Параметры

  • outputs
    Тип: System.Int32
    The number of elements in the outputIDs and buffers arrays.

Замечания

The number of elements in the outputIDs and buffers array is determined by the number of IDTSOutput100 objects in the IDTSOutputCollection100 collection of the component connected to an IDTSPath100 object.

Each element in the outputIDs array has a PipelineBuffer at the same index in the buffers array.

Rows are added to the PipelineBuffer by calling the AddRow method, and when finished, the SetEndOfRowset method is called to notify the data flow task that the component is finished adding rows. The SetEndOfRowset method sets the value of the EndOfRowset property to true on the final buffer.

PrimeOutput is called for components whose SynchronousInputID property is set to zero.
