Hi Holger,
thanks for your fast reply.
Actually,
I observed that replacing "?spThing , ?area " with "?arg1 , ?arg2" in the
function body ,
it works. I don't have to specify any constraint.
I don't know if it is just a case or there is an explanation for that
behavior.
I'm just wondering if for a select function there are "keywords" to specify
as return.
Thanks
Luca
