MYSQL Prestashop 1.7 更新價格 multistore

Question

如何為給定產品 ID 和商店 ID 的所有行運行它：

一張表：ps_product_shop

id_product	價格	id_shop
1個	1個	1個
1個	25	3個
2個	2個	1個
2個	50	3個

謝謝

對於一行： UPDATE ps_product_shop SET price=(SELECT price FROM ps_product_shop WHERE id_product = '1' AND id_shop = '1')*25 WHERE (id_product='1') AND (id_shop='3');

我試過了，但它不起作用： UPDATE ps_product_shop SET price=(SELECT price FROM ps_product_shop WHERE id_product = ps_product_shop.id_product AND id_shop = '1')*25 WHERE ps_product_shop.id_product IN (SELECT price FROM ps_product_shop WHERE id_product = ps_product_shop.id_product AND id_shop = '3');

Answer 1

是這樣的嗎？

UPDATE ps_product p, ps_product_shop ps 
SET p.price = p.price*25, ps.price = ps.price*25
WHERE p.id_product = 1 AND ps.id_product = 1 AND ps.id_shop = 2

Answer 2

我已經想通了，也許它會幫助某人：

UPDATE ps_product_shop AS sk SET 
price=(SELECT price FROM ps_product_shop
WHERE id_product = sk.id_product AND id_shop = '1')*27 WHERE (sk.id_shop='3');

對於所有行 sk.id_shop='3'
