Hi, i have this table libro_prestito that contains: id_libro|id_autore --------+--------- s1 | 5 n3 | 1 s2 | 2 k1 | 1 n2 | 2 n2 | 3 n2 | 4 n1 | 1 n1 | 4 now i must to update the id_libro column, but with this update I can have the necessity to delete or insert some new element. My question is : is better to delete the old reference and then insert the new or what ? Ok, my english is very very bad. A little example: I must to change id_libro = 'n2' in 'n3' and change/update old item and (ok, this the maximum case, but i need one code for all) delete the item "n2 | 4" and add the item "n2 | 5".
