Sql update where left join count equal to 3 - mysql

Question

Hi I'm trying to build a sql query where I update the value of a table where the left join of another table is equal to 3.
Example when a vehicle has 3 photos.
The query I've written thus far, it seems to fail with group by though.
UPDATE domain.vehicle_listing AS t0 LEFT OUTER JOIN photo AS t1 ON t0.id = t1.vehicle_listing_id
SET t0.active = 0
WHERE `create_date` >= '2015-5-2'
AND user_profile_id is not null
AND t0.active = 1
GROUP BY t1.vehicle_listing_id
HAVING COUNT(DISTINCT t1.id) = 3
ORDER BY create_date desc;
Vehicle_Listing
id
Photo
id, vehicle_listing_id, photo_url
OneToMany relationship with photo.

Answer 1

You can also use exists
UPDATE vehicle_listing AS t0
SET t0.active = 0
WHERE t0.`create_date` >= '2015-05-02'
AND t0.user_profile_id is not null
AND t0.active = 1
AND EXISTS (
SELECT 1
FROM photo
WHERE vehicle_listing_id=t0.id
GROUP BY vehicle_listing_id
HAVING COUNT(DISTINCT id) = 3
)
Sample data for vehicle_listing
INSERT INTO vehicle_listing
(`id`, `title`, `create_date`, `active`,user_profile_id)
VALUES
(1, 'test', '2015-05-02 00:00:00', 1,1),
(2, 'test1', '2015-05-02 00:00:00', 1,1)
;
Sample data for photo
INSERT INTO photo
(`id`, `vehicle_listing_id`, `photo_url`)
VALUES
(1, 1, 'image.jpg'),
(2, 1, 'image.jpg'),
(3, 1, 'image.jpg'),
(4, 2, 'image.jpg'),
(5, 2, 'image.jpg')
;
Sample Output
id title create_date active user_profile_id
1 test May, 02 2015 00:00:00 0 1
2 test1 May, 02 2015 00:00:00 1 1

Answer 2

It is silly to use a left join for this. You want inner join:
UPDATE cardaddy.vehicle_listing vl INNER JOIN
(SELECT p.vehicle_listing_id, count(*) as cnt
FROM photo p
GROUP BY p.vehicle_listing_id
) p
ON vl.id = p.vehicle_listing_id AND
p.cnt = 3
SET vl.active = 0
WHERE vl.create_date >= '2015-05-02' AND
vl.user_profile_id IS NOT NULL AND
vl.active = 1;
(Assuming that user_profile_id is in vehicle_listing.)

Answer 3

UPDATE cardaddy.vehicle_listing AS t0
LEFT OUTER JOIN (
SELECT vehicle_listing_id, count(1) AS counter
FROM photo
GROUP BY vehicle_listing_id
) AS t1
ON t0.id = t1.vehicle_listing_id
AND t1.counter = 3
SET t0.active = 0
WHERE `create_date` >= '2015-5-2'
AND user_profile_id IS NOT NULL
AND t0.active = 1
AND t1.vehicle_list_is IS NOT NULL
