Dear andy
Thanks for clarification,
1) select ?film where { ?film rdf:type movie:film . Filter(?release_date>=
"2010-12-31"^^xsd:date ) }
Does not set ?release_date
2) select ?actor where { ?film rdf:type movie:film . ?film movie:hasActor
?actor . }
Yes - loop in the results of the first query, passing in a QuerySolution
each time to the second.
Is there any option to pass all my results of ?film say 1000bindings
as query solution ones instead of looping externally?
Only by using BINDINGS but that is rewriting the query string and if you
want to do that, then just merge the two queries:
select *
where
{ ?film rdf:type movie:film .
?file movie:date ?release_date # Or whatever the predicate is.
Filter(?release_date >= "2010-12-31"^^xsd:date )
?film movie:hasActor ?actor . }
Because I am trying to calculate some statistics over my sample second query
above based on all values
passed on selected variables from first query.
One thing what I could think of is like building the First query below as
a Sub query to the Second. But I dont know if it will work and
Try it!
I have to now look for how can I build subqueries syntactically. If you can
help me, pointing
methods to build subqueries syntactically , it will be really quick for me to
test. Hope I am not
asking stupid questions.
Thank You
