Van Halbert commented on TEIID-3573:
------------------------------------

This will be a JDG/Infinispan issue in regards to how that equates.  Will need to get a reproducer for them so that they can decide what is right.

> Operator '<>' returns true for NULL <> 1
> Example:
> {code}
> select intKey,intNum from smallA where intNum<>1
> {code} 
> It returns also rows which have NULL in column intNum
> I believe that NULL <> 1 is not true in SQL.
