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;
    }
