<Fuente>.MigrateLinkedCompositeKey (Función)
 Disponible solo con este tipo de conexión
Migrates the values of the linked composite keys coming from a file in Hyper File 5.5 format to the 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 the linked keys corresponding to a composite key is incorrect once the files have been migrated from Hyper File 5.5 to HFSQL Classic. <Fuente>.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: - with files in HFSQL Classic format (files in 5.5 format migrated to the 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 <Fuente>.MigrateLinkedCompositeKey, the values of the new records may be corrupted.
