Just to make sure you did everything correct :

1) Check your database you have data inside your UserDetails table.
2) Before running HQL, make sure you change your configuration "hbm2ddl.auto" from "create" to "update".
3) Then try again. If not working step back to the first step :)

Because there is no reason not to fetch data from database in this simple example.

Hi Kaushik, I have an sql in which I apply a join in result of a subquery and a separate table, eg.

Select * from student_fees fees join (select max(I'd), section from student where I'd =1 group by section) as std on std.id = fees.id .

I want something like this in hql. Here I am fetching the last student of each section and making join with feel table. Please let me know if hql with same purpose can be created.

Also I do not need an 'in' clause because that breaks with more than 1k records.

Query is deprecated now, does anybody knows the alternative?

Dont import QUERY from “org.hibernate” (as its Deprecated now). Instead import from “org.hibernate.query” .

Great tutorial series Koushik. One question regarding this tutorial and HQL: I believe the main reason behind using an ORM framework like Hibernate was to avoid writing database queries. I get that with HQL we are not writing exact SQL queries and its somewhat object-oriented but essentially we are doing the same thing as passing SQL queries through JDBC but in a slightly different syntax. Doesn't this defeat the major purpose of using Hibernate?

Hi, your tutorial is great, thank you very very much.
I have a question: The session.createQuery("from UserDetails") returns me no results!
And i did the same what u did in the tutorial. I googled but i couldnt find the problem.
Can u help me to continue the next parts of the tutorial please?
Thank u so much

Sir, you haven't explained the reason for org.hibernate import instead of JPA.
