Hibernate HQL

HQL 결과를 사용자 정의 객체로 전환

Mapping A Hibernate Query To A Custom Class | Baeldung

HQL Constructor

Query<Result> query = session.createQuery("select new com.baeldung.hibernate.pojo.Result(m.name, m.department.name)"
  + " from com.baeldung.hibernate.entities.DeptEmployee m");
List<Result> results = query.list();

ResultTransformer

Query query = session.createQuery("select m.name as employeeName, m.department.name as departmentName"
  + " from com.baeldung.hibernate.entities.DeptEmployee m");
query.setResultTransformer(Transformers.aliasToBean(Result.class));
List<Result> results = query.list();

QueryDSL 사용시에는 Projection 을 사용하면 된다.
