iOutputColumnID
The ID of the IDTSOutputColumn90 object.

iExternalMetadataColumnID
The ID of the IDTSExternalMetadataColumn90 object.

bMatch

Valor devuelto

The IDTSExternalMetadataColumn90 that is mapped to the output column.

Notas

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.
