异常信息:org.hibernate.exception.SQLGrammarException: could not execute query,大家帮帮忙好吗
这是mani方法:
Session ss = HbUtil.getSession();
Transaction trans = ss.beginTransaction();
//Person per = new Person();
Query query = ss.createQuery ("from Order as order");
for (Iterator it = query.list().iterator(); it.hasNext();) 
{
Order order = (Order) it.next();
System.out.println(order.getOrderId()+"&nbsp; " + order.getMateriel()+ "<br>");
}
trans.commit();
ss.close();
System.out.println("Done");

这是hibernate实体类配置文件

<many-to-one name="person" class="Person" column="person" not-null="false"></many-to-one>

------解决方案--------------------
把代码改成这样试试
Session ss = HbUtil.getSession();
Transaction trans = ss.beginTransaction();
//Person per = new Person();
Iterator it = ss.createQuery ("from Order ").list().iterator(); 
while ( it.hasNext()) 
{
Order order = (Order) it.next();
System.out.println(order.getOrderId()+"&nbsp; " + order.getMateriel()+ " <br>");
}
trans.commit();
ss.close();
System.out.println("Done");
------解决方案--------------------
"from Order as order" ==> "from Order order"
