When I run this code,
.....
int id = 20; //Id is the primary key in the db table
Query query = em.createNativeQuery("select p.* from Person where p.id = " + id);
log.debug(query.getResultList());
.......
I get the following exception:
Exception in thread "main" javax.persistence.PersistenceException:
