Subject [jira] Commented: (JDO-245) JPOX must throw JDOUserException for queries specifying having clause refering fields which are not part of the result clause.

Craig Russell commented on JDO-245:
-----------------------------------

Yet another comment. The title of this JIRA is the HAVING clause containing fields that are
not part of the result clause. Actually, it's legal for any aggregate expression to be in
the HAVING clause regardless of whether it is in the result.

So maybe we need another positive test for HAVING that has an expression that isn't contained
in the SELECT clause. 
e.g. SELECT department, AVG(weeklyhours) FROM Employee GROUP BY department HAVING COUNT(personid)
> 1 

And another negative test for HAVING that uses a term that's not an aggregate.
SELECT department, AVG(weeklyhours) FROM Employee GROUP BY department HAVING middlename !=
NULL
