Robert Hou created DRILL-4970:
---------------------------------
Summary: Wrong results when casting double to bigint or int
Key: DRILL-4970
URL: https://issues.apache.org/jira/browse/DRILL-4970
Project: Apache Drill
Issue Type: Bug
Components: Execution - Data Types
Affects Versions: 1.8.0
Reporter: Robert Hou
This query returns the wrong result
0: jdbc:drill:zk=10.10.100.186:5181/drill/rho> select count(*) from
orders_parts_rowgr1 where (int_id > -3025 and bigint_id <= -256) or
(cast(double_id as bigint) >= -255 and double_id <= -5);

Without the cast, it returns the correct result:
0: jdbc:drill:zk=10.10.100.186:5181/drill/rho> select count(*) from
orders_parts_rowgr1 where (int_id > -3025 and bigint_id <= -256) or (double_id
>= -255 and double_id <= -5);
+---------+
| EXPR$0 |
+---------+
| 3020 |
+---------+
By itself, the result is also correct:
0: jdbc:drill:zk=10.10.100.186:5181/drill/rho> select count(*) from
orders_parts_rowgr1 where (cast(double_id as bigint) >= -255 and double_id <=
-5);
