MS SQL with Magento

Here is a way to connect mssql database using Magento’s inbuilt models.

<?php

include_once 'app/Mage.php';
Mage::app();

$host = '';//in the format 127.0.0.1:1433 , 1433 is the default port number 
$user = ''; // DB user name 
$pass = ''; // DB password 
$dbname = ''; //DB name 

$db = new Zend_Db_Adapter_Pdo_Mssql(array(
 'host'     => $host, 
 'username' => $user,
 'password' => $pass,
 'dbname'   => $dbname,
'pdoType'  =>  'dblib' )
 );

try{
	$db->getConnection();
}catch(Exception $e)
{
	print_R($e);
}


$sql = '' ; //SQL query goes here
$stmt = $db->query($sql);
$qryResult = $db->fetchOne($sql);
print_r($qryResult);

?>

Hope this is helpful
