Need help with active record

Thanks @CroNiX & @theshiftexchange.

i've found out the problem.
Apparently it's because of the sqlsrv driver i used has been edited.

The edited code:

Code:

function _execute($sql)
{
   $sql = $this->_prep_query($sql);

          //add this part
   if(stripos($sql,'UPDATE') !== FALSE || stripos($sql,'INSERT') !== FALSE) {
            return sqlsrv_query($this->conn_id, $sql, null, array());
       }

   return sqlsrv_query($this->conn_id, $sql, null, array(
  'Scrollable'    => SQLSRV_CURSOR_STATIC,
  'SendStreamParamsAtExec' => true
   ));
}

if that part is remarked, this problem is solved.
But function

Code:

$this->db->affected_rows()

wouldn't work as that part is to fix it.

Is there any solution that can be used so that this problem won't collide each other?

Thanks.
