### 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 master ### What's Wrong? see issue #17587, it's caused by coalesce function. e.g. app_id = coalesce(appid, "") coalesce returned an new result column, which holds a reference to another original column in schema. The new result column is inserted into a dest column, and src block cleared the original column's data, the result column's data is cleared as well. ### What You Expected? coalesce should return a copied column ### 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.
