> The following query containing three where conditions returned wrong results. (data is too big so not included here.)
> {code}
> SELECT t.gbyi,
> Count(t.id)

> WHERE t.gbyi <= 5
> OR t.gbyi >= 11
> AND t.gbyt <> 'ooof'
> GROUP BY t.gbyi
> ORDER BY t.gbyi;
> {code}
> Wrong result, the count column is mostly wrong:
> {code}
> 0: jdbc:drill:schema=dfs.drillTestDirComplexJ> select t.gbyi, count(t.id) from `complex.json` t where t.gbyi <= 5 or t.gbyi >= 11 and t.gbyt <> 'ooof' group by t.gbyi order by t.gbyi;
