[Virtuoso-users] Problem with SPARQL query (or dataset?)

[robl]

Hi,

I have a fairly complete en version of the DBpedia dataset loaded into 
Virtuoso OS.  I can perform the following query and it returns data as 
expected :

SELECT ?p ?o WHERE { <http://dbpedia.org/resource/Programmers> ?p ?o }

Which returns one result :

p : http://dbpedia.org/property/redirect
o : http://dbpedia.org/resource/Programmer

When I execute this query however, there are no results returned :

SELECT ?o WHERE { <http://dbpedia.org/resource/Programmers> 
<http://dbpedia.org/property/redirect> ?o }

I'd expect this to return :

o : http://dbpedia.org/resource/Programmer

Have I misunderstood something here or is my virtuoso installation/data 
flawed in some way ?

Thanks,

Rob
