I would like to query audit entity in my JPA environment.
At first I do AuditQuery
and it works well, but now I need more advance query witch I can't do with AuditQuery
.
Now I need something like
this.em.createQuery("FROM ENTITY_AUD").getResultList();
but I get error :
QuerySyntaxException: ENTITY_AUD is not mapped [ENTITY_AUD]
I understand that this is due that I don't have entity with all properties, but I don't want to have entity because it is audit entity.
Is there a way around it? For me it would be ok to get List of Object.
You can always create native SQL query in JPA. Replace createQuery
with createNativeQuery
in your code:
List<Object[]> list =
this.em.createNativeQuery("SELECT * FROM ENTITY_AUD").getResultList();
Add a NamedQuery in your Audit class
@Entity
@Table(name = "ENTITY_AUD")
@NamedQueries({
@NamedQuery(name = "Audit.findAll", query = "SELECT a FROM Audit a")})
public class Audit implements Serializable {
...
}
then use the named query
List<Audit> auditList = entityManager.createNamedQuery("Audit.findAll").getResultList();
