Question on Query service
Can I use the Query service direclty, to retrive data from two or more table by joining them and with out having a persistant objects for the above said tables.
If this is possible please let me know how to do that.

I think you have a fundamental misunderstanding. The query service is a bunch of classes and interfaces that provide services to the persistence framework.
Look at this
These Object Services include:
· A Persistence Service, used to manage persistent objects in the database
· A Transaction Service, used to update persistent objects
· A Query Service, used to search for and load persistent objects.
