Kiet Ly commented on RYA-92:
----------------------------
CREATE GRAPH d:g3 will create an empty graph. This select will list all graph
including the empty graph.
SELECT ?g
WHERE
{ GRAPH ?g {} }
It is part of SPARQL 1.1 Update specs, see here
http://www.w3.org/TR/sparql11-update/#create. I was just checking for SPARQL
1.1 compliant.
> CREATE GRAPH throw null pointer exception
