I searched before, but I didn't find any solution. I just like to know a list of users who have the most reputation but only from asking questions.
There's a SEDE query for that:
This user has no answers but 37k reputation (though they might have gained reputation from suggested edits and/or the association bonus as well).
For reference, here is the complete query:
SELECT TOP 100 u.Id AS [User Link], u.Reputation FROM Users AS u LEFT OUTER JOIN Posts AS p ON p.OwnerUserId = u.Id AND p.PostTypeId = 2 -- answers WHERE p.Id IS NULL ORDER BY u.Reputation DESC
