I have a WMS layer define like this: createWmsLayer('ecoles', '.../cgi-bin/mapserv.exe?map=MYMAP',{layers: 'ecoles', transparent: "true", format:"image/gif", SEMCDC:thisCDC, RSS: thisRSS, ORDRE: thisOrdre},{isBaseLayer: false, visibility: false,singleTile:true,transitionEffect: 'resize'}); I have 3 variables: SEMCDC, RSS, ORDRE In the mapfile I use this statement FILTER "semcdc in (%SEMCDC%) and rss in (%RSS%) and ordre in (%ORDRE%)" The getMap request is succesfull. Here is the request /cgi-bin/mapserv.exe?map=MYMAP service=WMS&version=1.1.0&request=GetFeatureInfo&layers=ecoles&query_layers=ecoles&styles=&bbox=-8820221.560815%2C5721770.182129%2C-7587445.168853%2C6361395.234705&srs=EPSG%3A900913&feature_count=3000&x=272&y=457&height=523&width=1008&info_format=text%2Fhtml Here is the response <?xml version='1.0' encoding="ISO-8859-1" standalone="no" ?> <!DOCTYPE ServiceExceptionReport SYSTEM " http://schemas.opengis.net/wms/1.1.0/exception_1_1_0.dtd"> <ServiceExceptionReport version="1.1.0"> <ServiceException> prepare_database(): Query error.
