SQL Server的樞軸查詢添加低於總

Question

您好是SQL Server樞軸查詢其給出類似的輸出：A，B，C，d的

Semester| StudentDesc | [A]| [B] |[C] |[D] 
----------------------------------------- 
| 2 | Term1 | 20 | NULL| 5 | 10 
------------------------------------------ 
| 3  | Term2  | 10 | 2 | 2 | 1 
----------------------------------------- 

我將輸出到包括總共（TotalSessions）如：

Semester| StudentDesc | [A]| [B] |[C] |[D] | TotalSessions 
--------------------------------------------------------- 
| 2 | Term1 | 20 | NULL| 5 | 10 | 35 
-------------------------------------------------------- 
| 3  | Term2  | 10 | 2 | 2 | 1 | 15 
------------------------------------------------------- 

我認爲這將是AS查詢TotalSessions稱爲 計數（Stats.SessionNumber）列

查詢我擁有的是：

SELECT Semester, StudentDesc, [A],[B],[C],[D] 
FROM 
(
SELECT 
Semesters.Semester, Options.StudentDesc, 
/*TotalSessions */ Count(Stats.SessionNumber) AS  
TotalSessions,  TrainerList.ShortName 
FROM Semesters, (StudentList_tbl 
INNER JOIN              
((RegistrarSemestersAndTerms 
INNER JOIN 
Stats ON (StudentSemestersAndTerms.Semester = Stats.Semester) 
AND (StudentSemestersAndTerms.StudentID = Stats.StudentID)) 
INNER JOIN 
Options ON StudentSemestersAndTerms.Q3 = Options.TermID) 
ON StudentList_tbl.StudentID = StudentSemestersAndTerms.StudentID) 
INNER JOIN 
TrainerList ON StudentList_tbl.RTP = TrainerList.TrainerID 
GROUP BY Semesters.Semester, Options.StudentDesc, TrainerList.ShortName 
) as base_query 
PIVOT 
(
Sum(TotalSessions) FOR ShortName IN ([A],[B],[C],[D]) 
) as pivot_query; 

感謝

Answer 1

只是作爲WIRTE：

SELECT Semester, StudentDesc, [A],[B],[C],[D], 
isnull([A],0)+isnull([B],0)+isnull([C],0)+isnull([D],0) as TotalSessions 
FROM 
--... rest of the query
