Andy Seaborne commented on JENA-1844:
-------------------------------------
This is a different problem from JENA-1843; they aren't the same issue in
different guises.
> OpAsQuery: ORDER BY forgets Extend/Bind
> ---------------------------------------
>
> Key: JENA-1844
> URL: https://issues.apache.org/jira/browse/JENA-1844
> Project: Apache Jena
> Issue Type: Bug
> Components: ARQ
> Reporter: Claus Stadler
> Assignee: Andy Seaborne
> Priority: Major
>
> Another back-forth conversion issue of syntax/algebra that causes BINDs to
> get lost in the process:
> {code:java}
> Query expected = QueryFactory.create("SELECT * { ?s ?p ?o BIND(?s AS ?x) }
> ORDER BY ?s");
> Query actual = OpAsQuery.asQuery(Algebra.compile(expected));
> System.out.println(expected);
> System.out.println(actual);
> {code}
> Output:
> {code:java}
> expected: SELECT * { ?s ?p ?o BIND(?s AS ?x) } ORDER BY ?s
> actual : SELECT * { ?s ?p ?o } ORDER BY ?s
> {code}
