谁能帮我看看这样写为什么不对啊

public List<dashiji> showDashiji(final MyPagination mypage, int zuzhiid) {
        String sql = "select count(*) From dashiji  where zuzhiid=" + zuzhiid;
        SQLQuery query = this.getSession().createSQLQuery(sql);

        int totalRecord = ((BigInteger) query.list().get(0)).intValue();
        mypage.setTotalRecords(totalRecord);
        mypage.setTotalPages(mypage.getTotalPages());

        final String sql2 = "select * from dashiji where zuzhiid=" + zuzhiid
                + " order by id desc";
        // return (List<dashiji>) this.getHibernateTemplate().execute(
        // new HibernateCallback() {
        // public Object doInHibernate(Session session)
        // throws HibernateException, SQLException {
        // SQLQuery query2 = session.createSQLQuery(sql2);
        // query2.addEntity("d", DaShiJi.class);
        // query2.setFirstResult((mypage.getCurPage() - 1)
        // * mypage.getPageSize());
        // query2.setMaxResults(mypage.getPageSize());
        // return query2.list();
        // }
        // });

        SQLQuery query2 = this.getSession().createSQLQuery(sql2);
        query2.setFirstResult((mypage.getCurPage() - 1) * mypage.getPageSize());
        query2.setMaxResults(mypage.getPageSize());
        return query2.list();
    } 
错误提示：
org.hibernate.MappingException: No Dialect mapping for JDBC type: -1

如果用注释了的那段代码就没问题了，这是怎么回事啊，大家帮帮忙，我是个新手，谢谢

将[code="java"]query2.addEntity("d", DaShiJi.class); [/code]改成[code="java"]query2.addEntity(DaShiJi.class); [/code], 如果不行, 能不能贴出整个stack信息和你的配置文件!

我说的stack信息是指整个异常堆栈
