Answer 1

If your stored procedure returns multiple outputs, In this case, you can handle this situation by two methods.

1. Goto vendor\laravel\framework\src\Illuminate\Database\Connectors\Connector.php and set PDO::ATTR_EMULATE_PREPARES as true.

It will create problems when you will developing APIs, because of all APIs return numbers as a string when response return in JSON Like: {"status": "1"} but it should be {"status": 1}

2. Add a new connection to a particular situation. You have to handle the above discussed problem for a particular API only not in all APIs. So I suggest choosing option 2nd.

Add connection in the config/database.php use below code into connections

'mysql_procedure' => [
'driver' => 'mysql',
'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', ''),
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => 'sv_',
'prefix_indexes' => true,
'strict' => false,
'engine' => null,
'options' => extension_loaded('pdo_mysql') ? array_filter([
PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),PDO::ATTR_EMULATE_PREPARES => true
]) : [],
],

update details as per your configuration.

$procRslts = DB::connection('mysql_procedure')
->select("CALL user_login(?,?,?,?)", array( $userId ,$password,$success,$firstName ));

I think in this you don't need to pass the last two parameters, you can write logic int procedure to get from the database.

You can get multiple outputs returned by the stored procedure.
