Question

Let's say I have a table that stores user info with each row structured like:

(int) FileId |(int) userId | (int) DownloadHits | (varchar) UserName

Each user may have a lots of files uploaded by their names. I want to show a list of user that have top download hits, look like :

userId    UserName     DownloadHits
  1          Key             120  
  2          Bob             50  
  3          Zero            15  

I tried SUM method but it only show the top one user. Is there any solution for this query ?

Answer 1

select userid,username,
sum(downloadhits) as theDowns
from tblName
group by userid,username
order by theDowns desc
