### 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 latest-master ### What's Wrong? 1. create test table: ``` CREATE TABLE `t3` ( `k1` int(11) NULL, `a1` int(11) NULL ) ENGINE=OLAP DUPLICATE KEY(`k1`) COMMENT 'OLAP' DISTRIBUTED BY HASH(`k1`) BUCKETS 10 PROPERTIES ( "replication_allocation" = "tag.location.default: 1", "in_memory" = "false", "storage_format" = "V2", "disable_auto_compaction" = "false" ); ``` 2. insert test data `insert into t3 values(1,1),(2,2),(3,3),(4,null),(null,5);` 3. wrong result with SQL: ``` > select min(k1) from (select k1,a1 from t3 union select null,null) t; +-----------+ | min(`k1`) | +-----------+ | 0 | +-----------+ ``` 4. correct min(k1) should be 1, such as: ``` > select min(k1) from (select k1 from t3 union select null) t; +-----------+ | min(`k1`) | +-----------+ | 1 | +-----------+ ``` ### What You Expected? +-----------+ | min(`k1`) | +-----------+ | 1 | +-----------+ ### How to Reproduce? _No response_ ### Anything Else? _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
