[jira] [Updated] (JENA-2205) buggy values replacement in ParameterizedSparqlString
[ https://issues.apache.org/jira/browse/JENA-2205?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Rob Vesse updated JENA-2205:
----------------------------
Description:
When doing the following:
{noformat}
final String pquerys = "select * { VALUES ?l {?lrepl} ?l ?p ?o }";}}
final List<Literal> vlist = new ArrayList<>();
vlist.add(ResourceFactory.createStringLiteral("a"));
vlist.add(ResourceFactory.createStringLiteral("b"));
final ParameterizedSparqlString pquery = new ParameterizedSparqlString(pquerys);
pquery.setValues("lrepl", vlist);
final String res = pquery.toString();
System.out.println(res);
{noformat}
the result is the following syntaxically incorrect query:
{noformat}
select * { VALUES ?l {("a") ("b")} ?l ?p ?o }
{noformat}
which should be
{noformat}
select * { VALUES ?l {"a" "b"} ?l ?p ?o }
{noformat}
I think this can be fixed in a relatively straightforward way by removing the addition of parentheses in
