[Virtuoso-users] Problem with advanced queries

[Safran, T. (NIH/N. [C] <sa...@ma...>]

I am having problems doing some slightly advanced queries against http.  A simple query works but other queries don’t.  Is there a deeper issue with permissions or indexes that I need to look into?

Example:  This works.

SELECT *
    FROM <http://NCIT_NG1> where { ?s ?p ?o } LIMIT 50

But this does not (note: prefix left out for brevity)
SELECT ?subject ?role ?object
    WHERE {
        ?subject rdfs:subClassOf ?an .
        ?an owl:onProperty ?role .
        ?an owl:someValuesFrom ?object .
        ?subject rdfs:subClassOf* ncit:Gene
        }
    ORDER BY asc(?subject)
