Hi Ivan:
I'm using Virtuoso Conductor as client to check the syntax of my queries

I'm attaching a screen shot
thanks in advance

too much time if performed exactly as written.
Fortunately, almost all real datasets have at least one rdf:type
Hello all,

empty result set:
select distinct ?g
where { graph ?g {?s ?p ?o} }
However, the following returns the expected results (even if the limit is

Hi Alex,
Note also, development have confirmed that there aren't any special methods in
