Bonjour,
j'ai un probleme pour faire une restriction avec criteria et même avec HQL je n'arrive pas.

J'ai une table Action(#ActionId, ActionDate, ActionGroupe), lié a une classe entité ActionVO (AcnId, AdnDate, AcnGroupe)

Je souhaite recupérer les dernieres actions de chaque groupe.
En sql ca donnerait quelque chose comme

SELECT A.* from Action A
JOIN (select ActionGroupe, max(ActionDate) as dt_action from Action group by ActionGroupe) B
ON A.ActionGroupe = B.ActionGroupe AND A.ActionDate = B.dt_action;

MERCI D'AVANCE POUR VOTRE AIDE.
