> I'm not sure about the full scope of this issue.  In testing TEIIDSB-213 I can see that a query such as:
> select a1.id from Account a1 inner join account a2 on a1.parentid = a2.id
> which results in the source query with the implicit null check:
> SELECT Id FROM Account WHERE ParentId != NULL
> actually returns results, but no are expected.
> The explicit non-join query query
> select a1.id from Account a1 where a1.parentid is not null
> result in:
> SELECT Id FROM Account WHERE ParentId != NULL
> but returns no results
> So there is something in the join handling that is not working as expected.
