> +Question:+
> Insert a rule in Cepheus-CEP while running
> +Description:+
> I am starting to explore Fiware tools and I am testing Cepheus-CEP.
> I know I can set rules and other configuration parameters in the "config.json" file that Cepheus take when I launch the service, but I don't know how to especify these rules on execution time.
> For example, a "config.json" could be:
> {
>   "host":"http://localhost:8080",
>   "in":[
>     {
>       "id":"RoomX",
>       "type":"Room",
>       "attributes":[
>         { "name":"temperature", "type":"double" },
>         { "name":"shutter", "type":"string" }
>       ]
>     }
>   ],
>   "out":[
>     {
>       "id":"ShutterX",
>       "type":"Shutter",
>       "attributes":[
>         { "name":"status", "type":"string" }
>       ]
>     }
>   ],
>   "statements":[
>     "INSERT INTO Shutter SELECT R.r.shutter as id, 'closed' as status FROM pattern [ every r=Room(temperature > 26.0) -> (timer:interval(5 sec) and not Room(temperature < 26.0 and id=r.id))] as R unidirectional LEFT OUTER JOIN Shutter.std:groupwin(id).std:lastevent() as S ON R.r.shutter = S.id WHERE S is null OR S.status = 'opened'",
>     "INSERT INTO Shutter SELECT R.r.shutter as id, 'opened' as status FROM pattern [ every r=Room(temperature < 24.0) -> (timer:interval(5 sec) and not Room(temperature > 24.0 and id=r.id))] as R unidirectional LEFT OUTER JOIN Shutter.std:groupwin(id).std:lastevent() as S ON R.r.shutter = S.id WHERE S is null OR S.status = 'closed'"
>   ]
> }
> And I want to change the statements (rules) list during execution time, Is there a query or something that I could use?
