问题
I'm using the dense_rank function in SQL to solve the leetcode 'rank scores' problem(https://leetcode.com/problems/rank-scores/description/):
select Score, dense_rank() over (order by Score) Rank
from Scores
order by Score desc
It always give me the following error:
Line 2: SyntaxError: near '(order by Score) Rank
from Scores
order by Score desc'
I wonder how to make this answer correct? Thanks a lot!
Also, I realized most people use an answer without using the DENSE_RANK function, which is quite confusing since to me DENSE_RANK is probably the most intuitive way to solve the problem. Anyone have any idea? Thanks again!

My SQL does not support dense_rank, it does support other window functions though. Check out this answer for help.
Alternatively you could run the code in another SQL server
