我想同时从不同字段的2个不同表中获取两个不同的值

Question

我有2个表名为p_order和p_customer。

我必须从相应的字段中获取P_order_no和P_customer_name的值

<?php
      $wherecat = "`p_order_status` = 'active'";
      $catsql =$general->GetRows('*' ,'p_order' ,$wherecat);
      $catRes = mysql_num_rows($catsql);
       <p><muted></muted><br/>
          <a href="#">customer name =</a>order no =<br/>
       </p>
 ?>

Answer 1

试试这个MySQL查询： -

select P_order_no, P_customer_name from p_customer 
inner join p_order on 
(P_customer_id = P_order_customer_id && p_order_status = 'active')

Answer 2

尝试此Illuminate\Database\Eloquent\Collection查询： -

Answer 3

要从两个表中检索值，您必须对其使用操作。对于实现连接，至少需要一个公共列。

select p_order.P_order_no, p_customer.P_customer_name from p_customer join p_order on  p_customer.customer_id = p_order.customer_id
