> I just updated to v2.1.0 from v2.0.1 and noticed that a query using TYPE()
> <> X is no longer working. I have an abstract base class and two
> subclasses. My query asks for all but one of the subclasses, like this:
> SELECT d FROM AbstractClass d WHERE d._state = :state AND TYPE(d) <>
> SubClassTwo
> When I run this query with v2.1.0, the SQL is generated as if the query
> said
> "TYPE(d) = SubClassTwo", resulting in a match on
> the SubClassTwo discriminator. I found a work-around using NOT IN:
> SELECT d FROM AbstractClass d WHERE d._state = :state AND TYPE(d) NOT IN
> (SubClassTwo)
