Hibernate Select Top and Bottom n Rows with Criteria

Question

Let\'s say I have two tables, Books and Reviews. Reviews has a column, stars, that can have a value between 1 and 5. A Book can have many Reviews.

How would I select al

Answer 1

You could always set the ordering asc/desc and then limit the results.

ex:

criteria.addOrder(Order.desc("id"));
criteria.setMaxResults(1);

Not sure where it stands with regard to efficiency. I'm assuming that it's doing the filtering after the fact that a Select * has been fired off?
