Question

我正在使用OpenCart，我正在尝试更改此查询。我需要更改它以便它返回去年（从现在起1年）的记录，这是我的查询

$query = $this->db->query("SELECT count(*) AS total, channel FROM `" . DB_PREFIX . "order` WHERE customer_id = '" . (int)$customer_id . "' && order_status_id IN(" . implode(",", $implode) . ") AND YEAR(date_added) = YEAR(CURDATE()) GROUP BY channel");

我尝试将其更改为此，但它的工作正在进行中：

$query = $this->db->query("SELECT count(*) AS total, channel FROM `" . DB_PREFIX . "order` WHERE customer_id = '" . (int)$customer_id . "' && order_status_id IN(" . implode(",", $implode) . ") AND date_added BETWEEN CURDATE() - INTERVAL 1 year AND CURDATE()) GROUP BY channel");

Answer 1

之前，请考虑清理输入数据以保护您的查询免受SQL注入。 Here您可以找到有关此主题的一些内容。

基于this answer，我们可以使您的PHP代码适应以下内容：

$query = $this->db->query("SELECT count(*) AS total, channel 
               FROM `" . DB_PREFIX . "order` 
               WHERE customer_id = '" . (int)$customer_id . "' 
                 AND order_status_id IN(" . implode(",", $implode) . ")
                 AND date_added >= DATE_SUB(NOW(),INTERVAL 1 YEAR)
               GROUP BY channel");

Answer 2

计算去年时语法错误。

您可以使用DATE_SUB。

$query = $this->db->query("SELECT count(*) AS total, channel FROM `" . DB_PREFIX . "order` WHERE customer_id = '" . (int)$customer_id . "' && order_status_id IN(" . implode(",", $implode) . ") AND date_added BETWEEN DATE_SUB(CURDATE(), INTERVAL 1 YEAR) AND CURDATE()) GROUP BY channel");

尝试添加日期范围以进行查询
