### 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? for example: ```sql select * from student join (select sid as id1, sid as id2, grade from score) s on student.id = s.id1 where s.id1 > 1 ``` Exception : org.apache.doris.common.NereidsException: Duplicate key (deptno#3 + 1) (attempted merging values deptno#6 and expr_deptno#11) In `InferPredicates`, we need pull predicates from project children then use `sid` replace `id1`. In our code, use alias name as key, use expression as value to build map. Obviously, `sid` has two alias name(id1,id2) so throw `Duplicate key` exception. ### What You Expected? correct ### How to Reproduce? _No response_ ### Anything Else? _No response_ ### Are you willing to submit PR? - [X] 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.
