Sql server sql server到oracle查询转换

我需要将SQL Server查询转换为Oracle，有人能帮忙吗

WITH e AS
(
     SELECT *,
         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

---

如果

select

子句中有其他列，Oracle要求您在星号前面加上前缀：

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
