Is it that HQL has the limitation that joins between tables cannot be established in a query, which are not related to each other using PK/FK relationship?
If it can be done, can i have a sample example HQL query.

Thanks,

You can do it in the same way you can do this in SQL:

That being said, why join unrelated entities? If they are not related, why write a query that treats them as if they are?
