------------------------------------------

looks like you are actually using entitymanager api so here it is @FieldResult you need to use.

> As simples as that:
> 1: Query q = em.createNativeQuery("select cd_person as codePerson, cd_person as identif from PERSON");
> 2: List<Object[]> resultList = (List<Object[]>) q.getResultList();
> Hibernate is ignoring my aliases when retrieving information from the ResultSet because it is trying to retrieve by column name, generating the following error:

> Awesome! The SQL query runs, but the Hibernate try to get the column by the original name, not by the alias, causing the error!
> It is not possible to correctly get the value of 2 different columns that have the same name!!!!
> Hint: why Hibernate use ResultSet.get* by column name instead of positional ResultSet.get* (1, 2, 3,...)? It will solve this problem.
