Get record with max id, using Hibernate Criteria

Question

Using Hibernate\'s Criteria API, I want to select the record within a table with the maximum value for a given column.

I tried to use Projections, creating an alias

Answer 1

    Date maxDateFromDB = null;
    Session session = (Session) entityManager.getDelegate();
//Register is and Entity and assume maxDateFromDB is a column.
//Status is another entity with Enum Applied.
//Code is the Parameter for One to One Relation between Register and Profile entity.
    Criteria criteria = session.createCriteria(Register.class).setProjection(Projections.max("maxDateFromDB") )
    .add(Restrictions.eq("status.id", Status.Name.APPLIED.instance().getId()));
    if(code != null && code > 0) {
        criteria.add(Restrictions.eq("profile.id", code));
    }
    List list = criteria.list();

    if(!CollectionUtils.isEmpty(list)){
        maxDateFromDB = list.get(0);
    }
