EDIT-
First you need to download the driver
http://msdn.microsoft.com/en-us/sqlserver/ff657782.aspx
Now go to your XAMPP installation and search for php.dll
It will display correct PHP dll you have.
1) move following files to xampp/php/ext directory.
php_sqlsrv_53_nts_vc9.dll
php_pdo_sqlsrv_53_nts_vc9.dll
2) If you have php5ts.dll then move following files to xampp/php/ext directory.
php_sqlsrv_53_ts_vc9.dll
php_pdo_sqlsrv_53_ts_vc9.dll
above files should be used if your PHP version is compiled with Visual C++ 9.0 . Else following files should be used.
1) If you have php.dll then move following files to xampp/php/ext directory.
php_sqlsrv_53_nts_vc6.dll
php_pdo_sqlsrv_53_nts_vc6.dll
2) If you have php5ts.dll then move following files to xampp/php/ext directory.
php_sqlsrv_53_ts_vc6.dll
php_pdo_sqlsrv_53_ts_vc6.dll
Now we have to load files that we added recently. Open the php ini file and add entry in the area of dynamic extensions as follow.
extension=php_sqlsrv_53_nts_vc9.dll
extension= php_pdo_sqlsrv_53_nts_vc9 .dll
Save the ini files and restart XAMPP
$check= @$CI->load->database($config, TRUE); // ommit the error
if ($check->call_function('error') !== 0) {
// Failed to connect
}
I don't know for sure what you are trying to do but in codeigniter you don't need to initialise database, CI automatically does it for you
so-
$this->load->database();
$db_obj = $this->db->load('SQL_Test',TRUE);
$connected = $db_obj->initialize();
this is not needed.
You just need to load the model and in model start performing queries.
$this->load->database();
In controller you need to load the model like-
$this->load->model('my_model');
then call the model function in which you have written the queries.
$this->my_model->myfunction();
