パラメータ

• subscriber
  プル サブスクリプションが作成されたサブスクライバの名前を指定する String 値です。

• subscriptionDB
  サブスクリプション データベースの名前を指定する String 値です。

• syncType
  サブスクリプションの同期方法を指定する SubscriptionSyncType オブジェクトの値です。

• subscriberType
  サブスクライバがアーティクル イメージのデータの変更を開始するときのサブスクリプションの動作を指定する TransSubscriberType オブジェクトの値です。

解説

プル サブスクリプションを作成するときにパブリッシャ側で MakePullSubscriptionWellKnown を呼び出す必要があります。

パブリッシャ側でサブスクリプションが既に登録されているかどうかを確認するには、EnumSubscriptions を使用します。登録されている場合は、MakePullSubscriptionWellKnown によってサーバーでエラーが生成されます。

MakePullSubscriptionWellKnown 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、パブリケーション データベースの固定データベース ロール db_owner のメンバ、またはパブリケーション アクセス リスト (PAL) のユーザーだけです。

MakePullSubscriptionWellKnown を呼び出すと、プル サブスクリプションで sp_addsubscription 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。
