Unexpected result for HAVING (bound(...)) expression

[bouffard....@ireq.ca]

Running the following query on an empty database:

SELECT ?x (COUNT(?y) as ?count)

WHERE { ?x a ?y }

GROUP BY ?x

HAVING (bound(?x))

I would expect to get no results since the HAVING clause should filter out the empty grouped solution set. I validated this expectation with the latest releases of Jena, Sesame and dotNetRDF. However Stardog 2.1.1 returns an empty row. Is that expected ?

Thanks,
Alexandre

No, that's a bug and it will be fixed in the next release.

Cheers,

Mike

 

Thanks,
