방법: 끌어오기 구독 삭제(RMO 프로그래밍)
RMO(복제 관리 개체)를 사용하여 프로그래밍 방식으로 끌어오기 구독을 삭제할 수 있습니다. 끌어오기 구독을 삭제하는 데 사용되는 RMO 클래스는 끌어오기 구독이 구독하는 게시의 유형에 따라 다릅니다.
스냅숏 또는 트랜잭션 게시에 대한 끌어오기 구독을 삭제하려면
ServerConnection 클래스를 사용하여 구독자 및 게시자 모두에 대한 연결을 만듭니다.
TransPullSubscription 클래스의 인스턴스를 만들고 PublicationName, DatabaseName, PublisherName 및 PublicationDBName 속성을 설정합니다. 1단계의 구독자 연결을 사용하여 ConnectionContext 속성을 설정합니다.
IsExistingObject 속성을 확인하여 구독이 존재하는지 확인합니다. 이 속성의 값이 false이면 2단계에서 구독 속성이 올바르게 정의되지 않았거나 구독이 없는 것입니다.
Remove 메서드를 호출합니다.
1단계에서 만든 게시자 연결을 사용하여 TransPublication 클래스의 인스턴스를 만듭니다. Name, DatabaseName 및 ConnectionContext를 지정합니다.
LoadProperties 메서드를 호출합니다. 이 메서드가 false를 반환하는 경우 5단계에서 지정한 속성이 올바르지 않거나 서버에 게시가 없는 것입니다.
RemovePullSubscription 메서드를 호출합니다. subscriber 및 subscriberDB 매개 변수에 구독자의 이름과 구독 데이터베이스를 지정합니다.
병합 게시에 대한 끌어오기 구독을 삭제하려면
ServerConnection 클래스를 사용하여 구독자 및 게시자 모두에 대한 연결을 만듭니다.
MergePullSubscription 클래스의 인스턴스를 만들고 PublicationName, DatabaseName, PublisherName 및 PublicationDBName 속성을 설정합니다. 1단계의 연결을 사용하여 ConnectionContext 속성을 설정합니다.
IsExistingObject 속성을 확인하여 구독이 존재하는지 확인합니다. 이 속성의 값이 false이면 2단계에서 구독 속성이 올바르게 정의되지 않았거나 구독이 없는 것입니다.
Remove 메서드를 호출합니다.
1단계에서 만든 게시자 연결을 사용하여 MergePublication 클래스의 인스턴스를 만듭니다. Name, DatabaseName 및 ConnectionContext를 지정합니다.
LoadProperties 메서드를 호출합니다. 이 메서드가 false를 반환하는 경우 5단계에서 지정한 속성이 올바르지 않거나 서버에 게시가 없는 것입니다.
RemovePullSubscription 메서드를 호출합니다. subscriber 및 subscriberDB 매개 변수에 구독자의 이름과 구독 데이터베이스를 지정합니다.
