tbl_Analysis.LookupID 
      INNER JOIN 
      tbl_ActivityUnit ON tbl_ActivityUnit.ActivityUnitID = tbl_Sub.ActivityUnitID 
tbl_Suby.ProjectID = @ProjectID 
AND 
tbl_Sub.ActivityUnitID = ISNULL(@ActivityUnitID,tbl_Sub.ActivityUnitID) 
GROUP BY ActivityUnitID,ProjectID, Description,AUGroupID 
) 
SELECT * from Data where RowNum<=10 
UNION ALL 
SELECT NULL, NULL, 'Totals', NULL, SUM(NoiseHours), 11 AS RowNumber 
FROM Data 
WHERE RowNum > 10 

的困難使用時工會認爲工會的兩個部門應該有相同數量和相同類型的專欄，因此需要添加虛擬列的選擇。
