Attributes プロパティ

パブリケーション属性を取得します。値の設定も可能です。

名前空間:  Microsoft.SqlServer.Replication
アセンブリ:  Microsoft.SqlServer.Rmo (Microsoft.SqlServer.Rmo.dll)

構文

'宣言
Public Property Attributes As PublicationAttributes
    Get
    Set
'使用
Dim instance As Publication
Dim value As PublicationAttributes

value = instance.Attributes

instance.Attributes = value
public PublicationAttributes Attributes { get; set; }
public:
property PublicationAttributes Attributes {
    PublicationAttributes get ();
    void set (PublicationAttributes value);
}
member Attributes : PublicationAttributes with get, set
function get Attributes () : PublicationAttributes
function set Attributes (value : PublicationAttributes)

説明

PublicationAttributes 列挙は、列挙値のビット演算の組み合わせを許可する FlagsAttribute オプションをサポートします。トランザクション パブリケーションまたはスナップショット パブリケーションの既定の属性値、およびマージ パブリケーションの既定の属性値の詳細については、それぞれ、「sp_addpublication (Transact-SQL)」および「sp_addmergepublication (Transact-SQL)」を参照してください。

Attributes プロパティを取得できるのは、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。

Attributes プロパティを設定できるのは、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 のメンバだけです。既存のパブリケーションの Attributes プロパティは、PAL のユーザーが設定できます。

Attributes プロパティを取得すると、sp_helppublication または sp_helpmergepublication を実行したのと同じことになります。

Attributes プロパティを設定すると、sp_addpublicationsp_changepublication または sp_addmergepublicationsp_changemergepublication 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。
