HQL查询

HQL的简单查询

    public static void demo() {
        Session session = HibernateUtils.getCurrentSession();
        Transaction trans = session.beginTransaction();
        
        //简单查询
        // sql中支持 * 的写法：select * from cst_customer; 但是在HQL中不支持* 的写法。
        /*
        Query query = session.craeteQuery("select * from Custome");
        报错 List<Customer> list = query.list();
        */
        String sql = "from Customer";
        Query query = session.createQuery(sql);
        List<Customer> list  =query.list();
        
        for (Customer customer : list) {
            System.out.println(customer);
        }
        
        trans.commit();
    }
