There were some special cases that were handled individually: - select * { <s> ?p ?o } was handled through querying the rdf:types of <s>, and performing an UNION of all related tables. This doesn't play along with parameterized variables where the subject might be a variable assigned later through the TrackerSparqlStatement. - select * { ?s ?p <o> } used similar tricks (querying <o> this time). It had all those drawbacks, plus it only worked for properties with rdfs:Resource range. - select * { ?s ?p ?o . ?p rdfs:domain <dom> } was handled specially. - select * { ?s ?p ?o } is unsupported - select * { <s> ?p <o> } was silently unhandled All those combinations are transparently handled with the tracker_triples virtual table now.
