I am trying to use UNION from Hibernate using createQuery() method.
It seems that the result is unpredictable.

Is there any way in using this feature from HIBERNATE??

Yes, it is. Just use View.

Yes, indeed, but I am using Mysql and views will be implemented somewhere in the 5 version.

Maybe, for complicated query I should stick to JDBC..

It is out of topic, but why do you use advanced tools like hibernate for toys like mysql ? There are a few open source real RDMS implementations: PostgreSQL, SAPDB, Firebird.

You should use createSQLQuery(), not createQuery(). What do you need a union for?
