Few suggestions:
Enable configuration parameter show-sql in persistence.xml. Try this, i.e.
<property name="hibernate.show.sql" value="true" />
Furthermore, it is better to format that using,
<property name="hibernate.format_sql" value="true" />
And then try to run the same query in some SQL Client.
