---------------------------------

             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);
+---------+
| EXPR$0  |
+---------+
| 2769    |
+---------+

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);
+---------+
| EXPR$0  |
+---------+
| 251     |
+---------+
