Question

Im struggeling to understand Hibernate HQL, being only used to sql, i dont understand whats wrong with my HQL. Any help would be greatly appriciated:

@Entity
public class KursKode {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private long id;
private String kursKode;
private boolean used;

@ManyToOne
@JoinColumn (name = "kursId")
@LazyCollection(LazyCollectionOption.FALSE)
private Kurs kurs;
....
}

Im trying to fetch only “KursKode”‘s for a specific Kurs. And only “KursKodes” that have “used=false”. So i tried this in my DAO:

List<KursKode> kursKodeList = getHibernateTemplate().find("from KursKode k where k.kurs.kursId = ? and not k.used", kursId);

But this gives me the following error:
Data Access Failure

unexpected AST node: . near line 1, column 74 [from no.dahlsdata.model.Kurs.KursKode k where k.kurs.kursId = ? and not k.used]; nested exception is org.hibernate.hql.ast.QuerySyntaxException: unexpected AST node: . near line 1, column 74 [from no.dahlsdata.model.Kurs.KursKode k where k.kurs.kursId = ? and not k.used]

Answer 1

Problem was only small. I forgot to put =false on the end. Here is what it should be:

List<KursKode> kursKodeList = getHibernateTemplate().find("from KursKode k where k.kurs.kursId = ? and not k.used=0", kursId);
