problème d'exécution des requêtes

problème d'exécution des requêtes - Java - Programmation

Marsh Posté le 06-12-2009 à 10:27:42    

Bonjour,
 
Je voulais faire des requêtes de manipulation d'une base des donnée sous Mysql en utilisant le framework de mappage Hibernate.
Il y a quelques requêtes qui ne s'exécutent pas.
Voici ces requêtes:

Code :
  1. List employe = session.createQuery("from Employe p where p.nom=?","ali", Hibernate.STRING).list();
  2.    
  3.      for (int i = 0; i < employe.size(); i++) {
  4. Employe eps = (Employe) employe.get(i);
  5. System.out.println("nom = " +  eps.getNom());


 
 

Code :
  1. Query query = session.createQuery("from Employe p where p.nom = :bassem" );
  2.      query.setString("bassem", "can" );
  3.       Iterator It = query.iterate();
  5.      while (It.hasNext()) {
  6.         Employe per = (Employe) It.next();
  7.         System.out.println("nom = " + per.getNom());
  8.       }


 
 

Code :
  1. int compteur = ( (Integer) session.createQuery("select count(*) from Employe" ).iterate().next() ).intValue();
  2.         System.out.println("compteur = " + compteur);


Que proposez vous ?
 
Merci.

Exception in thread "main" java.lang.ClassCastException: java.lang.Long  
at hibernateproject.Main.main(Main.java:125)
 
 
c'est plutôt là ton soucis.
 
à la ligne 125 de la classe Main, t'as un cast qui n'est pas bon.

Oui c'est la ligne 125.
 
Pour les 2 autres requêtes pourquoi elles ne s'exécutent pas : ?

Code :
  1. List employe = session.createQuery("from Employe p where p.nom=?","ali", Hibernate.STRING).list();
  2.      
  3.          for (int i = 0; i < employe.size(); i++) {
  4.     Employe eps = (Employe) employe.get(i);
  5.     System.out.println("nom = " +  eps.getNom());


 
 

Code :
  1. Query query = session.createQuery("from Employe p where p.nom = :bassem" );
  2.        query.setString("bassem", "can" );
  3.       Iterator It = query.iterate();
  4.  
  5.          while (It.hasNext()) {
  6.             Employe per = (Employe) It.next();
  7.             System.out.println("nom = " + per.getNom());
  8.           }


 
 
'can' va remplacer 'bassem' qui existe dans la table

tes requêtes ne s'exécutent pas parce que le code avant elles est tout vérolé.
