Thank You Massimo on your quick responce. Actually, I don't need an id value. I need some kind of unique, autoincremented integer. I though I could copy an id value but..., you provided enough resons that this cannot be done.
Actually, fields 'jmbg' and 'jib' are xor combination, so to call it. (If one is present, other is not), so if 'jib' is entered, 'jmbg' should not be. In the same time both should be unique and thus could not left empty. I thought some kind of incremented integer would do the job.
