[hibernate-issues] [Hibernate-JIRA] Commented: (EJB-214) Native Query can not be used with parameter

Steve Ebersole commented on EJB-214:
------------------------------------

The underlying cause is in o.h.e.QueryImpl in the public Query setParameter(int position, Object value) implementation.  Specifically, the check: if ( isEJBQLQuery() )...  Essentially, if this is an ~HQL query, the parameter is correctly converted to a Hibernate named parameter.  However, in this case, we are talking about a native-sql query; here, the isEJBQLQuery() check evaluates false, and so the parameter is passed on to the underlying Hibernate query object as a ordinal parameter instead.  What was the reason for the distinction here?

There is most definitely a mismatch here.  Hibernate core treats all "?n" (where n is a numeric) sequences as a variation of named parameters...

>
> When using Native Query with parameter, IndexOutOfBoundsException is occurred.
> org.hibernate.engine.query.ParameterParser(Hibernate Core) handles positional parameter as named parameter internally,
> but org.hibernate.ejb.QueryImpl(Hibernate EntityManager) expects positional(ordinal) parameter, not named parameter.
> Here is sample for this issue.
> =======
> Query query = em.createNativeQuery("SELECT d.name FROM Department d WHERE d.id = ?1");
> query.setParameter(1, 1);
> =======
> Result is
> java.lang.IndexOutOfBoundsException: Remember that ordinal parameters are 1-based!
