If you are using the security features of the commercial edition then this boils down to you target named graph potentially being set to private. So yes, this is security configuration related, as long as target named-graph rather than structure of query is source of the query solution anomaly. Simple cleanup sequence: -- Remove <http://NCIT_NG1> from Private Named Graphs Group, should it be currently set to Private DB.DBA.RDF_GRAPH_GROUP_DEL ('http://www.openlinksw.com/schemas/virtrdf#PrivateGraphs','http://NCIT_NG1') ; -- Clearout perms set for 'nobody' DB.DBA.RDF_ALL_USER_PERMS_DEL ('nobody') ; -- Read privileges for 'nobody' on 'world' (public) named graphs DB.DBA.RDF_DEFAULT_USER_PERMS_SET ('nobody', 1, 0); -- Graph Security Rules Sanity Check RDF_GRAPH_SECURITY_AUDIT ( 0 ) ; [1] http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtRDFGraphsSecurity Kingsley > > > > > > *From: *"Safran , Tracy (NIH/NCI) [C]" <safr...@mail.nih.gov> > *Date: *Tuesday, October 11, 2016 at 8:59 PM > *To: *Kingsley Idehen <kide...@openlinksw.com>, > "virtuoso-users@lists.sourceforge.net" > <virtuoso-users@lists.sourceforge.net> > *Subject: *Re: [Virtuoso-users] Problem with advanced queries > > > > I am not getting any error, just an empty class list.
