Oracle PreparedStatement Batch Resultat toujours -2

Bonjour à tous,

première fois que j'utilise un Batch via un PreparedStatement pour mettre à jour ou insérer des lignes dans un base oracle.

Il y a quelque chose que je ne comprends pas, le tableau d'entier, retourné lorsque j'exécute le executeBatch, contient uniquement des valeurs -2 alors que les lignes sont mises à jour. Il devrait normalement me retourner la valeur 1.

En fait je dois effectuer une vérification sur le nombre de lignes mises à jour et lever des exception en fonction de ce paramètre.

Voici ma méthode utilisée:

Si rien ne cloche dans mon traitement batch, je vais devoir trouver une autre solution pour effecvtuer mes traitements et vérifications (d'abord un select pour être sur que la ligne existe et ensuite un update sinon exception levée)

If select count(*) --> retourne 1 alors "update" sinon "exception levée".

Merci pour votre aide.
