413331861 opened a new issue, #15675:
URL: https://github.com/apache/doris/issues/15675
### Search before asking
- [X] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues.
### Version
1.2.0
### What's Wrong?
建表信息如下：
create table xxx (.....)
UNIQUE KEY(`account_id`)
COMMENT 'OLAP'
DISTRIBUTED BY HASH(`account_id`) BUCKETS 1
PROPERTIES (
"replication_allocation" = "tag.location.default: 5",
"in_memory" = "true",
"storage_format" = "V2",
"enable_unique_key_merge_on_write" = "true",
"disable_auto_compaction" = "false"
);
根据key查询结果如下：
MySQL [tmp]> select count(1),count(distinct account_id) from xxx ;
+----------+------------------------------+
| count(1) | count(DISTINCT `account_id`) |
+----------+------------------------------+
| 5441977 | 5203241 |
+----------+------------------------------+
1 row in set (0.49 sec)
MySQL [tmp]> select account_id,count(1) cnt from xxx group by account_id having cnt > 1 limit 10;
+---------------------+------+
| account_id | cnt |
+---------------------+------+
