求教ORA-30485: 在窗口说明中丢失 ORDER BY 表达式问题解决办法

在网上找了很多关于在窗口说明中丢失 ORDER BY 表达式问题解决办法的问题解决方法，都没有找到具体解决办法，求助各位大神。

SELECT n.id, n.NAME,n.fileType,n.path,u.nameCh AS
    "author",n.uploadDate,s.skillName,n.readTimes,n.downTimes,n.iconcss,
    (SELECT count(fid) FROM his_knowledge WHERE fid = n.id) AS "hisCounts",
    (SELECT count(fid) from message where fid = n.id ) as "leaveMsg",vf.verifydate
    FROM
    KnowLedge n,skillInfo s,userInfo u,
    (SELECT *
    FROM (SELECT ROW_NUMBER()  OVER(PARTITION BY FID order by   VERIFYDATE DESC) rn,
               verifyinfo.*
          FROM verifyInfo)
    WHERE rn = 1) vf
    WHERE s.skillId = n.skillId
    and n.id= vf.fid
    AND
    u.userId = n.author
    AND n. STATUS = 0
    AND n.verify = 1

    AND n.isleaf = 1

这个sql在PL/SQL中可以正常运行，但是放在ibatis中报错;
