> Key: JENA-432
> URL: https://issues.apache.org/jira/browse/JENA-432
> Project: Apache Jena
> Issue Type: Bug
> Components: ARQ
> Affects Versions: Jena 2.10.0
> Reporter: Simon Helsen
>
> The following test query:
> SELECT ?test ?s1
> WHERE {
> ?test ?p1 ?o1.
> FILTER ( ?test = <http://localhost/t1> || ?test = <http://localhost/t2> )
> OPTIONAL {
> SELECT ?s1
> { ?s1 ?p2 ?o2 }
> }
> }
> produces the following plan:
> (project (?test ?s1)
> (disjunction
> (table empty)
> (table empty)))
> Something goes wrong with the FILTER expansion. As a workaround, we observed
> that the following variation:
> SELECT ?test ?s1
> WHERE {
> { ?test ?p1 ?o1.
> FILTER ( ?test = <http://localhost/t1> || ?test = <http://localhost/t2> )
>
> }
> OPTIONAL {
> SELECT ?s1
> { ?s1 ?p2 ?o2 }
> }
> }
> produces the correct plan:
> (project (?test ?s1)
> (leftjoin
> (disjunction
> (assign ((?test <http://localhost/t1>))
> (bgp (triple <http://localhost/t1> ?p1 ?o1)))
> (assign ((?test <http://localhost/t2>))
> (bgp (triple <http://localhost/t2> ?p1 ?o1))))
> (project (?s1)
> (bgp (triple ?s1 ?/p2 ?/o2)))))
