You could also use the intersect() method of the GeometryService.

Yes, you will be a lot better off using geometry services.

private function SelectPoints(queryGraphic:Polygon):void
   {
    var query:Query=new Query();
    var queryTask:QueryTask = new QueryTask();
    queryTask.url = "http://****/sdgis/rest/services/*************/0";
    query.spatialRelationship=Query.SPATIAL_REL_INTERSECTS; 
    query.geometry=queryGraphic;
    query.outFields=["*"];
    query.returnGeometry=true;
    queryTask.execute(query, new AsyncResponder(onResult, onFault));
    
    function onResult(featureSet:FeatureSet, token:Object=null):void
    {  
     for each(var myGraphic:Graphic in featureSet.features)
     {    
      myGraphic.symbol=sfs;
      myGraphicsLayer.add(myGraphic);    
     }
     
     Alert.show(featureSet.features.length.toString())
    }
    function onFault(info:Object, token:Object=null):void
    {
     Alert.show(info.toString());
    }
    
    
   }

Thank you very much for answer.
Indeed, I have to work with geoprocessing services because it's the topic of my graduation project.so i well just use the geoprocessing service :).
Thanks again 🙂
