I am trying to populate select field in ChartsForm.php from db and created a factory, maybe some error in module.config.php it's says.
Catchable fatal error: Argument 1 passed to Charts\Form\ChartsForm::__construct() must be an instance of Charts\Model\PostRepositoryInterface, none given, called in C:\wamp\www\bw\module\Charts\src\Controller\ChartsController.php on line 60 and defined in C:\wamp\www\bw\module\Charts\src\Form\ChartsForm.php on line 24
Help me out please.

Answer 1

Can you be more specific? What type of database?
You have two options: PDO (For all driver) and MySQLy (for MySQL).
Look here for a greater response:
https://stackoverflow.com/a/8255054/6784143
UPDATE:
You can connect your Sql Server with this line code (running good on .php).
resource mssql_connect ([ string $servername [, string $username [, string $password [, bool $new_link = false ]]]] )
You can execute a query with this line code.
mixed sqlsrv_query ( resource $conn , string $sql [, array $params [, array $options ]] )
