Pajaraja opened a new pull request, #50544: URL: https://github.com/apache/spark/pull/50544
### What changes were proposed in this pull request? Add a check to UnionLoopExec that the UnionLoopRef in its subtree is referring to the correct query. This is important since if we call another rCTE from it, it will also have a UnionLoopRef which needs to not be replaced with the reference. ### Why are the changes needed? Multiple rCTEs within one WITH statement ended in an infinite recursion. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? New golden file test added. ### Was this patch authored or co-authored using generative AI tooling? No. -- This is an automated message from the Apache Git Service.
