query data from a web service

sundussabbah · ‎04-23-2015

Hello everybody, I'm trying to query some data from a service table I wrote: var query = new Query(); query.outFields = [ " * " ]; query.returnGeometry = true; var queryTask = new QueryTask("url"); queryTask.execute(query,showResults); but the showResult is never executed , what is the reason ?? please help me

Ok, thank you, I understand now

KushendraShah1 · ‎01-19-2016

Tom, is there way you can make spatial query on feature layer that return geometry spatially without returning attributes? Thanks

TomSellsted · ‎01-19-2016

Kushendra,

Yes! You specify an empty array for outFields and specify the query geometry. Something like:

query.geometry = webMercatorUtils.webMercatorToGeographic(firstGraphic.geometry)

query.spatialRelationship = Query.SPATIAL_REL_TOUCHES;

query.outFields = [];

queryTask.execute(query);

Regards,

Tom

Satyanarayana,

Can you be more specific about the problem you are having with your script? What is it not doing?
