<Source>.MigrateLinkedCompositeKey (Función)
 Disponible solo con este tipo de conexión
Migrates linked compound key values from a data file in Hyper File 5.5 format to HFSQL Classic format. | | When should I use this function? The format of composite keys changed between Hyper File 5.5 and HFSQL Classic (single-user or multi-user). Consequence: the value of linked keys corresponding to a compound key is no longer correct after migration of data files from Hyper File 5.5 format to HFSQL Classic format. <Source>.MigrateLinkedCompositeKey changes the value of the linked keys and retrieves the value of the composite key in the linked key. Use conditions This function must be used: - only with data files in HFSQL Classic format (data files in 5.5 format migrated to Classic format),
- once for each key to migrate,
- just after the migration from Hyper File 5.5 to HFSQL Classic. If records are added between the migration and the call to <Source>.MigrateLinkedCompositeKey, the values of the new records may be corrupted.
