Question

我想通过用户首先使用查询生成器在“订单”表中输入所选ID来检索user_detail表中的全名列

在订单表中看起来像这样

 +"id": 1
  +"order_detail_id": 115
  +"user_id": 3
  +"status": "pending"
  +"updated_at": "2019-11-22 17:53:56"
  +"created_at": "2019-11-22 15:44:28"

在表user_detail中，它看起来像这样

 +"id": 3
  +"full_name": michael jackson
  +"address": "bla bla bla"
  +"updated_at": "2019-11-22 17:53:56"
  +"created_at": "2019-11-22 15:44:28"

我想如果用户输入id 1，它将输出类似

            "id": 1,
            "order_detail_id": 115,
            "user_id": 3,
            "full_name": "michael jackson",
            "address" : "bla bla bla" 
            "status": "pending"

我尝试使用此代码，但仍然出现错误

 $cekclient = DB::table('order')
                                ->where('id',$request->id)
                                ->join('user', 'user.id', '=', 'order.user_id')
                                ->select('order.*','user.name','user.address',)
                                ->get();

            dd($cekclient);

尝试此代码。请给表别名并在选择和联接中使用它们。

$cekclient  = DB::table('order as or')
            ->select('or*','u.name','u.address') // here you can add column names which you need in output
            ->leftJoin('user as u', 'u.id', '=', 'or.user_id')
            ->where('or.id',$request->id) // here if you need data by id of user then use u.id in where insead of or.id
            ->get();

我想通过选择用户在Laravel中输入的ID来合并两个表
