Question

您好我在执行以下查询时遇到了DataException：

 GET_USERLIST_BY_GROUP1 =   "   SELECT usr.user_id,
       usr.login_name
FROM user_info usr
WHERE usr.user_id IN
    (SELECT g.user_id
     FROM group_privilege_details g
     WHERE g.group_id IN
         (SELECT gp.group_id
          FROM group_privilege_details gp,
               user_info u
          WHERE u.user_id=gp.user_id
            AND u.login_name=?)
     GROUP BY g.user_id HAVING count(g.group_id) =
       (SELECT count(g.group_id)
        FROM group_privilege_details gr,
             user_info us
        WHERE us.user_id=gr.user_id
          AND us.login_name=?))
  AND usr.login_name!=?"

请找到一块休眠代码：

qry = hiberSession.createSQLQuery(GET_USERLIST_BY_GROUP1);
qry.setParameter(0, argUsername);
qry.setParameter(1, argUsername);
qry.setParameter(2, argUsername);
lstUsernamebyGroup = qry.list();

请找我的例外：

我唯一看到与你的SQL略显不同的是你使用“！=”不相等的事实。官方不等于SQL的运算符是“＆lt;＆gt;”。 Postgres也支持“！=”，但也许Hibernate有问题。

DataException无法执行查询
