BulkInsertTask.TableLock Proprietà

Definizione

Ottiene o imposta un valore booleano che indica se la tabella è bloccata durante l'operazione di inserimento bulk.

public:
 property bool TableLock { bool get(); void set(bool value); };
public bool TableLock { get; set; }
member this.TableLock : bool with get, set
Public Property TableLock As Boolean

Valore della proprietà

true se si desidera bloccare la tabella durante l'inserimento bulk; false se non si vuole bloccarlo.

Esempio

L'esempio seguente crea un BulkInsertTaskoggetto e quindi mostra le impostazioni predefinite delle proprietà, incluso , TableLockusando .TaskHost Nell'esempio vengono quindi impostati due campi per illustrare come impostare i valori dei campi.
