Question

when to use detached criteria? and what is the advantage we get by using detached criterias instead of normal criteria?

Criteria criteria = sessionFactory.getCurrentSession().createCriteria(Some.class);


DetachedCriteria criteria = DetachedCriteria.forClass(Some.class);

Thanks!

Answer 1

As per docs

Some applications need to create criteria queries in “detached mode”,
where the Hibernate session is not available. This class may be
instantiated anywhere, and then a Criteria may be obtained by passing
a session to getExecutableCriteria(). All methods have the same
semantics and behavior as the corresponding methods of the Criteria
interface.
