Error in my query. But what error??

This query will fail.  Assume all table names, column references, and implied data types are correct.

Can you tell me why? This is a question a recruiter asked in a technical screen. He said I could research it and re-submit my answer.

SELECT Max(r.facility) AS max, 
           partition BY 
           ORDER BY ), 
FROM   request r 
       JOIN request_line rl 
         ON rl.request_id =

Is it a simple sytnax error I am missing, or something more?

"rl.quantity" is in the SELECT clause, but not in the GROUP BY clause

There is no "ra" alias in from clause for which you mentioned column ra.amount. Might be typo or you missed the table.

Besides the previous good inputs, I'm not sure the need of having the MAX() and GROUP BY statements since the ROW_NUMBER function will return distinct numbers making the GROUP BY useless.
