尝试选择MIN（*）最低的行中的所有字段

Question

我在尝试选择同一行中的最低价格和唯一网址时遇到问题，此时它正在从第一行获取unique_url。

SELECT 
  MIN( price ), `unique_url` 
FROM `product_price` 
WHERE `barcode` = '" . $product_barcode . "' 
  AND `active`  = '1' 
GROUP BY `user_id` 
ORDER BY `price` ASC 
LIMIT 1

帮助！

Answer 1

试试这个

SELECT MIN( price ) as mPrice, `unique_url` 
FROM `product_price` 
WHERE `barcode` = '" . $product_barcode . "' AND `active` = '1'
GROUP BY `user_id` 
ORDER BY mPrice ASC 
LIMIT 1
