JPA 2.1 CriteriaQuery between Date


JPA 2.1 CriteriaQuery between Date

hop of those help? How can I use CriteriaQuery with BETWEEN clause in Date? I have tried this without success; , Reviewing your code, it looks like a typo.
You have
code :
// get error here; "The method get(String) in the type Path<Registry> is not applicable for the arguments (String, Date, Date)"
c.select(registry).where(cb.between(registry.get("dateEntry", init, currentDate)));
 Path<Date> dateEntryPath = registry.get("dateEntry");
 Predicate predicate = cb.between(dateEntryPath,init,currentDate);
 c.select(registry).where(predicate);

I hope this helps . After some time, I decided I'm going to implement a different approach to this particular problem. Since I couldn't find any options on how to do this, I attempted to solve it on a JPA implementation level. Since I use Hibernate, I used Hibernate filters. For Eclipselink users: you can use Eclipselink's Multi tenancy feature.
Unfortunately I haven't been able to find a solution on a higher level, so I still have to write a new implementation for this if I were to switch implementations. On the other hand, I probably won't switch to new implementations on a regular basis so that probably won't be an issue.

hope this fix your issue This tutorial explains everything very well. http://www.baeldung.com/jpa-pagination
Just in case link breaks i'll add a segment and add where the where should be put too
code :
int pageNumber = 1;
int pageSize = 10;
CriteriaBuilder criteriaBuilder = entityManager.getCriteriaBuilder();

CriteriaQuery<Long> countQuery = criteriaBuilder.createQuery(Long.class);
countQuery.select(criteriaBuilder.count(countQuery.from(Foo.class)));
Long count = entityManager.createQuery(countQuery).getSingleResult();

CriteriaQuery<Foo> criteriaQuery = criteriaBuilder.createQuery(Foo.class);
Root<Foo> from = criteriaQuery.from(Foo.class);
CriteriaQuery<Foo> select = criteriaQuery.select(from);
select.where(criteriaBuilder.equal(fromRoot.get("entityColumb"), "bar")));

TypedQuery<Foo> typedQuery = entityManager.createQuery(select);
while (pageNumber < count.intValue()) {
    typedQuery.setFirstResult(pageNumber - 1);
    typedQuery.setMaxResults(pageSize);
    System.out.println("Current page: " + typedQuery.getResultList());
    pageNumber += pageSize;
}
