Column alias results in ORA-00972

Question

Hi,
I am using Eclipselink v1.0.2 on glassfish.
I have a query where I have set the maxResults to 1 like so:
this.entityManager.createQuery("SELECT t FROM Tbl t where t.name='271040300018**'")
                    .setMaxResults(1)
                    .getResultList();
The resultant query contains a column alias that has more than 30 characters which causes an ORA-00972 error. I've noticed that if I don't call setMaxResults the query does not contain aliased column names. Is there a way to either make sure that the query generator does not generate invalid column names or get it to not alias columns when I have a result set limit?
Thanks,
Drew

Answer 1

Here is the generated query with the problematic aliases bolded. Note that I cannot change the length of the non aliased column names as a workaround.
Thanks,
