Van Halbert commented on TEIID-3573:
------------------------------------
The issue with changing SupportNot = False, is that the pushed down criteria is no longer
done and end up doing table scans.
The combination of intNum <> 23 and intNum is Null criteria is an issue in both
cases.
But in the first case where supportNot = TRUE, <null> values are returned in the
result set when only specifying intNum <> 23.
Infinispan-dsl-cache translator: Operator <> incorrectly
handles NULL values

https://issues.jboss.org/browse/TEIID-3573
Project: Teiid
Issue Type: Bug
Components: Misc. Connectors
Affects Versions: 8.7.1
Reporter: Filip Elias
Assignee: Van Halbert
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.
