Isn't there a way, as I'm not to familiar with
sql and hql to get an
empty line from my result. So like selecting what I select in my query

this can be done in HQL, I would be interrested in how to do it.
This is usually accomplished with UNION clauses in standard SQL.
Unfortunately HQL does not support it. So the ugly hack provided by
Guillaume is the only solution I know.
