### 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 5.1.0 Doris version 0.15.1-rc09-d53cbef36 ### What's Wrong? ## 使用开窗函数 lead 过程中，返回乱码。 如下示例，窗口中 over( order by account_id ) 使用 lead 取 next_account_id , 若返回字段包含其他列(比如 customer_id ) 则 lead 取的数据会出现乱码。  ## 小数据量测试没有复现 创建测试表，插入较小数据无法复现。 表字段类型如下： create table test_lag_lead( `user_id` varchar(64) NOT NULL DEFAULT "EMPTY" COMMENT "用户id", `cid` varchar(255) NOT NULL DEFAULT "EMPTY" COMMENT "cid" ) ENGINE=OLAP AGGREGATE KEY(`user_id`, `cid`) COMMENT "测试开窗函数：lead/lag" DISTRIBUTED BY HASH(`user_id`) BUCKETS 2 ; ## 其他版本参考 同样的数据，同样的语句。 在 0.12 版本的 Doris 中， lead 函数返回正常， lag 函数出先乱码情况 ** version = 5.1.0 Doris version 0.12.22-release** ![Uploading image.png…]() ### What You Expected? 使用开窗函数 lead 可以返回正常数据 ### 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.
