public function MapOutputColumn (
iOutputID : int,
iOutputColumnID : int,
iExternalMetadataColumnID : int,
bMatch : boolean
) : IDTSExternalMetadataColumn100
Parameters
- iOutputID
The ID of the IDTSOutput100 object.
- iOutputColumnID
The ID of the IDTSOutputColumn100 object.
- iExternalMetadataColumnID
The ID of the IDTSExternalMetadataColumn100 object.
- bMatch
Indicates whether the columns match.
Return Value
The IDTSExternalMetadataColumn100 that is mapped to the output column.
Remarks
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 that you want to allow the mapping to occur.
For more information about working with external metadata columns, see Implementing External Metadata.
