Hi I have a big problem againts
a using hibernate 2.8
this is my code

Code:

public InnerClass batch(List<Infogene> liste) throws HibernateException {
      Session session = null;
      List list = null;
      Transaction tx = null;
      int nbEnrModifie=0;
      int nbEnrEnregistre=0;
      String mgsError = null;
      try {
         session = HibernateUtil.currentSession();
         tx = session.beginTransaction();
         AvinfogePojo pojo= null;
      
         for (Infogene element : liste) {
            mgsError=" le num de dossier est :" + element.getNoDossier();
            if(("3496".trim()).equals(element.getNoDossier().trim()))
               mgsError=" le num de dossier est :" + element.getNoDossier();
            /*list =session
                     .createQuery(
                           " select from AvinfogePojo as base  where base.id.noDossier = ?")
                     .setString(0, element.getNoDossier().trim()).list();*/
            
            list = session
            .find("from AvinfogePojo as base  where base.id.noDossier = ?",element.getNoDossier().trim(),Hibernate.STRING);

         if(list.size()>0)
         {
            pojo = (AvinfogePojo) list.get(0);
            updatePojo(element,pojo);
            session.update(pojo);
            nbEnrModifie++;
         }
         else
         {
            pojo = this.creerPojo(element);
            session.save(pojo);
            nbEnrEnregistre++;
         }         
      
      }
         tx.commit();
         InnerClass rep = new InnerClass(); 
         rep.setNbEnrEnregistre(nbEnrEnregistre);
         rep.setNbEnrModifie(nbEnrModifie);
         rep.setNbEnrModifie(nbEnrModifie);
         return rep;

      } catch (HibernateException e) {
         if (tx != null)
            tx.rollback();
         
         throw new ServiceException(e.getMessage()+ mgsError, e);

      }

      finally {
         
         
         HibernateUtil.closeSession();
         
      }
   }

and the console

1) It is no possible that is (FACTCAN.AVINFOGE_INDEX1) violated
first my not doing a insert. it is a Find

2) I don t know what is the process of hibernate for the sql execute
I check in my that base and the no problem with IG_NO_DOSSIER 3496

FACTCAN.AVINFOGE_INDEX1

Code:

CREATE UNIQUE INDEX "FACTCAN"."AVINFOGE_INDEX1" ON "FACTCAN"."AVINFOGE" ("IG_NO_GROUPE", "IG_NO_CERTIFICAT", "IG_DT_EVENEMENT", "IG_NO_DOSSIER")

if a look for the error
hibernate try to Inserting IG_NO_DOSSIER 5814

IG_NO_DOSSIER = 5814
and this is not the IG_NO_DOSSIER try to execute
even of that I check in my dataBase for IG_NO_DOSSIER = 5814 and
evething is ok there is no (FACTCAN.AVINFOGE_INDEX1) violated
for this to.
by a why make a find not a insert

Ok, you are doing a find, but after the find you are doing some update and create operation as well. So you should try to debug, frm where the insert statement is comming. May be the Infogene liste has some duplicate elements or you are doing something wrong in your updatePojo method. I am pretty sure that the problem is in your logic or the data.

Do you do something with the same session before executing the find? maybe in another method? Because a session is flushed before executing hql, which could cause an insert.

OK it is true littypreethkr that I make operations save and update on the same method.
But when I do step by step. I arrive the find method.

I erase the console. And it is from the method find. That it spits the instructions insert and throws me a HibernateException.

I am going to try the idea of mmerder. Open a second session.

But my question is when I open the second session. Is not expensive.
I always heard that open the second session becomes very expensive. Besides risking errors of concurrence.

I return to you her(it) above thank littypreethkr , mmerder and the 34 person who read my subject

so I very tire of that. It make loose a lot of time.

At first my program worked.
But I pass on my method line by line. Thus a commit every line. I decided to put all element on one list and to make one committed only once. Dad ideal a this time the the nightmare began
