Calculate total affiliated count per user

Question

I've been looking for a simple SQL query to solve a very simple problem. I have been running a very simple social sharing campaign and we have a mysql database with 2 fields: email and AffiliateID

SELECT
users.Email, users.ID,
users.AffiliateID,
Count(users.AffiliateID) as afid
from users
order by afid desc

When I run this query it only returns 1 record with the correct count only the highest count.

What I would like is a list of all the users sorted by the people who have the most 'affiliateID' records in the database.

That will tell us who to give the first prize in the sharing contest to.

Here are some similar questions in here but those solutions don't seem to apply for this situation.

What I would like is a descending output of all the users in the system RANKED by their parent (sponsor) so we can build something akin to a 'leader board'

Group By Count and Total Count

MySQL: Count total in Group by Query

Thank you for your help!

here's updated query

select u.Email, AffiliateID, count(u.AffiliateID) as afid
from users u
where SiteID=17
group by u.Email
order by afid desc 

this generates the image above...

but that's not what I need. What I need is for the 509218 user to show up first and then the count of how many users he's referred followed by the next user 5dd.. then in third place and fourth place would be 471 and 472 with a tie.

Answer 1

You should add group by (to get results per user) clause:

select u.AffiliateID, count(u.Email) as afid
from users u
group by u.AffiliateID
order by afid desc

If you need more data from your users table you can join result of the query below with users table:

select u.ID, u.Email, t.afid
from users u
join (
  select AffiliateID, count(ID) as afid
  from users
  group by AffiliateID
) t on u.ID = t.AffiliateID
order by t.afid desc
