What you describe seems similar to the `usize` `index` in `physical_plan` [Column](https://docs.rs/datafusion/latest/datafusion/physical_expr/expressions/struct.Column.html) references. And as I recall @houqp added exactly to handle this case of ambiguous schema 🤔 I believe Postgres has a similar way of addressing fields (it does so by index rather than column name) in its logical exprs. The downside I remember from working wit postgres was that there were many potential hard to track down issues when the indexes got messed up. It might be interesting to see what this would look like in DataFusion 🤔 -- This is an automated message from the Apache Git Service.
