    Affects Versions: 3.4.0.GA

Hi,

A very simple usage of SqlResultSetMapping. I want to retrieve only country Name using native query. I have specified one column country name to be fetched and mapped in Object.

@SqlResultSetMapping(name = "CountryCountry", entities = { @EntityResult(entityClass = Country.class, fields = { @FieldResult(name = "countryName", column = "COUNTRY_NAME") })

 public void testComplexer0NativeQuery() {
        em = emf.createEntityManager();
        Query query = em.createNativeQuery(
                "select iso.COUNTRY_NAME from Country iso",
                "CountryCountry");
        List list = query.getResultList();
        System.out.println(list.size());
        System.out.println(list.get(0).getClass());
    }

Running this I get   "INFO: could not read column value from result set: ISO1_2_0_; Invalid column name" exception. The whole stack trace :

Hibernate is trying to fetch all the columns present in entity to create the object. I am only interested in column/s I have specified in "@FieldResult".

If I retrieve all fields in entity, It works fine though.

Thanks and Regards.
