此代码的工作原理是inn_db从 发送到表ext_db。

但它无法检查 中的数据是否相同或不同inn_db。

所以在 中提出了相同的值inn_db。

我怎样才能添加那个工作？

Laravel-5.4、MySQL、InnoDB。

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use \DB;

class UpdateCustomerController extends Controller
{
    public function db_update()
    {
        $customers = \DB::connection('ext_db')->table('customers')->orderBy('customer_id')->chunk(1000, function ($all){
            foreach ($all as $kunde){
                DB::connection('inn_db')->table('custoemrs')->insert(
                    [$kunde->customer_id
                     $kunde->name,
                     $kunde->email]);
            }
        });
    }
}

最后，经过讨论，我得到了如下代码和连接视图的答案。

感谢@Pramid 和@Badea :)

    $customers = \DB::connection('ext_db')->table('customers')->orderBy('customer_id')->chunk(1000, function ($all){
        foreach ($all as $kunde){
            $existing_kunde = DB::connection('inn_db')->table('customers')->where([
                    ['customer_id', '=', $kunde->customer_id], 
                    ['name', '=',  $kunde->name], 
                    ['email', '=', $kunde->email]
            ])->first();

            if ( ! $existing_kunde) …

如果模型事实如下所示，那么如何在其中使用Trait getData（）？

此代码无效。

<?php

use App\Working;
use App\Traits\Calculate;

...

    $factory->define(App\Working::class, function  (Faker\Generator $faker) {        
       ...    
       $getData = $this->getData();        
       ...     
       return['get_data' => $getData];

    }

错误信息：
