BypassPrepare プロパティ
リレーショナル データベース管理システム (RDBMS) に SQL ステートメントを送信するときに、SQL 実行タスクがステートメントの準備をスキップするかどうかを示す Boolean を取得します。値の設定も可能です。
名前空間: Microsoft.SqlServer.Dts.Tasks.ExecuteSQLTask
アセンブリ: Microsoft.SqlServer.SQLTask (Microsoft.SqlServer.SQLTask.dll)
構文
'宣言
Public Property BypassPrepare As Boolean
Get
Set
'使用
Dim instance As ExecuteSQLTask
Dim value As Boolean
value = instance.BypassPrepare
instance.BypassPrepare = value
public bool BypassPrepare { get; set; }
public:
virtual property bool BypassPrepare {
bool get () sealed;
void set (bool value) sealed;
}
abstract BypassPrepare : bool with get, set
override BypassPrepare : bool with get, set
final function get BypassPrepare () : boolean
final function set BypassPrepare (value : boolean)
プロパティ値
型: System. . :: . .Boolean
タスクが SQL コマンドの準備をバイパスする場合は true、RDBMS が実行前にステートメントを準備する場合は false です。
実装
説明
このプロパティは、OLE DB 接続のために prepare コマンドをバイパスする機能を提供します。これは、prepare で restore のようないくつかの Transact-SQL キーワードがサポートされないためです。このプロパティを true に設定した場合、コマンドは準備されることなく実行されます。
使用例
次の例では、まず ExecuteSQLTask を作成し、次に TaskHost を使用して、BypassPrepare を含むプロパティの既定の設定を示します。その後、一部のプロパティの値を設定して、プロパティ値の設定方法を示します。
