将两个字段串联为别名laravel

Answer 1

此处使用过的raw方法laravel和mysql concat方法

DB::raw("CONCAT(`users`.`first_name`,`users`.`last_name`) as full_name")

尝试

$data = DB::table('tables')
    ->select('orders.order_id', DB::raw("CONCAT(`users`.`first_name`,`users`.`last_name`) as full_name"))
    ->leftJoin('lists', 'lists.order_id', '=', 'orders.order_id')
    ->leftJoin('users', 'users.user_id', '=', 'lists.user_id')
    ->where('users.type', '=', 'admin')->get();

dd($data);
