[jira] [Updated] (JENA-495) Regression in evaluation of aggregates
with trailing VALUES
[ https://issues.apache.org/jira/browse/JENA-495?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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 } }
was:
The following query returns {{x, 1},{x, 2}} with 2.7.1 and 2.10.1 as expected:

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#>

VALUES ?x { 1 2 }
