How to write criteria builder api query for below given JPQL query?
I am using JPA 2.2
.
SELECT *
FROM Employee e
WHERE e.Parent IN ('John','Raj')
ORDER BY e.Parent
This criteria set-up should do the trick:
CriteriaBuilder cb = entityManager.getCriteriaBuilder();
CriteriaQuery<Employee> q = cb.createQuery(Employee.class);
Root<Employee> root = q.from(Employee.class);
q.select(root);
List<String> parentList = Arrays.asList(new String[]{"John", "Raj"});
Expression<String> parentExpression = root.get(Employee_.Parent);
Predicate parentPredicate = parentExpression.in(parentList);
q.where(parentPredicate);
q.orderBy(cb.asc(root.get(Employee_.Parent));
q.getResultList();
I have used the overloaded CriteriaQuery.where
method here which accepts a Predicate
.. an in
predicate in this case.
