An incremental update can be carried out using the following procedure:
- Select records from the previous release of Suburbs and Localities data where the SL_UFI values match those of the Changelog and the Change type = D or U (Deletion or Update respectively).
- Delete the selected records from the old Suburbs and Localities data.
- Select from the new Suburbs and Localities data where the SL_UFI values match those of the changelog and the change type = I or U (Insertion or Update respectively).
- Append the selected records to the old Suburbs and Localities data. The resulting table will be equivalent to the supplied table of the new version.
