How to make a “distinct” join with MySQL

Question

I have two MySQL tables (product and price history) that I would like to join:

Product table:

Id = int
Name = varchar
Manufacturer = varchar         


        

Answer 1

SELECT n.product_id, 
       n.product_name,
       n.product_articul,
       n.product_price,
       n.product_discount,
       n.product_description, 
       n.product_care,
       (SELECT photo_name FROM siamm_product_photos WHERE product_id = n.product_id LIMIT 1) AS photo_name
FROM siamm_product as n;
