CI 3.0 + SQl Server

i'm kinda new in CodeIgniter, i'm trying to develop application that will have SQL server as the database.

my database.config :

PHP Code:

$db['default'] = array(
 'dsn' => '',
 'hostname' => '127.0.0.1',
        'port' => '1433',
 'username' => 'dap',
 'password' => '******',       
 'database' => 'Dap_Db',
 'dbdriver' => 'sqlsrv',
 'dbprefix' => '',
 'pconnect' => FALSE,
 'db_debug' => FALSE,
 'cache_on' => FALSE,
 'cachedir' => '',
 'char_set' => 'utf8',
 'dbcollat' => 'utf8_general_ci',
 'swap_pre' => '',
 'encrypt' => FALSE,
 'compress' => FALSE,
 'stricton' => FALSE,
 'failover' => array(),
 'save_queries' => TRUE

); 


PHP Code:

my model : 

class Sql_model extends CI_Model

{
    public function __construct() {
        parent::__construct();
    }
    
    function getAll()
    {
        $query = $this->db->get('Customers');
        return $query->result();
    }
} 


PHP Code:

my controller :
class Test extends CI_Controller

{
    
    public function check()
    {
        $this->load->model('Sql_model');
        $arr = $this->Sql_model->getAll();
       // $this->output->enable_profiler(TRUE);
        echo json_encode($arr);
    }
} 


and also i dowload Microsoft Drivers 3.0 for PHP for SQL Server ver. 3.0  5.4  and  i'm using SQL server 2005.

but in the end i got this error :

Code:

A PHP Error was encountered

Severity: Warning
Message: sqlsrv_query() expects parameter 1 to be resource, boolean given
Filename: sqlsrv/sqlsrv_driver.php
Line Number: 199

The line number referenced in the error message doesn't line up with a call to sqlsrv_query() in the CI 3 releases. This makes me think that something in one or more of the files in your database library has been modified and may be the cause of the problem.

sqlsrv_query() is usually only called in _execute(), which is not usually used without checking the connection. However, there does appear to be one method in sqlsrv_driver (db_select()) which calls _execute() without checking the connection first, so there may be some potential for this to occur in an unmodified driver.
