Замечания

The IDTSExternalMetadataColumn100 column represents a column in a remote data source. It contains the same properties as the external data column. This allows components to validate the columns in their IDTSInput100 and IDTSOutput100 column collections when the external data source itself is unavailable, or when a round trip to the external source is undesirable.
