> Queries introducing correlated variables on boxed primitive fields throw an
> assertion error when they are translated to generated code in the Enumerable
> convention.
> For example, consider the following query where e.commission is a field of

> {code:sql}
> SELECT empid FROM emps e
> WHERE NOT EXISTS
> (SELECT 1 FROM depts d WHERE d.deptno=e.commission)
> {code}
