[GitHub] [spark] viirya commented on pull request #33183: [SPARK-35972][SQL] When replace ExtractValue in NestedColumnAliasing we should use semanticEquals

   Doesn't the query shown in the PR description look the same as `sql("select employer.company, employer.company.name, employer.company.address from contacts")` in `SchemaPruningSuite`? It is basically querying a nested struct (`employer.company`) and a few nested columns inside the struct.
   
   I ran such query in `SchemaPruningSuite`. It seems working without any error?
