Inner join with 3 tables - php

Question

I'm working with PHP and PDO, and I need to recolect information joining 3 tables:
photos
albums
album_photos
The table have the following structure:
photos:
photo_id (int)
path (varchar)
nick (varchar)
date (timestamp)
albums
album_id (int)
album_name (varchar)
nick (varchar)
date (timestamp)
album_photos
album_id (int)
photo_id (int)
nick (varchar)
date (timestamp)
So, I want to show all the albums with a max of 5 photos for each one, where the user nick is 'owner'.
To be shown as follows:
album_name_1:
[photo_1]
[photo_2]
[photo_3]
[photo_4]
[photo_5]
album_name_2:
[photo_1]
[photo_2]
[photo_3]
[photo_4]
[photo_5]
I only know that something like this can be made with INNER JOIN, but I can't found how I can make it with 3 tables.
There examples or other help that I can get to do this?

Answer 1

SELECT a.*, c.date
FROM Album a
INNER JOIN Album_Photo b
ON a.Album_ID = b.Album_ID
INNER JOIN Photo c
ON b.Photo_ID = c.Photo_ID
WHERE c.Nick = 'owner' AND
(
SELECT COUNT(*)
FROM album_photo d
WHERE b.album_id = d.album_id AND
d.nick = 'owner' AND
b.date >= d.date
) <= 2 // <<== change this value to 5

I think this can be resolved using Stored Procedures. Using variables and loops, you can retrieve the records you desire. Getting only a maximum of 5 records from an album is quite challenging when you only use the basic SQL commands. Sometimes, you cannot derive the right records. I suggest you use Stored Proc. :)

Answer 3

Try like
"SELECT albums.*,photos.id,photos.path,photo_date as Pht_date
FROM albums
JOIN album_photos
ON album_photos.album_id = albums.album_id
JOIN photos
ON photos.photos_id = album_photos_id
"
But you cont give individual limit for photos where it involved in "JOIN" orelse you need to give individually like
$album_ids = "SELECT album_id FROM albums";
then for the photos you need to write query liks
"SELECT photos.* FROM photos
WHERE album_photos.album_id in (".$album_ids.") AND album_photos.nick = 'owner'
JOIN album_photos
ON album_photos.photo_id = photos.photos_id
LIMIT 0,10
