How do you return the array of markers created in Google Maps using a fusion table query?

问题

Here's what I have and it shows the markers on the map, but I need the actual marker locations returned by the query. Any ideas? Thanks!

function queryFusionTable(lat, lng, radius) {

  var spatialCondition = "ST_INTERSECTS(location, CIRCLE(LATLNG(" + lat + ", " + lng + ")," + radius + ")) "; 

  layer.setOptions({
      query: {
        select: 'location',
        from: tableid,
        where:  spatialCondition
      },
     });

 }
