/**
 * Microsoft SQL Server 2008+ connector class.
 *
 * <h2>Connecting using Windows</h2>
 *
 * If you've got your website running on Windows, it's highly recommended you
 * use Microsoft SQL Server Driver for PHP "sqlsrv".
 *
 * A complete guide to installing a Windows IIS + PHP + SQL Server web stack can be
 * found here: http://doc.silverstripe.org/installation-on-windows-server-manual-iis
 *
 * @see http://sqlsrvphp.codeplex.com/
 *
 * <h2>Connecting using Linux or Mac OS X</h2>
 *
 * The following commands assume you used the default package manager
 * to install PHP with the operating system.
 *
 * Debian, and Ubuntu:
 * <code>apt-get install php5-sybase</code>
 *
 * Fedora, CentOS and RedHat:
 * <code>yum install php-mssql</code>
 *
 * Mac OS X (MacPorts):
 * <code>port install php5-mssql</code>
 *
 * These packages will install the mssql extension for PHP, as well
 * as FreeTDS, which will let you connect to SQL Server.
 *
 * More information available in the SilverStripe developer wiki:
 * @see http://doc.silverstripe.org/modules:mssql
 * @see http://doc.silverstripe.org/installation-on-windows-server-manual-iis
 *
 * References:
 * @see http://freetds.org
