Hello Ivan,
Thank you for that deep analysis and presentation of Virtuoso internals :)
It was very useful for me and I look forward to more of such
explorations with you and other developers.

I see. I'll check one more time.

Yes that was what I was trying.

Rajeev,
As far as I understand, you've intended to find out subject with
property equal to an integer 1. But "1" and 1 are two different things,
1^^xsd:int is also differs in type and { ?x urn:prop1 1. } contains a
subtle error -- dot immediately after "1" become decimal point of double
precision
Hello all,
After spending many frustrating hours trying to fix the below attached
problems, finally I figured out from the DAWG test cases that I should
be doing something like
describe ?s where {?s urn:prop1 ?o . FILTER(?o = 1). }
However. that *still* didnt work, though the test cases were wor
Hello Ivan,
Thanks for your response.
The reason I asked about it was that a particular query was not working for me.
Sample graph:
urn:foo1 urn:prop1 "1"^^xsd:integer.
urn:foo2 rdf:label "bar".
Queries:
describe ?x where {?x rdf:label "bar". } <- works, returns all the
triples with urn:foo2
Hello Rajeev,
Yes, Virtuoso supports DESCRIBE for everything that can be SELECTed.
Internally, DESCRIBE, CONSTRUCT, INSERT, DELETE and MODIFY are
implemented as user-defined aggregates applied to the output of
appropriate SELECT statement so they do not bring any additional
restrictions to SELECT
Hello all,
Does Virtuoso 5.0.3 support queries of the form:
describe ?x where { ?x foaf:name "foo" }
?
