根據用戶在MYSQL中選擇的選項獲取產品

Question

我希望產品具有IN子句中的所有選項。這是我的SQL：

SELECT 
    p.title, p.price FROM products AS p, product_options AS po 
WHERE 
    p.product_id = po.product_id 
AND 
    po.product_option_id IN (5,1,38,39) 
GROUP BY 
    p.product_id; 

Answer 1

如果你想返回具有所有這些選項的結果，那麼你可以使用：

SELECT p.title, p.price 
FROM products AS p 
INNER JOIN product_options AS po 
    ON p.product_id = po.product_id 
WHERE po.product_option_id IN (5,1,38,39) 
GROUP BY p.product_id 
HAVING COUNT(DISTINCT po.product_option_id) = 4;
