Question

I have a table that has two columns. One is image_id and one is image_name. Like this

image_id | image_name
--------------------
1        | terrier.jpg
2        | schnauzer.jpg
3        | beagle.jpg

And I have another table like this:

item           |  image_1 | image_2
------------------------------------
Friendly Dogs  |   1      |    2 
Loyal Dogs     |   2      |    3

The first table let’s call images and the second table is dogs.

I tried the following SQL but it didn’t work:

SELECT * FROM dogs INNER JOIN  images ON images.image_id = dogs.image_1 AND INNER JOIN images ON images_image_id = dogs.image_2

But this errors out. I’m missing somethings where I can specify names some kind of alias or something for image_name so it doesn’t overlap in the query.

What I want is an array that has image_1 and image_2 in it rather than image_name.

Can someone help out? Thanks.

I want in the array two arrays or objects:

[item] => Friendly Dogs
[image_1] => terrier.jpg
[image_2] => schnauzer.jpg

and

[item] => Loyal Dogs
[image_1] => schnauzer.jpg
[image_2] => beagle.jpg

You can JOIN a table multiple times:

SELECT d.item AS dog, i1.image_name AS im1, i2.image_name AS im2
FROM dogs AS d JOIN images AS i1 ON (i1.image_id = d.image_1)
               JOIN images AS i2 ON (i2.image_id = d.image_2)
