Параметры

    Indicates whether the output column and external metadata columns match.

Возвращаемое значение

The IDTSExternalMetadataColumn90 that is mapped to the output column.

Замечания

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 Implementing External Metadata.
