My native query below is working fine oracle sqlplus. But through JPA native query, giving following error:
[ERROR] org.hibernate.util.JDBCExceptionReporter – ORA-00923: FROM keyword not found where expected

JPA native query will not transform resultset into list of supplied type of DTO :(. We need to do explicitly.
