j'avais trouvé ca :
("SELECT * FROM objectif
WHERE num_parametre = (SELECT * FROM parametre
WHERE num_equipement =(SELECT * FROM equipement
WHERE num_D_P = (SELECT * FROM Lien_D_P
WHERE num_processus = (SELECT * FROM processus
WHERE num_processus = '$var' ))));")
Est-ce bon ?? car je ne peux pas encore tester .
