OCI Lob->Export()

[Botirjon]

Hi !
I need export picture from Oracle BLOB to file. I am trying with this code. but it's not worked ! Whats wrong? Any comments !

<? 
$conn = oci_connect('dbase','login','pasw'); 
$PicId = $_GET['pic_id'];  

$stmt = @OCIParse($conn, "SELECT resbody, resourceid FROM d_resource_body where resourceid=$PicId" ); 

if (!@OCIFetchInto($stmt, &$result, OCI_ASSOC )) 
  print("Picture PicId=$PicId not found in database"); 

Header("Content-type: image/jpeg"); 
$result['RESBODY']->export('/tmp/pc_pics/'.$result['RESOURCEID'].'jpg'); 
OCILogoff($conn ); 
?> 

Thanks
