1:N 엔터티 관계 만들기

다음 샘플에서는 EligibleCreateOneToManyRelationship 메서드를 사용하여 Account 및 Campaign 엔터티가 1:N 엔터티 관계에 참여할 수 있는지 확인한 후 CreateOneToManyRequest를 사용하여 엔터티 관계를 만듭니다.

N:N 엔터티 관계 만들기

엔터티 관계 검색

다음 샘플에서는 RetrieveRelationshipRequest를 사용하여 앞에서 만든 두 엔터티 관계를 검색합니다. 첫 번째 예제는 MetadataId를 사용하고 두 번째 예제는 Name을 사용합니다.

RetrieveRelationshipRequest retrieveOneToManyRequest =
    new RetrieveRelationshipRequest { MetadataId = _oneToManyRelationshipId };
