如何將jqpl查詢遷移到Criteria API

Question

請在jpql中有此查詢我想遷移到條件。你怎麼樣？

查詢：

SELECT c FROM Cartera c,Cliente cli WHERE c.aseId = :aseId and cli.aseId=c.aseId 

感謝

Answer 1

CriteriaBuilder cb = em.getCriteriaBuilder(); 
CriteriaQuery<Cartera> query = cb.createQuery(Cartera.class); 
Root<Cartera> cartera = query.from(Cartera.class); 
Root<Cliente> cliente = query.from(Cliente.class); 
query.select(cartera); 
query.where(cb.equal(cartera.get(Cartera_.aseId), theAseId), 
      cb.equal(cliente.get(Cliente_.aseId), theAseId)); 

應該做的伎倆。雖然沒有測試過。

JB Nizet的答案後，你還必須有

TypedQuery<Cartera> tq = em.createQuery(query); 
tq.setFirstResult(offset); // how many records to skip 
tq.setMaxResults(pageSize); // don't want to fetch a million records 
List<Cartera> list = tq.getResultList();
