For a custom triggered one, I think you should be able to steal the Campaigner query and tweak it to work for badges instead of invites.
This one is for having 5 ‘Badge 108’, and would be set to update daily.
SELECT u.id user_id, current_timestamp granted_at
FROM users u
WHERE u.id IN (
FROM user_badges ub
WHERE ub.badge_id = 108
GROUP BY ub.user_id
HAVING COUNT(*) >= 4
) AND u.active AND u.silenced_till IS NULL AND u.id > 0 AND
(:backfill OR u.id IN (:user_ids) )
I’ve tested it briefly on my test site and it seems to work okay (I trigger the Badge Grant sidekiq job to speed up the wait). But hopefully that at least gives you a starting point to build from.

It looks like you ran that in the data explorer. For the custom SQL badges you would need to turn on the hidden site setting and add the query to the badge page:
However, not everyone can do that depending on their hosting package.
But a data explorer one is more than possible too if you can’t have the custom SQL triggered ones. I think you’d have to make some choices about how often you ran it, and how the Badges would be awarded from the results (manually one by one, or through the bulk award), but it’s definitely do-able.
Something simple may be better, though you perhaps want to add a date range parameter too?
WITH foo AS (SELECT ub.user_id,count(ub.user_id), max(ub.granted_at) granted_at
FROM user_badges ub
GROUP BY ub.user_id)
SELECT user_id, granted_at
WHERE count >4
ORDER BY granted_at DESC
That’s great. I find copying the existing badge queries and having a tweak quite useful to give me an idea of where to start. I’m sure they can then be refined further as well if you encounter any issues with one.
