Paramètres

  • Changed
    Type : System. . :: . .Boolean%
    [out] A Boolean value that indicates whether the dataset that was passed to the method is different from the one returned by the method. Use this property to determine whether the input dataset is different from the output dataset.
  • ParameterNames
    Type : array<System. . :: . .String> [] () [] []%
    [out] The names of the query parameters used in the underlying semantic query. This out parameter is only used when the DataSource references a model.

Valeur de retour

Type : ReportService2005. . :: . .DataSetDefinition
A DataSetDefinition object that contains the fields and the delivery query that are retrieved from the given data source.

Notes

Pass the DataSetDefinition object that is returned by the PrepareQuery method as input to the CreateDataDrivenSubscription and SetDataDrivenSubscriptionProperties methods.

The delivery query returns a set of fields that can be mapped to report parameter values and delivery extension settings for data-driven subscriptions. Each row in the result set contains values for a single recipient, such as an e-mail address to which the report is delivered.

The delivery query must be valid for one of the data processing extensions that are installed on the report server. For more information, see Vue d'ensemble des extensions pour le traitement des données.
