php - 如果所有产品都有库存显示或隐藏

Question

我有一份订单上的产品 list ，我想检查这些代码是否有库存。如果我不需要隐藏订单，我可以显示订单上的所有代码。

我有两张 table 。一个是客户订单的产品，一个是商店有货的产品。

我希望此 MySql 连接仅显示我拥有所有产品的订单。如果我没有所有产品，请在列表中隐藏订单。

PHP

<?php while($row = $sql->fetch_array()){?>
    <tr id="row<?php echo $row['id'];?>" style="height:20px">
        <td><?php echo $row['id_comanda']; ?></td>
        <td><?php echo $row['nume_produs']; ?></td>
        <td><?php echo $row['qty']; ?></td>
        <td><?php echo $row['stoc']; ?></td>
    </tr>
<?php } $DBcon->close();?>

MySql

SELECT c.id_comanda
    ,c.nume_produs
    ,c.qty
    ,s.sku
    ,SUM(s.stoc) as stoc
    FROM comenzi_tel_prod c
INNER JOIN stocuri_mentor s ON c.nume_produs = s.sku AND s.stoc >= c.qty
GROUP BY c.nume_produs


OR 

SELECT c.*
    ,s.*
    ,SUM(stoc) AS stoc
FROM comenzi_tel_prod c
INNER JOIN stocuri_mentor s ON c.nume_produs = s.sku
    AND stoc >= c.qty
GROUP BY c.id_comanda

Answer 1

试试这个

 `SELECT c.*
      ,s.*
      ,count(c.id) as instock_count
      ,totals.orders_total

  FROM comenzi_tel_prod c
  INNER JOIN (SELECT *, sum(stoc) as stoc_sum
                FROM stocuri_mentor GROUP BY 
                 sku ) s
     ON c.nume_produs = s.sku
  INNER JOIN (SELECT count(id) as orders_total, id_comanda 
               FROM comenzi_tel_prod 
                GROUP BY id_comanda ) totals
     ON totals.id_comanda = c.id_comanda 

  WHERE stoc_sum >= c.qty
  GROUP BY c.id_comanda
  HAVING instock_count = orders_total`
