Dear all,
I experience some problems with query execution over jena. For some reason I
cannot execute the following query to my local TDB:
String queryString =
"PREFIX
dqm:<http://purl.org/dqm-vocabulary/v1.1/dqm#>" +
"PREFIX
xsd:<http://www.w3.org/2001/XMLSchema#>" +
"SELECT ?dqr ?i" +
"WHERE {" +
"?dqr a dqm:PropertyCompletenessRule ." +
"?dqr dqm:testedClass ?tclass ." +
"?dqr dqm:testedProperty1 ?tprop ." +
"?dqr dqm:requiredValue
\"true\"^^xsd:boolean ." +
"?dqr dqm:requiredProperty
\"true\"^^xsd:boolean ." +
"?tclass dqm:hasURI ?tclassreal ." +
"?tprop dqm:hasURI ?tpropreal ." +
"BIND (IRI(str(?tpropreal)) AS ?tpropURI) ."
+
"BIND (IRI(str(?tclassreal)) AS ?tclassURI)
." +
"{" +
"?i a ?tclassURI ." +
"NOT EXISTS{" +
"?i ?tpropURI ?value ." +
"}" +
"}UNION{" +
"?i a ?tclassURI ." +
"?i ?tpropURI \"\"." +
"}" +
"}";
String directory = "D:/Fuseki-0.2.0/DB" ;
Dataset ds = TDBFactory.createDataset(directory) ;
Query query =
QueryFactory.create(queryString,Syntax.syntaxSPARQL_11);
QueryExecution qe = QueryExecutionFactory.create(query, ds);
ResultSet results = qe.execSelect();
System.out.print(ResultSetFormatter.asText(results));
When I execute the above code, I receive the following error:
Exception in thread "main" com.hp.hpl.jena.query.QueryParseException:
Encountered " <NOTEXISTS> "NOT EXISTS "" at line 1, column 478.
Was expecting one of:

Other queries without NOT EXISTS work fine. The query also executes on
FUSEKI's query UI without any problems.
Thanks for your help,
Christian
