> --------------------------------------------------

> Project: Apache Drill
> Issue Type: Bug
> Components: Execution - Data Types
> Affects Versions: 1.8.0
> Reporter: Robert Hou
> Assignee: Volodymyr Vysotskyi
> Attachments: test_table

>
> This query returns the wrong result
> {code:sql}
> 0: jdbc:drill:zk=10.10.100.186:5181/drill/rho> select count(\*) from
> test_table 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:
> {code:sql}
> 0: jdbc:drill:zk=10.10.100.186:5181/drill/rho> select count(\*) from
> test_table where (int_id > -3025 and bigint_id <= -256) or (double_id >= -255
> and double_id <= -5);
> +---------+
> | EXPR$0 |
> +---------+
> | 3020 |
> +---------+
> {code}
> By itself, the result is also correct:
> {code:sql}
> 0: jdbc:drill:zk=10.10.100.186:5181/drill/rho> select count(\*) from
> test_table where (cast(double_id as bigint) >= -255 and double_id <= -5);
