Java 更新时出现Hibernate错误：无法执行语句，使用正确的语法接近'；指数=1'；

我正在使用带有Hibernate和MySQL的netbeans开发一个桌面应用程序。当我向数据库添加新记录时，它完全正常工作，但当我尝试更新对象字段时，出现以下错误：

could not execute statement

Java代码：

private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {                                         

    Session session = null;


    try {
        session = HibernateUtil.getSessionFactory().openSession();
        session.beginTransaction();

        Student student = (Student) session.get(Student.class, new Integer(1));
        student.setMark(0);
        System.out.println(student.getIndex()+" "+student.getName()+" "+student.getMark());

        session.saveOrUpdate(student);
        session.getTransaction().commit();
        session.close();

    } catch (Exception e) {
        System.out.println(e.getMessage());
    } 

}       

hibernate.cfg.xml：

</hibernate-mapping>

在MySQL和大多数其他关系数据库系统中

您需要将标识符重命名为

id

是否可以启用hibernate生成的实际sql语句的日志记录。请参见“是”，问题出在id列名“index”中。我把它改成“id”后它就开始工作了。
