Krystal created DRILL-4722:
------------------------------
Summary: date_add() function returns incorrect result with
interval hour, minute and second
Key: DRILL-4722
URL: https://issues.apache.org/jira/browse/DRILL-4722
Project: Apache Drill
Issue Type: Bug
Components: Functions - Drill
Reporter: Krystal
Fix For: 1.7.0, 1.6.0
The following query returns the same data for the second column as the first:
select date_add(cast('2015-01-24 07:27:05.0' as timestamp), interval '3' HOUR),
date_add(cast('2015-01-24 07:27:05.0' as timestamp), interval '5' HOUR) from
(values(1));
+------------------------+------------------------+
| EXPR$0 | EXPR$1 |
+------------------------+------------------------+
| 2015-01-24 10:27:05.0 | 2015-01-24 10:27:05.0 |
+------------------------+------------------------+
If each column is run separately, then it produces correct result:
select date_add(cast('2015-01-24 07:27:05.0' as timestamp), interval '3' HOUR)
from (values(1));
+------------------------+
| EXPR$0 |
+------------------------+
| 2015-01-24 10:27:05.0 |
+------------------------+
select date_add(cast('2015-01-24 07:27:05.0' as timestamp), interval '5' HOUR)
from (values(1));
+------------------------+
| EXPR$0 |
+------------------------+
| 2015-01-24 12:27:05.0 |
+------------------------+
Same problem is seen for interval of minute and second:
select date_add(cast('2015-01-24 07:27:05.0' as timestamp), interval '50'
MINUTE), date_add(cast('2015-01-24 07:27:05.0' as timestamp), interval '40'
MINUTE) from (values(1));
+------------------------+------------------------+
| EXPR$0 | EXPR$1 |
+------------------------+------------------------+
| 2015-01-24 08:17:05.0 | 2015-01-24 08:17:05.0 |
+------------------------+------------------------+
select date_add(cast('2015-01-24 07:27:05.0' as timestamp), interval '50'
second), date_add(cast('2015-01-24 07:27:05.0' as timestamp), interval '40'
second) from (values(1));
+------------------------+------------------------+
| EXPR$0 | EXPR$1 |
+------------------------+------------------------+
| 2015-01-24 07:27:55.0 | 2015-01-24 07:27:55.0 |
+------------------------+------------------------+
select date_add(cast('2015-01-24 07:27:05.0' as timestamp), interval '3' HOUR),
date_add(cast('2015-01-24 07:27:05.0' as timestamp), interval '50' MINUTE),
date_add(cast('2015-01-24 07:27:05.0' as timestamp), interval '50' second) from
(values(1));
+------------------------+------------------------+------------------------+
| EXPR$0 | EXPR$1 | EXPR$2 |
+------------------------+------------------------+------------------------+
| 2015-01-24 10:27:05.0 | 2015-01-24 10:27:05.0 | 2015-01-24 10:27:05.0 |
