这个SQL查询语句中的最后一行存在问题，因为Oracle数据库中的rownum是伪列，它的值是在查询结果返回之后才会进行计算，所以在查询语句中直接使用rownum是没有意义的。将该查询结果再次进行筛选，需要使用子查询或者其他方法。

如果想要查询前N条记录，可以使用如下SQL语句：

SELECT * FROM (
  SELECT TO_CHAR (f_hand_date, 'yyyy-MM-dd') AS f_hand_date, MIN (F_LAST_TABLEBASE) AS F_LAST_TABLEBASE, MAX (F_TABLEBASE) AS F_TABLEBASE, SUM (F_OUGHTAMOUNT) AS F_OUGHTAMOUNT, SUM (F_OUGHTFEE) AS F_OUGHTFEE 
  FROM T_HANDPLAN 
  WHERE f_userinfo_id = '10155142' 
  AND F_HAND_DATE >= TO_DATE ( '2023-05-01 00:00:00', 'yyyy-mm-dd hh24:mi:ss' ) 
  AND F_HAND_DATE <= TO_DATE ( '2023-05-31 23:59:59', 'yyyy-mm-dd hh24:mi:ss' ) 
  GROUP BY TO_CHAR (f_hand_date, 'yyyy-MM-dd')
  ORDER BY f_hand_date ASC
) WHERE ROWNUM <= :1;

其中，ORDER BY语句用于对查询结果进行排序，ASC表示升序排列，DESC表示降序排列。最后使用ROWNUM进行筛选，获取前N条记录。
