所有作業的SUM

Question

我有一個SQL語句，我試圖爲所有JobTypes提取總和，例如，如果有5個名稱爲「Process」的作業，它們應該只在一行上顯示Sum GB和KB。我該如何做到這一點？謝謝。

，所以我將顯示： - jpavlov 10分鐘前
2012年12月1日，數據Extrat，總和（60），和（56） - jpavlov 8分鐘前
2012年12月1日，流程，和（60 ），和（56）

SELECT 

Jobs.DateCompleted AS 'DateCompleted', 
JobTypes.Name AS 'JobName', 
SUM(Metrics.GB) AS GB, 
SUM(Metrics.KB) AS KB 
FROM Metrics 

INNER JOIN 
Jobs ON Jobs.JobId = Metrics.JobId 
INNER JOIN 

Projects ON Projects.ProjectId = Jobs.ProjectId 

INNER JOIN 
JobTypes ON JobTypes.JobTypeId = Jobs.JobTypeId 

WHERE Jobs.DateCompleted 
Between '12/01/2012' AND '12/03/2012' 

GROUP BY 
Jobs.DateCompleted, 
JobTypes.Name 

2012-12-01 04:28:15.477 Data Extract 0.200 210903.738 
2012-12-01 04:40:07.913 Data Extract 0.781 819388.602 
2012-12-01 04:48:45.493 Data Extract 5.278 5538731.844 
2012-12-01 04:54:55.483 Data Extract 6.927 7265870.682 
2012-12-01 14:11:38.357 Export 13.189 13828648.369 
2012-12-01 16:57:54.840 Process 2.054 2156185.331 

Answer 1

刪除CAST (Jobs.DateCompleted AS VARCHAR(MAX))從SELECT以及GROUP BY。

假設：JobTypes.Name和JobTypes.JobTypeId有1到1的映射。

編輯

SELECT 
JobTypes.Name AS 'JobName', 
SUM(Metrics.GB) AS GB, 
SUM(Metrics.KB) AS KB 
FROM Metrics 

INNER JOIN 
Jobs ON Jobs.JobId = Metrics.JobId 
INNER JOIN 

Projects ON Projects.ProjectId = Jobs.ProjectId 

INNER JOIN 
JobTypes ON JobTypes.JobTypeId = Jobs.JobTypeId 

WHERE Jobs.DateCompleted 
Between '12/01/2012' AND '12/03/2012' 

GROUP BY 
JobTypes.Name 

對於結果通過Name場得到總結出來的，你必須將DateCompleted從Select刪除以及Group By。

EDIT2：

在this question看一看，修改SQL。

SELECT 
convert(varchar(10), Jobs.DateCompleted, 120) AS DateCompleted 
JobTypes.Name AS 'JobName', 
SUM(Metrics.GB) AS GB, 
..... 
..... 
GROUP BY 
convert(varchar(10), Jobs.DateCompleted, 120), 
JobTypes.Name
