I'm using Streaming Analytics to retrieve JSON messages being placed on an IoTHub. I need to be able to retrieve, and store, in a SQL Server table, the raw JSON string. I can't seem to find a way to do this. Is it possible?
No, unless you wrap the json as string in another json object that is send to the IoT Hub.
Otherwise the solution would be to try whether you can stringify / construct the json object using a Javascript function and then store it in the database.
