주의
Data flow components call this method when they have finished adding rows to an Output PipelineBuffer. Calling SetEndOfRowset notifies the data flow engine that a component has finished adding rows to the PipelineBuffer. The SetEndOfRowset method then sets the value of the EndOfRowset property to true on the final buffer.
The PipelineBuffer produces a NotOutputBufferException when the Mode of the PipelineBuffer is Input and this method is called.
예
The following example shows a source component that calls SetEndOfRowset to signal that it is finished adding rows to the PipelineBuffer.
using System;

using Microsoft.SqlServer.Dts.Pipeline.Wrapper;
using Microsoft.SqlServer.Dts.Runtime.Wrapper;

public class SampleSourceComponent: PipelineComponent
{
public override void ProvideComponentProperties()
{
IDTSOutput100 output = ComponentMetaData.OutputCollection.New();
output.Name = "SourceOutput";
IDTSOutputColumn100 column = output.OutputColumnCollection.New();
column.Name = "Column1";
column.SetDataTypeProperties(DataType.DT_R8, 0, 0, 0, 0);
}
public override void PrimeOutput(int outputs, int[] outputIDs, PipelineBuffer[] buffers)
{
double d = 123.5;
buffers[0].AddRow();
buffers[0].SetDouble(0, d);
buffers[0].SetEndOfRowset();
}
}
