如何将现有数据与新数据合并?

方法1::在这里,我编写了将预订座位数据插入数据库的代码

问题::预订新座位时,它将创建新行,因此我得到重复的行,因此尝试了方法2

方法1代码:

$booking = new Bookings();
        $booking->users_id = 4;
        $booking->schedules_id = $schedules_id;
        $booking->buses_id = $buses_id;
        $booking->routes_id = $routes_id;
        $booking->seat = implode(',', $seat);
        $booking->price = $request->price;
        $booking->profile = 'pending';

方法2:这里检查schedules_id等于存在的schedules_id,然后更新座位和其他数据

问题:插入新数据以更新旧数据

方法2代码:

$booking = Bookings::updateOrCreate(
    ['schedules_id' => $schedules_id], // match the row based on this array
    [ // update this columns
        'buses_id' => $buses_id,
        'routes_id' => $routes_id,
        'seat' => json_encode($seat),
        'price' => $request->price,
        'profile' => 'pending',
    ]

);

//我不知道这在逻辑上是正确的还是错误的

我的想法:在这里,我要检索旧数据并将其存储到一个变量中,然后将旧数据和新数据合并到一列中

问题:出现错误。

我的想法代码:

$extSeat = DB::table('bookings')->select('seat')->get();
        $booking = Bookings::updateOrCreate(
           ['schedules_id' => $schedules_id],
           [ // update this columns
              'buses_id' => $buses_id,
              'routes_id' => $routes_id,
              'seat' => implode(",", array_merge($seat,$extSeat)),
              'price' => $request->price,
              'profile' => 'pending',
           ]);

我实际需要什么? :我需要将现有数据与新数据合并而不进行更新。

旧数据看起来像A1,B1
当插入新数据时,例如C1
我需要像这样的数据A1,B1,C1

我希望我解释得足够清楚。感谢您的任何帮助,谢谢。

I don't know this is a correct logic or not but works for me, any other suggestions are welcome.

    $extSeat = DB::table('bookings')->select('seat')->first();
    $extSeat = explode(",", $extSeat->seat);
    $booking = Bookings::updateOrCreate(
       ['schedules_id' => $schedules_id],
       [ // update this columns
          'buses_id' => $buses_id,
          'routes_id' => $routes_id,
          'seat' => implode(",", array_merge($seat,$extSeat )),
          'price' => $request->price,
          'profile' => 'pending',
       ]);
