Oracle SQL Developer中的分析函数抛出错误

Question

I am writing a very simple rank function to calculate the rank for each group by partitioning on some specific columns. The sql looks straightforward for me but I really dont understand why I am getting ORA error. Please find my sql and error as below. Any inputs would be appreciated. Thanks.

SQL :-

 SELECT *,
        RANK() OVER( PARTITION BY STUDENTID,BOOKISBN ORDER BY ISSUEDATE )  "RN"
   FROM BORROWED_BY;

Error:-

ORA-00923: FROM keyword not found where expected
00923. 00000 -  "FROM keyword not found where expected"
*Cause:    
*Action:
Error at Line: 10 Column: 9

Answer 1

When you use SELECT * with other columns, you need to qualify it:

SELECT bb.*,
       RANK() OVER (PARTITION BY STUDENTID, BOOKISBN ORDER BY ISSUEDATE ) as RN
FROM BORROWED_BY bb;
