Chun Chang commented on DRILL-4970:
-----------------------------------

Verified fix:

0: jdbc:drill:schema=dfs.drillTestDir> select count(*) from dfs.`/tmp/test_table` where
(int_id > -3025 and bigint_id <= -256) or (cast(double_id as bigint) >= -255 and
double_id <= -5);
+---------+
| EXPR$0  |

| 3020    |
+---------+

0: jdbc:drill:schema=dfs.drillTestDir> select count(*) as c from (values(-255.0)) as t(double_id)
where (cast(double_id as int) >= -255 and double_id <= -5) or (double_id <= -256);
