Requete Delete avec PreparedStatement
Mon petit probleme concerne l'envoie d'une requete delete a l'aide de l'objet PreparedStatement ( en cliquant sur le Jbutton approprié une exception sort son ptit nez java.sql.SQLException: La position de colonne '1' est en dehors des limites. Le nombre de colonnes de ce ResultSet est '0'.) , je pense avoir suivi la bonne procedure pour l'envoie de la requete PreparedStatement puisqu'elle marche tres bien pour l'ajout.
L'exception apparaît à la ligne : state2.setString(1, personne.getNom());
