         ROW_NUMBER() OVER
         (

             ORDER BY dojoin DESC

【解决方案1】：

如果select 子句中有其他列，Oracle 要求您在星号前加上前缀：

WITH e AS
(
     SELECT Dept.*,
         ROW_NUMBER() OVER
         (
             PARTITION BY fname
             ORDER BY dojoin DESC
         ) AS Recency
     FROM Dept where deptno= 55
)
SELECT *
FROM e
WHERE Recency = 1 
order by fname
