如何獲得一個SQL查詢中內的類別列表的IDS產品68,40,41,55,66的IDS的列表...和製造商的IDS列表210788233 ....和STORE_ID = 1，以避免用PHP foreach循環並避免重複產品id？

Answer 1

SELECT DISTINCT p.product_id FROM products_to_stores p INNER JOIN products_to_categories c ON c.product_id = p.product_id INNER JOIN product_descriptions d ON d.product_id = p.product_id 
WHERE 
manufacturer_id IN (210,788) AND category_id IN (40,44) AND store_id = 1 

Answer 2

SELECT descriptions.product_id FROM product_descriptions AS descriptions 
    INNER JOIN products_to_categories AS category ON category.product_id = descriptions.product_id AND category.category_id IN (/* Your categories */) 
    INNER JOIN products_to_stores AS stores ON stores.product_id = descriptions.product_id AND stores.store_id = 1 
WHERE descriptions.manufacturer_id IN (/* .... */) 
GROUP BY descriptions.product_id
