Max Rydahl Andersen commented on HHH-2167:
------------------------------------------

the docs describe this and have examples for it...especially in 3.2.

don't use the bug tracking system for for usage questions use the docs and the forum.

> You will see lots of people like me & my team who would like to leverage the flexibility of SQL & persistence management of Hibernate  . So for user community like us who come with a strong background of SQL experience Hibernate 3 is the way to go even for simple or complex queries. Not sure whether any performance is involved here. But i am able to run even a simple sql query using hibernate3 . 
> public List getUser(final String bemsId) throws DataAccessException {
> HibernateTemplate ht = new HibernateTemplate(this.sessionFactory);
> return (List) ht.execute(new HibernateCallback() {
> public Object doInHibernate(Session session) throws HibernateException {
> Query query = session.createSQLQuery("select c.last_name, c.first_name from user c where c.userid=?");
> ((SQLQuery) query).addScalar( "last_name", Hibernate.STRING); 
> ((SQLQuery) query).addScalar( "first_name", Hibernate.STRING); 
> query.setString(0, userId);
> return query.list();
> }
> });
> }
>  Note : I have  even tried addEntity("user", User.class) but it doesnt work
> This is how i retrieve 
>  for (Iterator it = user.iterator(); it.hasNext();) {
>                      User user = (User) it.next();
>                      System.out.println("LastName: " + user.getLastName());
>                      System.out.println("FirstName: " + user.getFirstName());
>                    }
> I get a ClassCast Exception error or Bad Grammer error . 
> I am quite suprised to know When i used : addEntity("user", User.class) i got invalid Column error with Bad Grammar
> Any pointers/suggestions to write simple/complex sql  queries in Hibernate with examples will be highly appreciated. Pl note we dont want to use HQL
