Untitled query #77504

SQL

#Preliminary approach: return user edit counts, a field already tracked by wikis. 
#caveats: not accurate, for details refer to Manual:user table, user_editcount
#time complexity: slow for large wikis/more users
#includes bots
SELECT user.user_id, user.user_name, user.user_editcount FROM user
INNER JOIN user_groups ON user.user_id = user_groups.ug_user
WHERE user_groups.ug_group != 'bot'
ORDER BY user_editcount DESC
LIMIT 10

#Inner join / Extracting all revisions made by all users that have made a revision in this wiki
#SELECT actor.actor_name, COUNT(revision.rev_actor) AS Edits
#FROM actor
#INNER JOIN revision ON actor.actor_id = revision.rev_actor
#GROUP BY actor.actor_name
#ORDER BY Edits DESC
#LIMIT 10

#Interestingly, the two approaches above result in slightly different rankings
#Some user edit counts are undercounted and some are overcounted in the first approach
#Since it doesn't involve a join, first approach is faster
