[GitHub] [arrow-datafusion] Dandandan opened a new issue, #3927: Support `SubqueryAlias` better in rules

[GitBox <gi...@apache.org>]

Dandandan opened a new issue, #3927:
URL: https://github.com/apache/arrow-datafusion/issues/3927

   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   DataFusion has `SubqueryAlias` in the logical plan. Currently it is only supported to be used in a table scan.
   The current code dealing adding alias to projections is relatively complex and brittle.
   This limits the usage / support of it for subqueries. 
   
   **Describe the solution you'd like**
   Replace the usage of projections with alias with  `SubqueryAlias`. Deprecate usage of Projection with alias.
   
   **Describe alternatives you've considered**
   
   **Additional context**
