Сортировать по цене и лимиту 3

Question

У меня есть запрос, который дает мне количество продукции по цене. Я попытался отсортировать их с помощью ORDER BY p.price ASC LIMIT, но это не дало мне правильной сортировки. Я также попытался изменить ($query->rows as $product), но не тренировки

Это мой запрос:

$result = array(); 

if ($this->customer->isLogged()) { 
    $customer_group_id = $this->customer->getCustomerGroupId(); 
} else { 
    $customer_group_id = $this->config->get('config_customer_group_id'); 
} 

$query = $this->db->query("SELECT DISTINCT *, 
          pd.name AS name, 
          p.image, m.name AS manufacturer, 
          (SELECT price FROM " . DB_PREFIX . "product_discount pd2 WHERE pd2.product_id = p.product_id AND pd2.customer_group_id = '" . (int)$customer_group_id . "' AND pd2.quantity = '1' AND ((pd2.date_start = '0000-00-00' OR pd2.date_start < NOW()) AND (pd2.date_end = '0000-00-00' OR pd2.date_end > NOW())) ORDER BY pd2.priority ASC, pd2.price ASC LIMIT 1) AS discount, 
          (SELECT price FROM " . DB_PREFIX . "product_special ps WHERE ps.product_id = p.product_id AND ps.customer_group_id = '" . (int)$customer_group_id .

          (SELECT points FROM " . DB_PREFIX . "product_reward pr WHERE pr.product_id = p.product_id AND customer_group_id = '" . (int)$customer_group_id . "') AS reward, (SELECT ss.name FROM " .

return $result;

Answer 1

Я просто попробовал ваш код в точности так, как это, опуская только p.aldoc = '" . $this->db->escape($aldoc_id) . "', так как я не имею, что поле и отлично работает с

ORDER BY p.price ASC LIMIT 3"); 

Ваш текущий окончание, однако, не является. Вы должны сделать это:

p2s.store_id = '" . (int)$this->config->get('config_store_id') . "'); 

Вдвоем должен выглядеть следующим образом:

p2s.store_id = '" . (int)$this->config->get('config_store_id') . "' 
ORDER BY p.price ASC LIMIT 3");
