BulkInsertTask.KeepIdentity Propriété

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

public bool KeepIdentity { get; set; }

member this.KeepIdentity : bool with get, set

Public Property KeepIdentity As Boolean

Valeur de propriété

true si la valeur ou les valeurs d’identité dans le fichier de données importé doivent être utilisées pour la colonne d’identité. true affecte les valeurs spécifiées dans le fichier source à la colonne d’identité ; false ignore les valeurs de colonne d’identité spécifiées dans la source. La valeur par défaut est true.

Exemples

L’exemple suivant crée un BulkInsertTask, puis affiche les paramètres par défaut des propriétés, y compris le KeepIdentity, à l’aide du TaskHost. L’exemple définit ensuite deux champs pour montrer comment définir des valeurs de champ.
