Hibernate - update the primary key 'id' column in the table


In my Java applicaion, I am using hibernate .hbm file to access database; Is this possible to update the primary key 'id' column in the table; Where the 'id' column in my .hbm file is like:

<hibernate-mapping package="org.jems.user.model">
<class name="Student_Details" table="t_student">
<id name="id" type="int" column="id">
<generator class="increment"/>
</id>
<property name="name" column="name" type="string" unique="true" not-null="true" />
<property name="description" column="description" type="string"  />
<property name="comments" column="comments" type="string"  />
<property name="active"     column="isActive"   type="boolean"  not-null="true" />
</class>
</hibernate-mapping>

Solution

  • try this:

    String hql="update table set id=? where id=? ";
    Query query=HibernateSessionFactory.getSession().createQuery(hql);
    query.setInteger(0,1);
    query.setInteger(1,2);
    query.executeUpdate();
    HibernateSessionFactory.getSession().beginTransaction().commit();
    

    or just use sql:

    String sql = "update table set id = ? where id= ?"
    Session session = HibernateSessionFactory.getSession();  
    SQLQuery query = session.createSQLQuery(sql);
    query.setParameter(0, 1);
    query.setParameter(1, 2);
