hi,

i need help to do an query like that :

Query q = HibernateUtil.getSession().createQuery("FROM AC_param param WHERE param.param_name = ? AND param.ac_id = ?");

q.setText(0, param_name , ac_id );

How i can replace first ? by param_name and the second ? by ac_id ?

Hello,

You need to do something like this:
q.setText(0, param_name);
q.setText(1, ac_id);

or

q.setString(0, param_name);
q.setString(1,ac_id);
