How to show multiple results in single columns whith subquery - mysql

Question

I have orders table where i show information about order number, products, and customer.
I need to show list of product names and their qty in column products separated or in new row like below in table:
Expected result
id | order_number | customer | address | total | products
------------------------------------------------------------------------------------
1 | OR00123 | Tom Helks | Test 221 | 1233,2 | 1x iphone
| 2x samsung
| 3x someproduct
Order table
id | order_number | customer_id | total | status_id
------------------------------------------------------------------------------------
1 | OR00123 | 1 | 1233,2 | 1
OrderProducts table
id | order_id | product_id | qty |
------------------------------------------------------
1 | 1 | 5 | 1 |
2 | 1 | 2 | 2 |
3 | 1 | 6 | 3 |
Product table
id | name | price
----------------------------------------
5 | iphone | 1231
2 | samsung | 2322
6 | someproduct | 432
What i try.
I get above expected result but only dont do subquery for listing products and qty for order.
SELECT
order.number,
customer.name,
customer.adress,
SUM(order_products.qty * product.price) as total,
# subquery here
(
SELECT p.name FROM products p WHERE order_products.product_id = p.id
) as products
FROM.orders as order
INNER JOIN customer on customer.customer_id= customer.id
INNER JOIN order_products on order.id = order_products.order_id
ORDER BY dok.created_at;
My imagination stopped and I believe that the problem is in the sub-query, but I can't see it at the moment.
Thanks

You need to join all tables and GROUP BY the unique values.
The GROUP_CONCAT has to be used with then CONCAT of the wanted values
CREATE TABLE orders
(`id` int, `order_number` varchar(7), `customer_id` int, `total` varchar(6), `status_id` int)
;
INSERT INTO orders
(`id`, `order_number`, `customer_id`, `total`, `status_id`)
VALUES
(1, 'OR00123', 1, '1233,2', 1)
;
CREATE TABLE orders_product
(`id` int, `order_id` int, `product_id` int, `qty` int)
;
INSERT INTO orders_product
(`id`, `order_id`, `product_id`, `qty`)
VALUES
(1, 1, 5, 1),
(2, 1, 2, 2),
(3, 1, 6, 3)

INSERT INTO product

SELECT
order_number, `customer_id`, `total`,GROUP_CONCAT(CONCAT( op.`qty`,'x ',p.`name`) SEPARATOR ' ') products
FROM orders o
JOIN orders_product op ON o.`id` = op.`order_id`
JOIN product p ON op.`product_id` = p.`id`
GROUP BY order_number, `customer_id`, `total`
order_number
customer_id
total
products
OR00123

1233,2
