jointure entre les tables

Bonjour

J'ai une jointure entre les tables employes et vacation one to many
Hibernate a généré les deux classes Employes et Vacation
Je voudrais calculer la durée des congés en une année pour chaque employés ! j'ai essayé d'utiliser les requêtes SQL classiques dans la couche service. Mais je ne sais pas comment faire?
Code:

1 2 3 4 5 public List<Double> findDuration() { return (List<Double>) hibernateTemplate .find("select duration from Vacation INNER Join Employes ON Vacation.employes.id=Employes.id where employes.id=?1 "); //DELETE salaire.* FROM Employés INNER JOIN Salaire ON Employés.NumEmployé = Salaire.NumEmployé }
SVP help me !:?

Bonjour,pour bien comprendre hibernate voila un référence qui s'appelle "hibernate in action" si vous comprenez l'anglais surement il vous aidera.

veuillez nous donner les attributs de employé et vacation.

SELECT sum( datediff( vtn.End_date, vtn.Start_date ) )
FROM vacation vtn
WHERE vtn.employes_ID =1
AND vtn.Start_date > "01-01-2010"
AND vtn.End_date < "31-12-2010"

J'ai fait le binding de Emplyes avec Vacation dans mon controlleur (j'utilise Spring MVC)
