Subject [jira] [Updated] (DRILL-4970) Wrong results when casting double to bigint or int
Date Thu, 27 Oct 2016 00:52:59 GMT

Robert Hou updated DRILL-4970:
------------------------------
    Description: 
This query returns the wrong result

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);
+---------+
| 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 test_table 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 test_table where (cast(double_id
as bigint) >= -255 and double_id <= -5);
+---------+
| EXPR$0  |
+---------+
| 251     |
+---------+
