ReplicationObject.CachePropertyChanges 속성

정의

네임스페이스:

Microsoft.SqlServer.Replication

어셈블리:

Microsoft.SqlServer.Rmo.dll

복제 속성에 대한 변경 내용을 캐시할지 아니면 즉시 적용할지를 가져오거나 설정합니다.

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

public bool CachePropertyChanges { get; set; }

member this.CachePropertyChanges : bool with get, set

Public Property CachePropertyChanges As Boolean

속성 값

Boolean

Boolean 값입니다. true이면 속성 변경이 캐시됩니다. false이면 속성 변경이 즉시 적용됩니다.

설명

값이면 개체의 CachePropertyChanges 속성에 따라 속성 ServerConnection 변경 내용이 SqlExecutionModes 즉시 설정false됩니다. 값이 설정 true되면 속성 변경 내용이 호출될 때까지 CommitPropertyChanges 캐시됩니다. CommitPropertyChanges 호출되면 속성에 따라 모든 CachePropertyChanges 속성 변경 내용이 SqlExecutionModes 설정됩니다.

캐싱은 Microsoft SQL Server 저장된 속성에만 적용됩니다.

CachePropertyChanges 의 기본값은 false입니다.
