mihailoale-db opened a new pull request, #50325:
URL: https://github.com/apache/spark/pull/50325

   ### What changes were proposed in this pull request?
   We collect temporary variables while resolving identifier clause to throw 
later if needed.
   
   ### Why are the changes needed?
   This is needed to align the use case with correct semantics (temporary 
variables are **not** allowed in persisted views).
   
   ### Does this PR introduce _any_ user-facing change?
   Users won't be able to have temporary variables in persisted views (the 
feature was broken anyways).
   
   ### How was this patch tested?
   Added test.
   
   ### Was this patch authored or co-authored using generative AI tooling?
   No.
