Question

I have a MySQL query like this:

SELECT * 
FROM backstage 
WHERE backstage_id IN (
    SELECT backstage_id 
    FROM visitor_counter 
    WHERE backstage_id !=0 
    GROUP BY backstage_id 
    ORDER BY COUNT( DISTINCT ( ip_address ) ) DESC 
) 
LIMIT 0 , 100

I get the results I want, but I would like to order it by COUNT( DISTINCT ( ip_address ) ) DESC as the inner question does.

Any tips on how to do this?

Give this a go and see if it gives you what you’re after:

select bs.*
from backstage bs
inner join
(
select backstage_id,count(distinct ip_address) as distIpCount
from visitor_counter
where backstage_id !=0
group by backstage_id
) vc on vc.backstage_id = bs.backstage_id
order by vc.distIpCount desc
limit 0,100;
