Question

I have a small racing project that uses a MySQL backend. I am trying to find a good query for grabbing the details of all drivers that have placed in the top 3 positions in more than two races. Here’s a small table breakdown:

Drivers table:
driver_id, driver_name, driver_age, etc misc details

Entry table:
entry_id, driver_id, placed

So, normally this wouldn’t be a huge issue since I could just do a JOIN on driver_id and then use WHERE on my 'placed' column to thin down the results; however, the client absolutely must have the guys who placed in the top 3 more than once. I would just take care of it on the script side of things but the app they are using to pull in the data is very odd.

Thanks!

Answer 1

select *
from `Entry table`
where placed <= 3
group by driver_id 
having count(*) > 1

or something like this… I know you are looking for the having clause on a count statement
