J'ai une application ou j'ai eu à mapper une Heritage.j'ai la classe mere

@Entity
@Inheritance(strategy= InheritanceType.SINGLE_TABLE)
@Table(name = "agent")
@DiscriminatorColumn(name="TYPE_AGENT")
@DiscriminatorValue("AGENT")
public class Agent implements Serializable {}

Une classe fille

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
5
6
@Entity
@DiscriminatorValue("chefcellule")
 
public class Chefcellule extends Agent implements Serializable {
 
}

et

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
5
@Entity
@DiscriminatorValue("gestionnaire")
public class Gestionnaire extends Agent implements Serializable {
 
}

Je voudrais pouvoir modifier une entité ChefCellulle en Gestionnaire.Pour jongler car je ne sais pas j'ai eu à utiliser une mise à jour SQL

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

  String jpql = "update agent set TYPE_AGENT = :groupe  WHERE login = :login";

Il fait des MAJ dans la BD.mais à l'appel de la méthode retournant tous les agents genre

agentDao.findAll()

j'ai cette erreur.Je sais que ce n'est pas cool mais il me faut mettre à jour c'est une contrainte qui m'a été soumise voici la stracktrace

Merci pour votre aide si cela est possible.

C'etait un problème de casse lors du remplacement de :groupe dans la requete.

J'espère que les gens qui seront confronté à ce genre de problème à devoir modifier les héritages veuillez passez en

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

@Inheritance(strategy= InheritanceType.SINGLE_TABLE)

Car cela me sauve la vie
