Laravel 5.2同时使用两个不同的数据库连接（sqlsrv + mysql）

Question

I would like to do something like this when i use a model

class DB extends Model {

Protected $table = "mssql_table";
}

DB::useConnection("mssql")->All();

As far as configuration goes i've found out that I can add it myself in app/config/database.php

And so I did.

So now i've got this in my connetions:

'mssql' => [
    'driver' => 'sqlsrv',
    'host' => env('DB_MSSQL_HOST', 'localhost'),
    'port' => env('DB_MSSQL_PORT', '3306'),
    'database' => env('DB_MSSQL_DATABASE', 'forge'),
    'username' => env('DB_MSSQL_USERNAME', 'forge'),
    'password' => env('DB_MSSQL_PASSWORD', ''),
    'charset' => 'utf8',
    'collation' => 'utf8_unicode_ci',
    'prefix' => '',
    'strict' => false,
    'engine' => null,
],

and this to my .env file

DB_MSSQL_HOST=
DB_MSSQL_PORT=
DB_MSSQL_DATABASE=
DB_MSSQL_USERNAME=
DB_MSSQL_PASSWORD=

But what is the next step? google didnt really help me that much, in laravel 4.* you could use db::connection(); but it dosent seem to work anymore

Any ideas?

First, you need to set-up one or more databases in your config (be sure to change values, I just pretty much copied and pasted):

'db1' => [
    'driver' => 'sqlsrv',
    'host' => env('DB_MSSQL_HOST', 'localhost'),
    'port' => env('DB_MSSQL_PORT', '3306'),
    'database' => env('DB_MSSQL_DATABASE', 'forge'),
    'username' => env('DB_MSSQL_USERNAME', 'forge'),
    'password' => env('DB_MSSQL_PASSWORD', ''),
    'charset' => 'utf8',
    'collation' => 'utf8_unicode_ci',
    'prefix' => '',
    'strict' => false,
    'engine' => null,
],

'db2' => [
    'driver' => 'sqlsrv',
    'host' => env('DB_MSSQL_HOST', 'localhost'),
    'port' => env('DB_MSSQL_PORT', '3306'),
    'database' => env('DB_MSSQL_DATABASE', 'forge'),
    'username' => env('DB_MSSQL_USERNAME', 'forge'),
    'password' => env('DB_MSSQL_PASSWORD', ''),
    'charset' => 'utf8',
    'collation' => 'utf8_unicode_ci',
    'prefix' => '',
    'strict' => false,
    'engine' => null,
],

Then of course, you're going to need to create some migration schema for the newly added database (you need tables, etc.):

Schema::connection('db2')->create('table_name', function($table)
{
    $table->increments('id');
    ...
});

Now in your Eloquent model, you can define what database you want to use like so:

class ModelName extends Eloquent {

    protected $connection = 'db2';

}
