동일한 열에서 여러 합계

Question

다른 where 절을 기반으로 동일한 열의 합계를 반환하려면이 select 쿼리가 필요합니다. 기본적으로 이러한 여러 선택 쿼리를 병합하는 방법을 찾고 있습니다. 아래를 봐주세요. 어떤 도움이라도 대단히 감사합니다!

DECLARE @prEndDate smalldatetime 
SET @prEndDate='2014-01-05' 

SELECT Employee, SUM(Amount) as Deduction 
FROM bPRDT 
WHERE PREndDate=@prEndDate 
AND EDLCode=100 AND EDLType='D' 
GROUP BY Employee 

SELECT Employee, SUM(Amount) as DeductionPlus 
FROM bPRDT 
WHERE PREndDate=@prEndDate 
AND EDLCode=101 AND EDLType='D' 
GROUP BY Employee 

SELECT Employee, SUM(Amount) as Match 
FROM bPRDT 
WHERE PREndDate=@prEndDate 
AND EDLCode=600 AND EDLType='L' 
GROUP BY Employee 

SELECT Employee, SUM(Amount) as MatchPlus 
FROM bPRDT 
WHERE PREndDate=@prEndDate 
AND EDLCode=601 AND EDLType='L' 
GROUP BY Employee 

마지막으로 수정되었습니다. 당신은 UNION 또는 CASE WHEN 절을 사용할 수

DECLARE @prEndDate smalldatetime 
SET @prEndDate ='2013-12-29' 
SELECT 
REPLACE(c.SSN,'-',''), 
SUM(CASE WHEN a.EDLType='D' AND a.Amount > 0 AND (a.EDLCode=100 OR a.EDLCode=101) THEN a.Amount ELSE 0 END) AS Deferral, 
SUM(CASE WHEN a.EDLType='L' AND a.Amount > 0 AND (a.EDLCode=600 OR a.EDLCode=601) THEN a.Amount ELSE 0 END) AS EmployerMatch, 
SUM(CASE WHEN a.EDLType='D' AND a.Amount > 0 AND (a.EDLCode=100 OR a.EDLCode=101) THEN a.SubjectAmt ELSE 0 END) AS Compensation415, 
SUM(CASE WHEN a.EDLType='D' AND a.Amount > 0 AND (a.EDLCode=100 OR a.EDLCode=101) THEN a.SubjectAmt ELSE 0 END) AS PlanFullYearCompensation, 
SUM(CASE WHEN a.EDLType='E' AND a.Amount > 0 AND (a.EDLCode=1 OR a.EDLCode=2 OR a.EDLCode=3) THEN a.Hours ELSE 0 END) AS PlanHours 
FROM bPRDT a 
JOIN (SELECT DISTINCT SSN, Employee FROM bPREH) c ON a.Employee=c.Employee  
WHERE a.PREndDate=@prEndDate 

GROUP BY c.SSN 
ORDER BY Deferral DESC, c.SSN ASC 

Answer 1

: 여기 존재를 결국거야.

SELECT 
     Employee, 
     SUM(CASE WHEN EDLCode=100 AND EDLType='D' THEN Amount ELSE 0 END) as Deduction, 
     SUM(CASE WHEN EDLCode=101 AND EDLType='D' THEN Amount ELSE 0 END) as DeductionPlus 
     SUM(CASE WHEN EDLCode=600 AND EDLType='L' THEN Amount ELSE 0 END) as Match 
     SUM(CASE WHEN EDLCode=601 AND EDLType='L' THEN Amount ELSE 0 END) as MatchPlus 
FROM bPRDT 
WHERE PREndDate=@prEndDate 
GROUP BY Employee 

Answer 2

당신은 CASE 문에 WHERE 절에서하고있는 상태를 이동할 수 있습니다, 그래서 당신은 관심 행을 요약하면 : 직원, EDLCode, 대신 EDLType에 의해

DECLARE @prEndDate smalldatetime 
SET @prEndDate='2014-01-05' 

SELECT Employee, 
     SUM(CASE WHEN EDLCode=100 AND EDLType='D' THEN amount ELSE 0 END) 
      AS Deduction, 
     SUM(CASE WHEN EDLCode=101 AND EDLType='D' THEN amount ELSE 0 END) 
      AS DeductionPlus, 
     SUM(CASE WHEN EDLCode=600 AND EDLType='L' THEN amount ELSE 0 END) 
      AS Match, 
     SUM(CASE WHEN EDLCode=601 AND EDLType='L' THEN amount ELSE 0 END) 
      AS MatchPlus 
FROM  bPRDT 
WHERE PREndDate = @prEndDate 
GROUP BY Employee

그룹 그냥 직원.
