• 벌크연산(update) 후 em.clear() 로 영속성 컨텍스트 초기화

• 다시 객체 조회를 해서 프린트문을 입력했는데 결과가 변하지 않습니다

JPQL

em.flush();
em.clear();

String query = "update Member m set m.age = 30";
em.createQuery(query).executeUpdate();

em.clear();

Member m3 = em.find(Member.class, member3.getId());

System.out.println("member3.getAge() = " + member3.getAge());

tx.commit();
