Remove メソッド

現在接続されているディストリビュータからこのパブリッシャの登録を削除します。

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 ( _
    force As Boolean _
)
'使用
Dim instance As DistributionPublisher
Dim force As Boolean

instance.Remove(force)
public void Remove(
    bool force
)
public:
void Remove(
    bool force
)
member Remove : 
        force:bool -> unit 
public function Remove(
    force : boolean
)

パラメーター

  • force
    型: System. . :: . .Boolean
    パブリッシャが別のサーバーにある場合に、パブリッシャからもディストリビュータをアンインストールしていることを確認せずに、ディストリビュータからパブリッシャをアンインストールするかどうかを指定する Boolean 値です。true の場合、到達できないリモート サーバー上にパブリッシャがあっても、パブリッシャに関連付けられたすべてのレプリケーション オブジェクトは削除されます。false の場合、レプリケーションは、最初にリモート パブリッシャによってディストリビュータがアンインストールされていることを確認します。

説明

force が true に設定されていると、リモート パブリッシャに残っているパブリッシング メタデータをすべてクリーンアップすることが必要になる場合があります。

パブリッシャがディストリビュータと同じサーバー上にある場合、レプリケーションでは、ローカル サーバーにパブリケーションまたはディストリビューション オブジェクトが残っていないことが確認されます。

Remove メソッドを呼び出すことができるのは、ディストリビュータ側の固定サーバー ロール sysadmin のメンバだけです。

Remove を呼び出すと、ディストリビュータ側で sp_dropdistpublisher 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。
