Question

Basically, I’m using this query to group a bunch of users based on the sum of numbers associated with them. I need to some how assign an index to each result. I am blanking on how to do this. I’m thinking I need to alias something with AS but not sure quite how. Any ideas?

This is the current query where I switch out the page and per dynamically:

SELECT COUNT(*) as count, user_id, SUM(earnings) as sum FROM ci_league_result
 GROUP BY user_id ORDER BY sum desc LIMIT ".$page.', '.$per;

I’m lookin for it to work something like this:

SELECT COUNT(*) as count, user_id, SUM(earnings) as sum, *NEW-RESULTS-OVERALL-INDEX* AS newindex FROM ci_league_result
GROUP BY user_id ORDER BY sum desc LIMIT ".$page.', '.$per;

notice the AS newindex in the second query.

Thanks for your advice!

Try this:

SELECT user_id, count, sum, @row := @row + 1 AS newindex FROM
(SELECT
   COUNT(*) as count,
   user_id,
   SUM(earnings) as sum
FROM ci_league_result 
GROUP BY user_id ORDER BY sum desc LIMIT ".$page.', '.$per) r
CROSS JOIN (SELECT @row := 0) rr;
