ERROR
SQLSTATE[42S02]: Base table or view not found: 1146 Table
'database_1.countries' doesn't exist (SQL: select * from countries)
MODEL
class Country extends Model {
use SoftDeletes;
protected $connection = 'mysql_2';
protected $table = 'countries';
protected $fillable = ['...'];
}
CONTROLLER / DEBUGGINB
class CountriesController extends Controller {
public function index(){
// neither works, this
$countries = DB::connection("mysql_2")->select('select * from countries');
// or this
$countries = Country::all();
dd($countries); --> both give ERROR
}

Answer 1

In your database.php file try to change
'mysql_2' => [
'driver' => 'mysql',
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE2', 'database_2'), // THIS IS THE ONE THATS CHANGED
'username' => env('DB_USERNAME', 'root'),
'password' => env('DB_PASSWORD', ''),
.......
],
.ENV FILE
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=database_1
DB_USERNAME=root
DB_PASSWORD=
DB_CONNECTION=mysql_2
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE2=database_2 // We change 'DB_Database' to 'DB_Database2'
DB_USERNAME=root
DB_PASSWORD=

Answer 2

Another process you can try -
.env
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=database_1
DB_USERNAME=root
DB_PASSWORD=
CUSTOM_DATABASE=database_2
CUSTOM_USERNAME=root
CUSTOM_PASSWORD=
database.php
'mysql' => [
'driver' => 'mysql',
'url' => env('DATABASE_URL'),
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
...................................
],
'custom' => [
'driver' => 'mysql',
'url' => env('DATABASE_URL'),
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '3306'),
'database' => env('CUSTOM_DATABASE', 'forge'),
'username' => env('CUSTOM_USERNAME', 'forge'),
'password' => env('CUSTOM_PASSWORD', ''),
..........................................
],
YourModel.php
protected $connection = 'custom';
protected $fillable = [......];
If you use protected $connection in your model then you can use eloquent as usual. If so, then you can run your query like this -
$countries = Country::all();
And in your migration file -
public function up()
{
Schema::connection('custom')->create('your-table-name', function (Blueprint $table){
$table->bigIncrements('id');
...........................
$table->timestamps();
});
}
