如何实现多列相同id分组？- Laravel

use Illuminate\Database\Eloquent\Model;

class YourModel extends Model
{
    public function groupById()
    {
        return $this->select('id', 'column1', 'column2')
            ->groupBy('id')
            ->get();
    }
}

use Illuminate\Support\Facades\DB;

public function groupById()
{
    return DB::table('your_table')
        ->select('id', 'column1', 'column2')
        ->groupBy('id')
        ->get();
}
