Mark Buquor updated JENA-495:
-----------------------------
Description:
The following query returns \{\{x, 1},{x, 2}} with 2.7.1 and 2.10.1 as expected:
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
SELECT *
WHERE { }
VALUES ?x { 1 2 }
The following query returns \{\{sum,3}} with 2.7.1. With 2.10.1, it returns no
results.
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
SELECT (SUM(?x) AS ?sum)
WHERE { }
VALUES ?x { 1 2 }
The following query returns \{\{count,2}} with 2.7.1. With 2.10.1, it returns
\{\{count,0},{count,0}}.
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
SELECT (COUNT(?x) AS ?count)
WHERE { }
VALUES ?x { 1 2 }
The queries work as expected with 2.10.1 if the VALUES is moved into the WHERE.
e.g.
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
SELECT (COUNT(?x) AS ?count)
WHERE { VALUES ?x { 1 2 } }

VALUES ?x { 1 2 }
The following query returns {{sum,3}} with 2.7.1. With 2.10.1, it returns no
results.

SELECT (SUM(?x) AS ?sum)
WHERE { }
VALUES ?x { 1 2 }
The following query returns {{count,2}} with 2.7.1. With 2.10.1, it returns
{{count,0},{count,0}}.
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
SELECT (COUNT(?x) AS ?count)
WHERE { }
VALUES ?x { 1 2 }
The queries work as expected with 2.10.1 if the VALUES is moved into the WHERE.

SELECT (COUNT(?x) AS ?count)
WHERE { VALUES ?x { 1 2 } }
