Happy new year everybody!!

i am using a binary 3.6.3 release of mapserver with php_mapscript.
I am having trouble with the setquery method and integer datas..
I am using tab files
i would like to select the feature where index=3D2 for example

$oLayer =3D $oMapSession->oMap->getLayerByName( $http_form_vars[ =
"layerref" ] );
$query=3D2;
$oLayer->setFilter($query);
=20
  if (@$oLayer->queryByAttributes(MS_SINGLE) =3D=3D MS_SUCCESS)
{=20
......
}
i have used successfully this method with string values ($query=3D'id2') =
but never with integer values..

the log file return me :

[Mon Jan 12 01:36:44 2004] [error] [client 192.168.1.2] PHP Fatal error: =
 MapServer Error in getSymbol(): (169):(147)

Is it better or faster to use integer values or string values to perform =
query, index or expression?

Any suggestion for my problem??

thanks
