Re: [Virtuoso-users] Loops and conditionals with SPARQL

Hello Leyla, Maybe I've missed something but the query yon need does not require even using subqueries, just a plain SPARQL: SELECT * WHERE { ?sub xxx:hasPrice ?obj, ?obj1 . ?obj xxx:hasMinPrice ?min . ?obj xxx:hasMaxPrice ?max . ?obj1 xxx:hasMinPrice ?min1 . ?obj1 xxx:hasMaxPrice ?max1 .

[Virtuoso-users] Loops and conditionals with SPARQL

Hello there, I have an object property which can appear more than once. It defines min and max values for prices which should not overlap and I need to check it. 300.0 450.0 100.0 200.0 I think I can do it with SPARQL and loops. For each

Re: [Virtuoso-users] VSP and Sparql use VPL variables in query.

Thanks, Ivan. My first intuition would say that a sparql query containing { _:hidden_bnode skos:prefLabel ?v1_lab . FILTER (_:hidden_bnode = iri(?:_uri)) } could be inefficient. Will Virtuoso internally optimize this into a query equivalent to { $:some_uri skos:prefLabel ?v1_lab. } ? Lourens

Re: [Virtuoso-users] VSP and Sparql use VPL variables in query.

Lourens, I gues that this will work: CREATE PROCEDURE VAS_PROPERTY_LABEL (in _uri varchar) { for (sparql select ?v1_lab where { `iri(?:_uri)` skos:prefLabel ?v1_lab}) do { RETURN "v1_lab"; } RETURN _uri; } Colon in ?:_uri indicates an external variable, iri() con
