Remove メソッド
プル サブスクリプションを削除します。
名前空間: Microsoft.SqlServer.Replication
アセンブリ: Microsoft.SqlServer.Rmo (Microsoft.SqlServer.Rmo.dll)
構文
'宣言
Public Sub Remove
'使用
Dim instance As PullSubscription
instance.Remove()
public void Remove()
public:
void Remove()
member Remove : unit -> unit
public function Remove()
説明
サブスクライバでサブスクリプションを削除したら、RemovePullSubscription または RemovePullSubscription を呼び出して、パブリッシャ側のサブスクリプションの登録を削除する必要があります。
Remove メソッドを呼び出すことができるのは、パブリッシャ側の固定サーバー ロール sysadmin のメンバ、またはサブスクリプション データベースの固定データベース ロール db_owner のメンバだけです。
Remove を呼び出すと、sp_droppullsubscription (Transact-SQL) または sp_dropmergepullsubscription (Transact-SQL) を実行したのと同じことになります。
この名前空間、クラス、またはメンバは、.NET Framework 2.0 でのみサポートされています。
