Andy Seaborne created JENA-1507: ----------------------------------- Summary: GROUP BY and aggregates when there are no matching of the WHERE pattern. Key: JENA-1507 URL: https://issues.apache.org/jira/browse/JENA-1507 Project: Apache Jena Issue Type: Bug Components: ARQ Affects Versions: Jena 3.6.0 Reporter: Andy Seaborne Assignee: Andy Seaborne
There are two bugs in ARQs handling of grouping when there are no results in the WHERE clause. When there is a GROUP BY, the outcome should be no rows. * JENA-1487 * [users list discussion|https://lists.apache.org/thread.html/72c2045e639c589880619443beafec5be963733e0f9f0887e134d467@%3Cusers.jena.apache.org%3E] When there is no GROUP BY, no aggregates, and no pattern match, the result should be one row of no columns; when there is no GROUP BY, the result is always one row. It returns zero rows (v3.6.0 and before). -- This message was sent by Atlassian JIRA (v7.6.3#76005)
