DatabaseName プロパティ

サブスクリプションデータベースの名前を取得します。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 DatabaseName As String
    Get
    Set
'使用
Dim instance As PullSubscription
Dim value As String

value = instance.DatabaseName

instance.DatabaseName = value

public string DatabaseName { get; set; }

public:
property String^ DatabaseName {
    String^ get ();
    void set (String^ value);
}

member DatabaseName : string with get, set

function get DatabaseName () : String
function set DatabaseName (value : String)

プロパティ値

型: System. . :: . .String
String 値です。

説明

DatabaseName は必須プロパティであり、サーバーでサブスクリプションを作成する前に設定する必要があります。サブスクリプションがサーバー上に存在するようになった後は、DatabaseName プロパティを変更することはできません。

DatabaseName プロパティを取得できるのは、サブスクライバ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。

DatabaseName プロパティを設定できるのは、サブスクライバ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。

DatabaseName プロパティを取得すると、sp_helppullsubscription (Transact-SQL) または sp_helpmergepullsubscription (Transact-SQL) を実行したのと同じことになります。

DatabaseName プロパティを設定すると、sp_addpullsubscription (Transact-SQL) または sp_addmergepullsubscription (Transact-SQL) を実行したのと同じことになります。

DatabaseName プロパティは、SQL Server 7.0、SQL Server 2000、および SQL Server 2005 で使用できます。

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。
