Hi all again,
in the course of my last mail, I also thought about adding another example:
E) "Give me all persons and the first 3 (alphabetically by name) of their friends"
but I couldn't find any way to write this in an intuitive manner... ideas anyone?
I am afraid, that - by the scoping we have imposed for subqueries - that one might be difficult/impossible?
The following naive writing does't work obviously:
SELECT ?P ?F
{ ?P a :Person .
{SELECT ?P ?F { ?P :knows ?F . ?F name ?N } ORDER BY ?N LIMIT 3 }
}
I also think I recall that we had this discussion already some time back in some other form,
but I can't recall the outcome :-|
Anyone to help?
Axel
