Answer 1

도움이 될 것인가?

SELECT c.new_name, d.new_SegmentName, ISNULL(COUNT(a.CustomerId),0) as jumlah 
    FROM filterednew_area c LEFT JOIN filteredaccount b ON b.new_AreaId = c.new_areaId 
    LEFT JOIN filterednew_partnersegment d ON b.new_PartnerSegmentId = d.new_partnersegmentId 
    LEFT JOIN filteredIncident a ON a.CustomerId = b.AccountId 
    WHERE MONTH(a.new_trxdate) = '10' AND YEAR(a.new_trxdate) = '2012' 
    AND c.new_areaid IN ('3C26906E-5C13-E211-8D39-005056850007','4E26906E-5C13-E211-8D39-005056850007') 
    GROUP BY c.new_name, d.new_SegmentName 

항상 영역을 원할 경우 참여를 시작해야합니다.

편집 : 편집 후 테이블 솔루션

select C.Area_Name, C.Segment_Name, ISNULL(count(I.incident_id), 0) 
from customer C left outer join incident I 
on C.Customer_name = I.Customer_Name 
group by C.Area_Name, C.Segment_Name

이 작업을 수행하려면 카티 제품에 해결책 나는 가능한 세그먼트와 테이블 세그먼트이 상상 (그리고 난 이 종류의 테이블이 첫 번째 쿼리에 있다고 생각하십시오.)

SELECT A.Area_Name, A.Segment_name, Count(Incident.Incident_Id) AS TOT 
FROM 
(
(SELECT Distinct Customer.Area_Name, Segment.Segment_name 
FROM Segment, Customer 
) AS A 
LEFT OUTER JOIN Customer AS C 
ON (C.Area_Name = A.Area_Name) AND (C.Segment_name = A.Segment_name) 
) 
LEFT OUTER JOIN Incident ON C.Customer_Name = Incident.Customer_name 
GROUP BY A.Area_Name, A.Segment_name; 

쿼리의 결과

Area_Name | Segment_name | TOT 

JAKARTA | AIRPORT  | 0 
JAKARTA | PETROLEUM | 1 
JAKARTA | TRADITIONAL | 1 
MEDAN  | AIRPORT  | 1 
MEDAN  | PETROLEUM | 0
