JScript does not support passing value-type arguments by reference.

Parameters

DataSource
The data source for the delivery query.

DataSet
The dataset containing the delivery query and fields for a data-driven subscription.

Changed
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
A parameters element that provides information about parameters in the query. This argument is only used when the DataSource references a model.

Return Value

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

Remarks

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 Introducing Data Processing Extensions.
