-----------------------------------------
Summary: Invalid results of SPARQL query with a federated subquery
Key: JENA-2280
URL: https://issues.apache.org/jira/browse/JENA-2280
Project: Apache Jena
Issue Type: Bug
Components: Fuseki
Affects Versions: Jena 4.4.0, Jena 4.3.2, Jena 4.3.1
Reporter: Michal Pietrusinski
In Fuseki I created on dataset named "test".
The following query gives 1 result with an empty string, whereas the expected
value is "test"
{code:java}
SELECT ?temp
WHERE {
{
SELECT (?value as ?temp) {
{ SERVICE <http://localhost:3030/test/query> {
VALUES ?value \{ "test" }
}
}
}
}
}
{code}
However the following query returns the correct result "test".
{code:java}
SELECT *
WHERE {
{
SELECT (?value as ?temp) {
{ SERVICE <http://localhost:3030/test/query> {
VALUES ?value \{ "test" }
}
}
}
}
}
{code}
Both of these queries work fine on an older Fuseki release 4.1.0
