URL: https://github.com/apache/incubator-doris/issues/9210
### Search before asking
- [X] I had searched in the [issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and found no similar issues.
### Version
dev-1.0.1
### What's Wrong?
Step 1:
CREATE TABLE `test1` (
`goods_id` bigint(20) ,
`goods_name` varchar(200),
`day_sale` int(11) ,
`date` date
)
UNIQUE KEY(`goods_id`)
DISTRIBUTED BY HASH(`goods_id`) BUCKETS 10
PROPERTIES
(
"replace_if_not_null" = "true"
);
Step 2:
INSERT INTO test1 ( `goods_id`, `goods_name`, `day_sale`, `date` )
VALUES
( 1, "good1", 10, '2022-04-20' ),
(2, "good2",12,'2022-04-20');
MySQL [test]> select * from test1;
+----------+------------+----------+------------+
| goods_id | goods_name | day_sale | date |
+----------+------------+----------+------------+
| 2 | good2 | 12 | 2022-04-20 |
| 1 | good1 | 10 | 2022-04-20 |
+----------+------------+----------+------------+
2 rows in set (0.01 sec)
Step 3：
INSERT INTO test1 ( `goods_id`, `goods_name`, `day_sale`, `date` )
VALUES
( 1, NULL, 11, '2022-04-20' ),
(2,NULL,13,'2022-04-20');
MySQL [test]> select * from test1;+----------+------------+----------+------------+
| goods_id | goods_name | day_sale | date |
+----------+------------+----------+------------+
| 2 | NULL | 13 | 2022-04-20 |
| 1 | NULL | 11 | 2022-04-20 |
+----------+------------+----------+------------+
2 rows in set (0.01 sec)
Expect:
MySQL [test]> select * from test1;
+----------+------------+----------+------------+
| goods_id | goods_name | day_sale | date |
+----------+------------+----------+------------+
| 2 | good2 | 13 | 2022-04-20 |
| 1 | good1 | 11 | 2022-04-20 |
+----------+------------+----------+------------+
2 rows in set (0.01 sec)
### What You Expected?
MySQL [test]> select * from test1;
+----------+------------+----------+------------+
| goods_id | goods_name | day_sale | date |
+----------+------------+----------+------------+
| 2 | good2 | 13 | 2022-04-20 |
| 1 | good1 | 11 | 2022-04-20 |
+----------+------------+----------+------------+
2 rows in set (0.01 sec)
Expect it could implement part columns updating.

I remember replace_if_not_null is a aggregate method?
use aggregate table and replace_if_not_null
