Parameter

  • Changed
    Typ: System. . :: . .Boolean%
    [out] Ein Boolean-Wert, der angibt, ob das an die Methode übergebene Dataset sich von dem Dataset unterscheidet, das von der Methode zurückgegeben wurde. Verwenden Sie diese Eigenschaft, um zu bestimmen, ob sich das Eingabedataset vom Ausgabedataset unterscheidet.
  • ParameterNames
    Typ: array<System. . :: . .String> [] () [] []%
    [out] Die Namen der Abfrageparameter, die in der zugrunde liegenden semantischen Abfrage verwendet werden. Dieser Ausgabeparameter wird nur verwendet, wenn die DataSource auf ein Modell verweist.

Rückgabewert

Typ: ReportService2005. . :: . .DataSetDefinition
Ein DataSetDefinition-Objekt mit den Feldern und der Übermittlungsabfrage, die aus der angegebenen Datenquelle abgerufen werden.

Required Permissions

Depends on the item type:

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 Übersicht über Datenverarbeitungserweiterungen.
