Geocode using ArcGIS Geocoding service in SQL

I would like to geocode addresses in a SQL table using a ArcGIS geocoding service.  The service is located here: http://gis.hennepin.us/arcgis/rest/services/Locators/HC_COMPOSITE/GeocodeServer
I found a great example of what I am trying to do here:

but this example is using Bing maps and XML.  I would like to use ArcGIS service and JSON.  Any help would be greatly appreciated.  Thanks
