Question

Ok so i have this structure

PRODUCTS

* PRODUCT_ID (primary key)
* PRODUCT_NAME

CATEGORIES

* CATEGORY_ID (primary key)
* CATEGORY_NAME
* CODE

PRODUCT_CATEGORIES_MAP

* PRODUCT_ID (primary key, foreign key to PRODUCTS)
* CATEGORY_ID (primary key, foreign key to CATEGORIES)
* QUANTITY

I am using this query

SELECT * FROM `products`
where id in (
    SELECT `product_id`
    FROM `categorizations`
    WHERE category_id = (
        SELECT id
        FROM `categories`
        where code = 'something'))

this works great but i am just getting a list of products. I need the quantity of each one one in the join table

Answer 1

The table names in your explanation are different from your sample query. I used the ones from your query.

SELECT p.product_id  ,
       p.product_name,
       pc.quantity
FROM   `products` p
       JOIN `categorizations` pc
       ON     p.id = pc.`product_id`
       JOIN `categories` c
       ON     c.id = pc.category_id
WHERE  c.code      = 'something'
