连接到Laravel 5中的两个数据库

Question

I can connect the databases in my project created by Laravel 5, but I use this code.

Is there any way to add User::all() before that ->select("select * from users"); ?

public function index(){
    $user = \DB::connection('nombrebd')->select("select * from users");
    $user2 = \DB::connection('nombrebd2')->select("select * from users");
    return $user+$user2;    
}

UPDATE

Sorry for my bad explanation , I need to receive all information about user in two differents databases.

Answer 1

If your intention is to use Eloquent as the base of your query to avoid writing actual SQL statements, you can do the following to get all users from each database:

$user = App::make('App\User')->setConnection('nombrebd')->get();
$user2 = App::make('App\User')->setConnection('nombrebd2')->get();

You can't use User::all() as you'd like, because that initialises a query builder instance and fetches the results all in one go, so there is no way to specify which connection it should use.

Answer 2

You could have two models, and in one of them you can specify an alternate connection:

protected $connection = 'mysql-alt';

Once you query both models, you can even merge them as such:

$users = $user_list_a->merge($user_list_b);

I use this approach when dealing with legacy databases.
