Answer 1

As we discussed in the comments, the issue was in dialect.
Latest dialect for now - org.hibernate.dialect.PostgreSQL95Dialect
The issue solved this dialect:
<prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</prop>
Answer to your HQL-code:
I would suggest using TypedQuery as it returns not just a list, but list of your object.
Furthermore, u are using the same session to transfer data. This is bad for the program. Always do like Open session - transfer data - close session.
Try this code:
public List<Vw_dh_assay> listAssayReport(double year, String project_id, String hole_id) {
List<Vw_dh_assay> list = new ArrayList<>();
Session session;
try {
session = this.sessionFactory.openSeesion();
TypedQuery<Vw_dh_assay> query = session.createQuery("from Vw_dh_assay where year = :year AND project_id = :project_id AND hole_id = :hole_id", Player.class);
query.setParameter("year", year);
query.setParameter("project_id", project_id);
query.setParameter("hole_id", hole_id);
list = query.getResultList();
System.out.println(list);
session.clear();
session.close();
} catch (Exception e) {
e.printStackTrace();
}
return list;
}

Answer 2

this is my code DAO #Antonio112009
#Override
public List<Vw_dh_assay> listAssayReport(double year, String project_id, String hole_id) {
Session session = this.sessionFactory.getCurrentSession();
String query = ("SELECT DISTINCT year,project_id,hole_id from "
+ "Vw_dh_assay where year = :year AND project_id = :project_id AND hole_id = :hole_id");
List result = session.createQuery(query).setParameter("year", year).setParameter("project_id", project_id)
.setParameter("hole_id", hole_id).list();
System.out.println(result);
return result;
}
