createQuery 与 createNativeQuery 区别

iabernate 中createQuery与createSQLQuery区别，使用经验 
createQuery与createSQLQuery两者区别是： 


前者用的hql语句进行查询，后者可以用sql语句查询 

前者以hibernate生成的Bean为对象装入list返回 

后者则是以对象数组进行存储 

所以使用createSQLQuery有时候也想以hibernate生成的Bean为对象装入list返回

如下示例：

@Override
	public List findCommodityByActyId(int activityId) {
		String sql = "SELECT aa.ACTIVITYSCOPE_VALUE from activity_scope aa LEFT JOIN activity_rule ar ON aa.ACTIVITYRULE_ID = ar.ACTIVITYRULE_ID LEFT JOIN"
				+" activity ac on ar.ACTIVITY_ID = ac.ACTIVITY_ID where ac.ACTIVITY_ID ="+activityId+" and ac.status=3";
		System.out.println(sql);
		Query query = entityManager.createNativeQuery(sql);
		List commoditiyIds = (List)(query.getResultList());
		List commodities = new ArrayList();
		for(int i=0;i
