Hi Christian
Virtuoso does not support “NOT EXIST” but does have its own built in function:
FILTER (!bif:exists ((select (1) ...)))
See the following example on usage:
http://docs.openlinksw.com/virtuoso/rdfsparqlrule.html#rdfsparqlruleexamples6
LET is a Jena specific keyword

Hi Christian
Virtuoso does not support NOT EXIST but does have its own built in
function:
FILTER
Hi Christian,
NOT EXISTS is supported already.
E.g., right now at lod.openlinksw.com/sparql
both
SELECT count(*) WHERE {?s ?p Novosibirsk filter not exists { ?s ?p
Новосибирск } }
and
SELECT count(*) WHERE { { ?s ?p Novosibirsk } minus { ?s ?p
Новосибирск } }
return 313,
both
SELECT count(*)
