SpecialFields
This collection contains SpecialField objects that represent special fields in a table of external database. To access objects in the collection, use the Item method. Access to collection items is possible both by name and by internal number. The collection provides continuity of field internal numbers. Persistence of internal number is guaranteed within a session of external database. Adding special fields to and removing special fields from the collection is not possible. If an ODBC data source does provide information about special fields in a table, the collection will be empty. The collection is always empty for GDB tables.
