## Which issue does this PR close? Closes #9161. ## Rationale for this change In issue #9161, the expression `cast(a as int)` in the select list [generated](https://github.com/apache/arrow-datafusion/blob/497cb9d46c6f68de6762998c241d0860072c7909/datafusion/expr/src/expr.rs#L1687) a unqualified column named 't.a', which was then incorrectly referenced by the group by clause, leading to a schema error. After merging PR #9228, the group by clause will now preferentially reference the column of the same name from the **input**, rather than the one in the **select list**, thereby resolving the issue. I suspect there will still be similar issues, but we may need to find a new case to verify whether they truly exist. ## What changes are included in this PR? Add a test. ## Are these changes tested?
