Hi, I have this table : prestito where there is the column "id_libro" that contains all the book that are not in my house (with some other infos). But I have the table "libro" that contains the data about every books in my house. Now I have a query /via web interface with php) that give me infos about all books and if the book is in the house I put an button in the page (via php script). Now, for this choice (button or not button) it is better a column call "id_utente" in the "libro" table or a select from the "prestito" table foreach book ? exscume me for my bad english "Il divertimento e' giusto se la scimmia ci prende gusto" -- Italian Linux Press: http://ziobudda.enter.it/ILP/ -- Morelli 'ZioBudda' Davide Michel - Member of Pluto Linux User Group [EMAIL PROTECTED] - http://ziobudda.enter.it/ Linux Problem?
