필드의 이중 계산없이 동일한 쿼리에서 결합 및 계산

Question

특정 조건에서 일부 테이블에 합류했습니다. 조인에서 제외 된 레코드의 수를 표시 할 수 있는지 알고 싶습니다.

내 질문 : 당신이 볼 수있는

SELECT... 

FROM   dbo.QuickLabDump 
      ... 

      left outer join hermes.lom.dbo.lom_specimen Lom 
       on QuickLabDump.[specimen id] = lom.specimen 
       LEFT outer join SalesDWH.dbo.Isomers Isomers 
       on QuickLabDump.[specimen id] = Isomers.[accession id] 



WHERE  lom.specimen is null 
       and isomers.[accession id] is null... 

난이 개 왼쪽 외부 조인 있습니다.

이 쿼리의 결과 외에 나는 또한 제외 된 hermes.lom.dbo.lom_specimen 및 SalesDWH.dbo.Isomers에서 해당 레코드의 수를 반환하고자합니다.

제외 된 필드의 수는 어떻게 계산합니까?

Answer 2

WHERE 절없이 동일한 쿼리를 실행하고 FULL OUTER JOIN을 사용하면 선택 가능한 유니버스의 모든 행을 얻을 수 있습니다.
