屬性值
指派給物件PipelineBuffer的IDTSOutput100整數 ID。
- 屬性
範例
以下程式碼範例利用 在緩衝區 FindColumnByLineageID中定位輸出欄位。 欄位的索引儲存在內部成員陣列中,因此可透過 PrimeOutput 方法或方法 ProcessInput 存取。
Private columnIndex As Integer()
Public Overrides Sub PreExecute()
Dim output As IDTSOutput100 = ComponentMetaData.OutputCollection(0)
columnIndex = New Integer(output.OutputColumnCollection.Count - 1) {}
Dim x As Integer = 0
While x < output.OutputColumnCollection.Count
Dim col As IDTSOutputColumn100 = output.OutputColumnCollection(x)
columnIndex(x) = BufferManager.FindColumnByLineageID(output.Buffer, col.LineageID)
x -= 1
End While
End Sub
int []columnIndex;
public override void PreExecute()
{
IDTSOutput100 output = ComponentMetaData.OutputCollection[0];
columnIndex = new int[output.OutputColumnCollection.Count];
for(int x=0; x< output.OutputColumnCollection.Count; x++)
{
IDTSOutputColumn100 col = output.OutputColumnCollection[x];
columnIndex[x] = BufferManager.FindColumnByLineageID( output.Buffer,col.LineageID);
}
}
備註
此執行時特性主要用作該屬性方法FindColumnByLineageID的參數,用BufferManager以定位欄位。PipelineBuffer
