如何在 Laravel-5 中构建子查询 [重复]

Question

如何使用 Laravel-5 构建以下 MySQL 查询？

select orders.*, oi.items from orders 
inner join (select order_id, group_concat(item_name SEPARATOR ', ') as items 
from orders_items group by order_id) as oi on oi.order_id = orders.id;

建议的link 没有解决我的问题，但我确实找到了解决方案，并将在下面发布给其他人。

Answer 1

$order  = $order->select('orders.*', 'oi.items');
$order->join(DB::raw('(select order_id, group_concat(item_name SEPARATOR ",") as items from orders_items group by order_id) as oi'), function($join)
{
    $join->on('oi.order_id', '=', 'orders.id');
});
$order->whereRaw('find_in_set ("'.$value.'", oi.items)');

$rows = $order->get();
