Hibernate inject Criterion into Query

Question

I have a code with Hibernate restrictions like:

Criterion budgetTypeRestriction;
budgetTypeRestriction = Restrictions.between("code", "01", "03");

And how I can inject Criterion into Query ?:

Session session = sessionFactory.getCurrentSession();
Query query = session.createQuery("from Regions");

It is easy for me collect Criterion logic, and then pass it to DAO, which is implemented throw Query and parameter binding.

Answer 1

In Query (HQL) you don't use Criterion.

Instead you use HQL expressions in where clause which are similar to SQL:

Query query = session.createQuery("from Regions r where r.code between '01 and '03'");

Answer 2

I hope you expect the below

List<Regions> regionsList=sessionfactory.getCurrentSession().createCriteria(Regions.class)
                          .add(Restrictions.between("code", "01", "03")).list();

Answer 3

You probably want to use the Criteria API instead of a query. You can add sql restrictions to a criteria with Restrictions.sqlRestriction() if you need that.
