Помощь в создании запроса sql

Recommended Posts

Сделал такой список:
Не получается сделать запрос к другой таблице(notify_when_arrives) чтобы подсчитать количество ожидающих клиентов
В той таблице есть колонка с id товаров - они повторяются (к примеру 5 раз 63, 2 раза 66 и тд)
Почему то колонку "Ожидают" считает не правильно, хотя делал по аналогии с колонкой "Куплено"


language_id в таблице notify_when_arrives - всегда 1

Запрос к таблицам

    public function getprr($data = array()) {

        $sql  = "SELECT p.product_id, ";
        $sql .= "pd.name AS product_name, ";
        $sql .= "SUM(op.quantity) AS purchased, "; // подсчет купленных товаров
        $sql .= "SUM(nwa.language_id) AS expecting, "; // подсчет ожиданий
        $sql .= "p.viewed, ";
        $sql .= "p.quantity AS product_quantity, ";
        $sql .= "p.orderednoopt ";
	$sql .= "FROM ".DB_PREFIX."product p ";
        $sql .= "LEFT JOIN ".DB_PREFIX."product_description pd ON pd.product_id=p.product_id ";
        $sql .= "LEFT JOIN ".DB_PREFIX."order_product op ON op.product_id=p.product_id ";
        $sql .= "LEFT JOIN ".DB_PREFIX."notify_when_arrives nwa ON nwa.product_id=p.product_id ";
        $sql .= "WHERE p.status = '1' ";
        $sort_data = array(
            $sql .= " GROUP BY p.product_id";
			if (isset($data['sort']) && in_array($data['sort'], $sort_data)) {
				$sql .= " ORDER BY " . $data['sort'];
			} else {
				$sql .= " ORDER BY pd.name";
			if (isset($data['order']) && ($data['order'] == 'DESC')) {
				$sql .= " DESC";
			} else {
				$sql .= " ASC";
        $query = $this->db->query($sql);
        return $query->rows;

Код из php

$prrs = $this->model_report_roptions->getprr($data);
foreach ($prrs as $prr) {
	$this->data['prods'][] = array(
                'product_id'        => $prr['product_id'],
                'product_name'      => $prr['product_name'],
                'purchased'         => $prr['purchased'],
                'views'             => $prr['viewed'],
                'expecting'         => $prr['expecting'],
                'product_quantity'  => $prr['product_quantity'],
                'orderednoopt'      => $prr['orderednoopt']

Код из tpl

          <?php foreach ($prods as $prod) { ?>
            <td><?php echo $prod['product_id']; ?></td>
            <td><?php echo $prod['product_name']; ?></td>
            <td><?php if (isset($prod['purchased'])) { echo $prod['purchased']; } else { echo 0; } ?></td>
            <td><?php echo $prod['views']; ?></td>
            <td><?php echo $prod['expecting']; ?></td>
            <td><?php echo $prod['product_quantity']; ?></td>
            <td><?php echo $prod['orderednoopt']; ?></td>
          <?php } ?>


Подскажите пожалуйста, что не правильно делаю?

По идее запрос надо такой:

SELECT p.product_id,

(SELECT COUNT(*) FROM notify_when_arrives nwa WHERE nwa.product_id=p.product_id) AS arrives_count,
pd.name AS product_name,

... Дальше всё остальное


LEFT JOIN notify_when_arrives из запроса надо убрать.
