Okay so I dug through it and found the error is coming from the following call chain: - The `LogicalPlanBuilder` returned by the `parse_join` calls `join_using` on the builder ([link](https://github.com/apache/datafusion/blob/main/datafusion/sql/src/relation/join.rs#L151)) - The `left_keys` calculation from `join_using` calls the `LogicalPlanBuilder` method, `normalize` ([link](https://github.com/apache/datafusion/blob/main/datafusion/expr/src/logical_plan/builder.rs#L1127)) - The `normalize` method calls the `Column` struct method, `normalize_with_schemas_and_ambiguity_check` ([link](https://github.com/apache/datafusion/blob/main/datafusion/expr/src/logical_plan/builder.rs#L976)) - The `normalize_with_schemas_and_ambiguity_check` build a schema error for `FieldNotFound` because the passed `using_columns` argument is empty ([link](https://github.com/apache/datafusion/blob/main/datafusion/common/src/column.rs#L219)) This appears to be due to something happening here in the sql unparser ([link](https://github.com/apache/datafusion/blob/main/datafusion/sql/src/unparser/plan.rs#L1276)). I am still working out exactly what is going wrong but wanted to give an update. -- This is an automated message from the Apache Git Service.
