SPARQL "VALUES" support and alternatives

Question

I'm trying to run a query across multiple named graphs, returning the name of the graph as a column in the result set. I tried using VALUES from the SPARQL 1.1 W3 draft:

SELECT *
WHERE
{ 
    VALUES ?graph { <graph1> <graph2> <graph3> }
    GRAPH ?graph
    { 
        ?s  ?p  ?o .
    }
}

In Virtuoso this results in an error (syntax error at 'VALUES' before '?graph'). Does Virtuoso support VALUES? If not, what is the alternative?

Accepted Answer

3	Try: `SELECT * FROM NAMED <graph1> FROM NAMED <graph2> FROM NAMED <graph3> WHERE { GRAPH ?graph { ?s ?p ?o . } }` Does that do what you want? link This answer is marked "community wiki". answered 22 Nov '12, 20:10 lee 3.1k●1●9 accept rate: 36%
