順序按價格和限制3

Question

我有一個查詢，給我一個價格的產品數量的輸出。 我試圖用ORDER BY p.price ASC LIMIT對它們進行排序，但這並沒有給我正確的排序。 我也試圖改變這種（$query->rows as $product），但沒有鍛鍊

這是我的查詢：

$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)$customer_group_id . "' AND ((ps.date_start = '0000-00-00' OR ps.date_start < NOW()) AND (ps.date_end = '0000-00-00' OR ps.date_end > NOW())) ORDER BY ps.priority ASC, ps.price ASC LIMIT 1) AS special, 
          (SELECT points FROM " . DB_PREFIX . "product_reward pr WHERE pr.product_id = p.product_id AND customer_group_id = '" . (int)$customer_group_id . "') AS reward, (SELECT ss.name FROM " .

          (SELECT wcd.unit FROM " . DB_PREFIX . "weight_class_description wcd WHERE p.weight_class_id = wcd.weight_class_id AND wcd.language_id = '" . (int)$this->config->get('config_language_id') .

          (SELECT AVG(rating) AS total FROM " . DB_PREFIX . "review r1 WHERE r1.product_id = p.product_id AND r1.status = '1' GROUP BY r1.product_id) AS rating,

          FROM " . DB_PREFIX . "product p

         // ORDER BY p.price ASC LIMIT 3"); 

foreach ($query->rows as $product){ 
    $result[] = array(
    'product_id'  => $product['product_id'], 
    'name'    => $product['name'],

} 

return $result; 
} 

Answer 1

我只是想你的代碼完全相同，因爲它是唯一的省略，因爲p.aldoc = '" . $this->db->escape($aldoc_id) . "'我沒有那些它可以正常工作

ORDER BY p.price ASC LIMIT 3"); 

但是，您目前的結局並不是。你需要使它：

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

兩個在一起應該是這樣的：

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