Hi Koushik.
Really admire your work :)

I have a question that i can't find the answer to:

Hibernate doesn't consider primary key for Example object---but why?
What's the benefit of this feature?
Thanks in advance

Thanks a lot for your tutorials! I would like to retrieve Hibernate query result as result set instead of list. For example with ResultSet (JDBC) I can do resultSet.getString(index) or In List, apparently I can't do so. Is there anything that I could do for that?

Hi good explanation. I want to know how to use query by example for "or" logical operator because in this example you showed query by example using "and" logical operator and that is by default.
