Question

SELECT k.attribute_title, GROUP_CONCAT(d.attribute_value)
FROM  current_product_attributes AS k INNER JOIN 
      current_product_attribute_values as d
      ON k.attribute_id = d.attribute_id AND k.attribute_uid = d.attribute_uid
WHERE d.product_id='28'
GROUP BY k.attribute_title

It works, but I need to convert it to laravel eloquent. I tried this code:

$final=DB::select(`k.attribute_title`, `GROUP_CONCAT(d.attribute_value)`)
   ->from(`current_product_attributes AS k`)
   ->join(`current_product_attribute_values  as d `,function($join){
       $join->on(`k.attribute_id = d.attribute_id AND k.attribute_uid = d.attribute_uid`);
   })

    ->where(`d.product_id=$product_data->id`)
    ->groupBy(`k.attribute_title`)->get();


dd($final);

But I have this error:

Argument 1 passed to Illuminate\Database\Connection::prepareBindings() must be of the type array, null given

您可以通过LARAVEL Orator进行此操作，它将原始查询转换为架构生成器查询，但是很遗憾，其在线工具的站点已关闭，因此请重试，然后提出问题
