| JPOX: issues with the default Unique setting for aggregate queries
--------------------------------------------------------------------
Key: JDO-383
URL: http://issues.apache.org/jira/browse/JDO-383
Project: JDO
Type: Bug
Components: tck20
Versions: JDO 2 final
Reporter: Michael Bouschen
Assigned to: Erik Bengtson
Priority: Minor
Fix For: JDO 2 maintenance release 1
The JDOQL query Unique flag defaults to true for a query with a single result expression and the result expression is an aggregate (COUNT, MIN, MAX, AVG, SUM). JPOX calculates the correct default value for Unique if the result expression is specified w/o
any whitespaces between the aggreagte keyword and the expression in parenthesis: setResult("MIN(budget)"). However, JPOX defaults the Unqiue flag to false, if there is a blank after the aggregate keyword: setResult("MIN (budget)").
With the fix of JDO-381 the TCK test class DefaultUnique in package org.apache.jdo.tck.query.result fails, because I added some test queries having a blank after the aggregate keyword. They now return a list with the aggregate value instead of the value i
tself.
