Andy Jefferson commented on JDO-568:
------------------------------------
When looking at the "correlated" tests with this "candidateExpression", what is
the expected result of calling execute() on a subquery of that form, for example
Query q = pm.newQuery("SELECT AVG(e.weeklyhours) FROM this.department.employees
e");
q.execute();
I'd expect JDOUserException since the query can only be used as a subquery (the
candidate expression is by no means a "candidate-class-name" in 14.6.13), but
this would need to be added to the spec in 14.6.1
> Add subquery support to JPOX
