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 resul
t 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 parenthe
sis: setResult("MIN(budget)"). However, JPOX defaults the Unqiue flag to fal
se, 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.apac
he.jdo.tck.query.result fails, because I added some test queries having a bl
ank after the aggregate keyword. They now return a list with the aggregate v
alue instead of the value i
tself.
