參數
- lOutputID
型別：System.Int32
The ID of the IDTSOutput100 object.
- lOutputColumnID
型別：System.Int32
The ID of the IDTSOutputColumn100 object.
- lExternalMetadataColumnID
型別：System.Int32
The ID of the IDTSExternalMetadataColumn100 object that is linked to the output column.
- bMatch
型別：System.Boolean
Indicates whether the output column and external metadata columns match.
傳回值
型別：Microsoft.SqlServer.Dts.Pipeline.Wrapper.IDTSExternalMetadataColumn100
The IDTSExternalMetadataColumn100 that is mapped to the output column.
備註
This method is called to map an output column to a column in the ExternalMetadataColumnCollection of the output. When you are developing a custom data flow component, you override this method, to ensure that the external columns and the output column match, and to indicate that you want to allow the mapping to occur. For more information about working with external metadata columns, see 實作外部中繼資料.
