들여다보기,여러 IQueryables를 함께 병합 - Silverlight
Im 다시 태어난 실버 버스트이므로 나와 함께하시기 바랍니다. 두 개의 서로 다른 SQL 데이터베이스 서버를 가리키는 두 개의 별도 DomainServices가 있습니다. 이러한 도메인 서비스 내에서 각 도메인 서비스에 IQueryables를 설치했습니다.
별도의 DomainServices에서 두 개의 IQueryables를 병합해야합니다. 이게 할 수 있어야한다고 확신 해요.
다음은 두 도메인 서비스입니다.
GetCustomCallLogs (HEATLiveDomainService)와 GetTblCallsLogged (HeatDomainService)를 병합하고 싶습니다. GetCustomCallLogs의 키는 CallID이고 GetTblCallsLogged의 키는 RecID입니다.
가능한 경우 계정에 두 개의 조인 된 테이블의 모든 필드를 가져올 새 형식을 만들어야한다는 것을 이해해야합니다.
내 시나리오에 대해 설명해 주셨으면합니다. 사전에
감사

주의 사항 : 가 너무 밖으로 질문 소스 (SQL 서버)에서 그 일을, 서버에 연결 할 수 없습니다. SP를 만들고 OpenQuery를 사용할 수 없습니다. (정확히 할 수는 있지만 올바른 방법을 배우고 싶습니다.) 올바른 방법은 아닙니다.
