Hi, i have to make an update to the table "libro_autore". A table where
there are 2 items: id_libro -- id_autore. The corrispondence is n:n .
There is a problem, in this update I can have to change only the id_libro
(simple), but I can have to:
-insert some new "id_autore"
-delete some "id_autore"
-insert and delete some "id_autore".
In this case it is better to delete from table all id_libro-id_autore and
then reinsert the "ok" item or what ?
