I think today is the second or maybe third day when Hibernate’s documentation has been inaccessible.

Thank god for Google cache !!!

Well I hope it gets back soon.

UPDATE: Seems like its back!!!


The error message

Named query not known: my.simple.query
    [junit] org.hibernate.MappingException: Named query not known: relationship.delete_by_userId
    [junit]  at org.hibernate.impl.AbstractSessionImpl.getNamedQuery(AbstractSessionImpl.java:93)
    [junit]  at org.hibernate.impl.SessionImpl.getNamedQuery(SessionImpl.java:1287)

The context

You are using a named query in your application. Named queries are externalized and are coded in the hibernate mapping files rather than the application code

Possible reason(s) for this error

1) The name of the query in the hibernate file doesnt match with what you have in the code. Both should match exactly

2) You have defined the query inside the class definition. A hibernate mapping file can have multiple class definitions (not a recomended or much practised approach though). A named query must exist outside the class definition.


<query name=”my.simple.query”>delete from Users as user where user.id =?</query

Session session = sessionFactory.openSession();
Query query = session.getNamedQuery(“my.simple.query”);
query.executeUpdate ();

Did this solve your problem ?

Please let me know. Thanks !!!
