[Virtuoso-users] sparql aggregate with condition on the aggr result

[Silvia Stefanova]

Hello,

I would like to make a SPARQL query with aggregation with a condition on 
the result of the aggregate, e.g.:

select ?s SUM(?books) as ?total
FROM <http://mygraph.person>
WHERE {?s  <http://mygraph/person/books> ?books.}
having (?total > 2) .

Would you please tell me how to make this in Virtuoso?

Regards,
Silvia
