Question

So I have 2 tables … Products and Images

Products 
---------
id
value1
value2
value3
etc..

Images
---------
id
productId
imageName

The image table will have more than one image per product, so when I run this query:
(the != 0 is because some images don’t have a productId so I want to exclude them, not sure if there is a better way to handle that, or if I even need to include that)

select p.*, i.imageName 
from products p, images i 
where p.id = i.productId and i.productId != 0 

I get the results, but it gives me multiple entries and I just want one result per product and i want it to pull up THE IMAGE THAT WAS ADDED FIRST (so the oldest one) …

Currently the results look like this —

id : 1
imagename: name1.jpg

id : 2
imagename: name5.jpg

id: 2
imagename: name6.jpg

id: 2
imagename: name7.jpg

id: 3
imagename:  name3.jpg

etc... etc... 

I want it to look like this …

id: 1
imagename: name1.jpg

id: 2
imagename: name5.jpg

id: 3
imagename: name 3.jpg

Does this makes sense? Can anyone help me figure out my problem?

Something like this would work, although you will have to check it for typos.

SELECT p.*,
       (SELECT i.imageName
          FROM images
         WHERE i.productId = p.id
        ORDER BY i.date_created ASC
         LIMIT 1)
          AS imageName
  FROM products p
