-----Message d'origine----- De : Thomas Dudziak [mailto:[EMAIL PROTECTED] Envoyé : mercredi 9 février 2005 13:52 À : OJB Users List Objet : Re: [newbie] ODMG API : updating an object's primary key. But as far as OJB and the database is concerned, it is a new one, because they cannot determine to which 'old' one it corresponds. The problem here is that OJB and the database use object equality (if two objects are equal as determined by equals()/hashCode()) whereas you want to use identity (same java object as determined by ==, i.e. location in memory). So you either got to delete the old object/row and then insert the new one, or introduce a separate primary key.
