MySQL Getting results for a specific user - mysql

Question

I have the following query which works as expected.
SELECT T.*, #curRank := #curRank + 1 AS rank
FROM ( SELECT e.guid,
e.name,
(SELECT COUNT(ev.event_vote_id)
FROM event_vote ev
WHERE ev.event_uid = s.guid) AS votes
FROM event e
) as T
CROSS JOIN (SELECT #curRank := 0) r
ORDER BY votes DESC
It returns the guid, name, vote count and rank of all events.
However I want to make it specific to a certain user by linking the user_event table using something like the following:
JOIN user_event ON t.guid = ue.event_uid
WHERE ue.user_uid = 'abc123'
However i'm unsure on where to put this or if this.
I have the following query as a start but it returns exactly the opposite to expected i.e. every event not belonging to the user.
SELECT t.*
FROM user_event ue
JOIN ( SELECT e.guid,
e.name,
e.ownerId,
e.thumbnailSrc,
#curRank := #curRank + 1 AS rank,
( SELECT COUNT(ev.event_vote_id)
FROM event_vote ev
WHERE ev.event_uid = e.guid) AS votes
FROM event e, (SELECT #curRank := 0) r
) AS t
ON t.guid = ue.event_uid
WHERE ue.user_uid = 'abc123'
ORDER BY rank ASC
expected results
list of all of the events:
guid | name | votes | rank
def test2 2 1 (user1)
abc test1 1 2 (user2)
ghi test3 0 3 (user1)
jkl test4 0 4 (user3)
what the query should return for user 1 (user1 guid being abc123)
guid | name | votes | rank
def test2 2 1
ghi test3 0 3

Let's forget about rank for a moment, if you want only event from one specific user you do:
SELECT e.*, ue.*, ( ... ) as votes
FROM event e
JOIN user_event ue
ON e.guid = ue.event_uid
WHERE ue.user_uid = 'abc123'
And over that result you can do ranking.
SELECT T.*, #curRank := #curRank + 1 AS rank
FROM ( ... previous query ... ) as T
CROSS JOIN (SELECT #curRank := 0) r
ORDER BY votes DESC
EDIT:
to filter for a single user you need create another subquery.
calculate votes
calculate ranks
filter user
So query become:
SELECT *
FROM ( SELECT T.*, #curRank := #curRank + 1 AS rank
FROM ( SELECT e.*, ue.*, ( ... ) as votes
FROM event e
JOIN user_event ue
ON e.guid = ue.event_uid ) as T
CROSS JOIN (SELECT #curRank := 0) r
ORDER BY votes DESC
) as ranked_result
WHERE ranked_result.user_uid = 'abc123'
