Steven Hawkins commented on TEIID-3774:
---------------------------------------

There is a phoenix issue here.  However this is somewhat of a corner case in that it looks like the issue occurs only when computing an aggregate over a grouping column - which is valid syntax, but not commonly needed.  With an aggregate computed outside of the grouping, I don't see an issue with null values.  I'd vote for adding a KI for this.

> Phoenix driver evaluates clause HAVING MIN/MAX/AVG\(x\) = null to true. This is problem for query e.g. *SELECT stringnum FROM bqt1.smalla GROUP BY stringnum HAVING MIN(stringnum) = '1'* as result is:
> |StringNum|
> |<null>|
> |1|
