如何从 SQL 列和表中显示以特定价值出售的商品数量
问题描述 投票：0回答：1
我对 SQL 的了解很少。
我想显示从我的 SQL 数据库中销售的软件包数量，以获取 CodeIgniter 上不同 ID（软件包 ID）的特定表值。
当我尝试输入一些编码时，它显示所有包裹的销售包裹数量相同。
表：付款
这是我的代码：
$this->db->where('payment_status', 'succeeded');
$this->db->where('item_price', '50000.00');
$succeededpayment = $this->db->get('payments');
我只想显示每个不同 ID（包裹）的 payment_status 已成功，表（付款）中的 item_price = 50000，但它显示所有包裹销售的包裹数量相同。
显示已售包裹数量的代码：
<?php echo $succeededpayment->num_rows(); ?>
这是结果；
上图显示已售出22包（右上角）。
事实：套餐 1 有 21 次销售，套餐 2 有 1 次销售。

现在，对于具有硬编码 ID 的单个测验，您只能获得一次结果，然后为所有测验显示相同的结果。您希望使用不同的
quiz_id为此，您需要移动此查询块...
$this->db->where('payment_status', 'succeeded');
$this->db->where('item_price', '50000.00');
$this->db->where('quiz_id', 1);
//$this->db->where('quiz_id', 116);
$succeededpayment = $this->db->get('payments');
... 到 foreach 循环内部，以便为每个测验执行它。然后将
$this->db->where('quiz_id', 1);$this->db->where('quiz_id', $quiz_id);视图如下所示：
<?php
$quiz_running = 'no_quiz_start';
$session_quiz_id = NULL;
$gradients = array();
$gradients[] = 'mask gradient-vue';

if($session_quiz_data && $session_quiz_question_data)
{

}
