I have the following four tables. My query is working correctly with the exception that I need to have the field 'AUTHORIZED_VIEWER' and 'AUTHORIZED_VIEWER_EMAIL' return all values not just the first one. I believe that this can be done by using GROUP_CONCAT, however, I am not sure exactly how this part should be implemented. Note - when attempting to use GROUP_CONCAT, I had to use the following syntax as it was return a BLOB:
CONVERT(GROUP_CONCAT(authorized_viewer) USING utf8)
Here are the four tables:
users_tbl
+-----+------------------+
|id |email |
+-----+------------------+
|10 | [email protected] |
|8 | [email protected] |
|11 | [email protected] |
|12 | [email protected] |
+-----+------------------+
authorized_viewers_tbl (authorized_viewer linked to id in users_tbl)
+-----+------------+------------------+
|id |lightbox_id |authorized_viewer |
+-----+------------+------------------+
|1 | 50 |11 |
|7 | 50 |8 |
|3 | 31 |11 |
|5 | 30 |8 |
|6 | 30 |11 |
|8 | 16 |11 |
|9 | 16 |10 |
|10 | 5 |10 |
|11 | 5 |11 |
+-----+------------+------------------+
lightboxes_tbl
+-----+------------------+---------------+
|id |lightbox_name |author |
+-----+------------------+---------------+
|5 | Test Lightbox #1 |[email protected] |

Here's the query that I am currently using:
SELECT lb.id,
lb.lightbox_name,
lb.author,
avt.authorized_viewer,
u.email AS authorized_viewer_email,
COUNT(lba.lightbox_id) total_assets
FROM lightboxes_tbl lb
LEFT JOIN lightbox_assets_tbl lba ON lb.id = lba.lightbox_id
LEFT JOIN authorized_viewers_tbl avt ON avt.lightbox_id = lb.id
LEFT JOIN users_tbl u ON u.id = avt.authorized_viewer
WHERE lb.author = '[email protected]'
OR avt.authorized_viewer =
(SELECT id
FROM users_tbl
WHERE email = '[email protected]')
GROUP BY lb.id
ORDER BY lb.lightbox_name ASC
Thanks!
[EDIT] Expected results based upon SQL Fiddle:
+-------+----------------+--------------+-------------------+--------------------------+--------------+
|id |lightbox_name |author |authorized_viewer | email | total_assets |
+-------+----------------+--------------+-------------------+--------------------------+--------------+
|5 |Test Lightbox#1 |[email protected] |10,11 |[email protected],[email protected] |0 |
|16 |Test Lightbox#2 |[email protected] |10,11 |[email protected],[email protected] |1 |
|30 |Test Lightbox#3 |[email protected] |11,8 |[email protected],[email protected] |1 |
+-------+-------------+-----------------+-------------------+--------------------------+--------------+
There is a cleaner way of doing this but I haven't had the time to think it though yet.
A fun question never the less thanks for sharing and hope we helped!
group_concat to avt.authorized_viewer and u.emaildistinct to the group_concat to only pull back Unique values as requested.group by for each of the non-aggregated values.group_concat to work as desired..
SELECT lb.id,
lb.lightbox_name,
lb.author,
group_concat(distinct avt.authorized_viewer) a,
group_concat(distinct u.email) b,
COUNT(distinct lba.id) total_assets
FROM lightboxes_tbl lb
LEFT JOIN lightbox_assets_tbl lba ON lb.id = lba.lightbox_id
LEFT JOIN authorized_viewers_tbl avt ON avt.lightbox_id = lb.id
LEFT JOIN users_tbl u ON u.id = avt.authorized_viewer
where lb.author = '[email protected]'
or
lb.id in (Select lightbox_ID
from authorized_Viewers_tbl X
INNER JOIN users_Tbl U on U.ID = X.authorized_Viewer
WHERE email = '[email protected]')
GROUP BY lb.id, lb.lightbox_name, lb.author
ORDER BY lb.lightbox_name ASC
