						@StatusCode int OUTPUT,
						@StatusDescription nvarchar(MAX) OUTPUT)
AS

DECLARE @URL nvarchar(MAX)

					@StatusCode = @StatusCode OUTPUT, 
					@StatusDescription = @StatusDescription OUTPUT

IF @StatusCode >= 400
	EXEC SQLHTTP.net.RaiseHttpError @StatusCode, @StatusDescription, @Response
ELSE
	BEGIN
		EXEC SQLHTTP.net.Json_To_GlobalTable @Response, 'MapQuestAPITempGlobalTable'

		SELECT TOP 5	[incidents_fullDesc] AS [Description],
