UPDATE стол со специфическим условием

Question

У меня есть 2 стола - products и product_categories.

Эти таблицы ПРИСОЕДИНЯЙТЕСЬ НА products. product_id = product_categories. product_id.

Я хочу ОБНОВИТЬ поле published в таблице products которые имеют состояние product_categories.product_categories = 100.

Answer 1

Попробуйте

UPDATE bjvui_virtuemart_products as prod 
    INNER JOIN bjvui_virtuemart_product_categories as cat 
    ON prod.virtuemart_product_id =cat.virtuemart_product_id 
SET prod.published ={value} 
WHERE cat.virtuemart_category_id=100 

Answer 2

Использование UPDATE с JOIN

UPDATE TABLEA a 
JOIN TABLEB b ON a.join_colA = b.join_colB 
SET a.columnToUpdate = [something] 
WHERE a.someColumn = [some_value] 

В вашем случае

UPDATE bjvui_virtuemart_products AS p 
INNER JOIN bjvui_virtuemart_product_categories AS c ON 
p.virtuemart_product_id = c.virtuemart_product_id 
SET p.published = "your_value" 
WHERE c.virtuemart_category_id = 100;
