I have a Utilisateur class and a login class with the following file mapping :
<class name="com.cfort.utilisateur.Login" table="login">
<id name="id" column="identifiant" type="string" length="20">
<generator class="assigned"/>
</id>
<property name="motPasse" type="string" length="20"/>
<property name="dernierLogin" type="date"/>
<one-to-one name="utilisateur" class="com.cfort.utilisateur.Utilisateur"/>
</class>
<class name="com.cfort.utilisateur.Utilisateur" table="utilisateur" discriminator-value="U">
<id name="id" column="identifiant" type="string" length="20">
<generator class="assigned"/>
</id>
<discriminator column="type" type="character"/>
<property name="dateAbonnement" type="date"/>
<property name="datePaiement" type="date"/>
<property name="modeReglement">
<column name="modeReglement" sql-type="varchar(30)"/>
</property>
<property name="nbPoints" type="integer"/>
<one-to-one name="login" class="com.cfort.utilisateur.Login"/>
<subclass name="com.cfort.utilisateur.Particulier" discriminator-value="P">
<property name="nom" type="string" length="30"/>
<property name="prenom" type="string" length="30"/>
<property name="dateNaissance" type="date"/>
</subclass>
<subclass name="com.cfort.utilisateur.Entreprise" discriminator-value="U">
<property name="raisonSociale" type="string" length="60"/>
<property name="nbSalarie" type="integer"/>
<property name="numInsee" type="string" length="20"/>
</subclass>
</class>
When i insert a new user, i need to know if the id already exists. So i write the code below :
Code:
public boolean existe(String id)
{
try
{
Session session = HibernateDAOFactory.creerConnection();
Transaction tx = session.beginTransaction();
Utilisateur u = (Utilisateur) session.load(Utilisateur.class, id);
tx.commit();
if (u == null)
return false;
else
return true;
}
catch(Exception e)
{
e.printStackTrace();
return false;
}
}
When i execute the method, i have the following error message
INFO: Query language substitutions: {}

Hibernate: insert into utilisateur (nom, prenom, dateNaissance, dateAbonnement, datePaiement, modeReglement, nbPoints, type, identifiant) values (?, ?, ?, ?, ?, ?, ?, 'P', ?)
Hibernate: insert into login (motPasse, dernierLogin, identifiant) values (?, ?, ?)
Can someone explain to me the meaning of the error and how can i test
if a record with the id typed is already store in the DataBase
Thanks
