ReplicationObject.CachePropertyChanges プロパティ

レプリケーション プロパティに加えられた変更をキャッシュするか、またはすぐに適用するかを取得します。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 CachePropertyChanges As Boolean 
    Get 
    Set
'使用
Dim instance As ReplicationObject 
Dim value As Boolean 

value = instance.CachePropertyChanges

instance.CachePropertyChanges = value

public bool CachePropertyChanges { get; set; }

public:
property bool CachePropertyChanges {
    bool get ();
    void set (bool value);
}

member CachePropertyChanges : bool with get, set

function get CachePropertyChanges () : boolean 
function set CachePropertyChanges (value : boolean)

プロパティ値

型: System.Boolean
Boolean 値です。true の場合、プロパティの変更はキャッシュされます。false の場合、プロパティの変更はすぐに適用されます。

説明

CachePropertyChanges の値が false の場合、プロパティの変更は、ServerConnection オブジェクトの SqlExecutionModes プロパティに従って、すぐに設定されます。 値を true に設定すると、プロパティの変更は、CommitPropertyChanges が呼び出されるまでキャッシュされます。 CommitPropertyChanges が呼び出されると、CachePropertyChanges の後で加えられたすべてのプロパティ変更が、SqlExecutionModes プロパティに従って設定されます。

キャッシュは、Microsoft SQL Server に格納されたプロパティにのみ適用されます。

CachePropertyChanges の既定値は false です。
