Lars Hofhansl commented on PHOENIX-3014:
----------------------------------------
This makes queries like these fail now:
{{SELECT prefix1 FROM saltedT GROUP BY prefix1, prefix2 HAVING prefix1 IN
('1','2')}}
and
{{SELECT DISTINCT prefix1, prefix2 FROM saltedT WHERE prefix1 IN ('1','2')}}
> SELECT DISTINCT pk ORDER BY pk DESC gives the wrong results
