構文

'宣言
Public Property Type As ArticleOptions

public ArticleOptions Type { get; set; }

public:
property ArticleOptions Type {
    ArticleOptions get ();
    void set (ArticleOptions value);
}

/** @property */
public ArticleOptions get_Type ()

/** @property */
public void set_Type (ArticleOptions value)

public function get Type () : ArticleOptions

public function set Type (value : ArticleOptions)

プロパティ値

アーティクルの種類を指定する ArticleOptions 列挙値です。

例外

例外の種類	条件
ApplicationException	Type にサポートされていない ArticleOptions 値を設定したり、既存のアーティクルに Type を設定したりすると発生します。

解説

Type プロパティの既定値は、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場合 LogBased、マージ パブリケーションの場合 TableBased です。

Create を呼び出してサーバー上にアーティクルを作成する前に、Type プロパティを設定する必要があります。アーティクルがサーバー上に存在するようになった後は、このプロパティを設定できません。

Type プロパティを取得できるのは、パブリッシャ側およびサブスクライバ側 (サブスクライバを再パブリッシュする場合) の固定サーバー ロール sysadmin のメンバです。また、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、および PAL のメンバも取得できます。MergeArticle オブジェクトの場合は、ディストリビュータ側の固定データベース ロール replmonitor のメンバも取得できます。

Type 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 のメンバです。また、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 のメンバも設定できます。

Type を取得すると、sp_helparticle (Transact-SQL) (トランザクション レプリケーションまたはスナップショット レプリケーションの場合) または sp_helpmergearticle (Transact-SQL) (マージ レプリケーションの場合) を実行したのと同じことになります。

Type を設定すると、sp_addarticle (Transact-SQL) (トランザクション レプリケーションまたはスナップショット レプリケーションの場合) または sp_addmergearticle (Transact-SQL) (マージ レプリケーションの場合) を実行したのと同じことになります。

Type プロパティは、SQL Server 2005、SQL Server 2000、および SQL Server 7.0 で利用できます。

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。
