SQL Server Not Returning Data

Hi,

I have a model that has a simple query. Here's the code:

PHP Code:

$this->db->select("*")
 ->from("vmb_TempsAndTolerances")
 ->where("idgrades", $idgrade)
 ->where("idtypes", $idtype);
 
 $query = $this->db->get();
 $result_array = $query->result_array; 


I have profile turned on and this is the query that is generated by this:

Code:

SELECT *
FROM vmb_TempsAndTolerances
WHERE idgrades =  'C19B5EC2-FBCB-4761-9ACE-43297F0876B7'
AND idtypes =  'BFB30716-EA84-4E34-9A81-1A07EAF37AD5'  

When I copy this into SQL Server Management Studio, I get information returned. Yet, $result_array is coming back empty.

I var_dumped both $query and $result_array and here is what I get from that.

Code:

object(CI_DB_sqlsrv_result)[16]
 public 'conn_id' => resource(29, SQL Server Connection)
 public 'result_id' => resource(39, SQL Server Statement)
 public 'result_array' =>
   array (size=0)
     empty
 public 'result_object' =>
   array (size=0)
     empty
 public 'custom_result_object' =>
   array (size=0)
     empty
 public 'current_row' => int 0
 public 'num_rows' => int 4
 public 'row_data' => null

array (size=0)
 empty

No errors are returned. I have many other queries that work just fine.

Any ideas at this point are appreciated.

Thanks
