HQL的第一个程序

　　　　//1获取query对象
        String hql="FROM Employee e where e.salary>?";
        Query query=session.createQuery(hql);

        //2绑定参数
        query.setInteger(0, 100);

//1. 创建 Query 对象
        //基于命名参数. 
        String hql = "FROM Employee e WHERE e.salary > :sal AND e.email LIKE :email";
        Query query = session.createQuery(hql);
        
        //2. 绑定参数
        query.setFloat("sal", 7000)
             .setString("email", "%A%");

  String hql = "FROM Employee e.dept = ? ";       
  Query query=session.createQuery(hql);
  Department dept = new Department();
        dept.setId(80); 
        query.setEntity(2, dept);    

//3执行查询
        List<Employee> emps=query.list();
        System.out.print(emps.size());
