The ScalarVariable is represented in terms of `DataType`, and thus plans can't https://github.com/apache/datafusion/blob/6ecf76c83043990c253a84d81217349c09258220/datafusion/expr/src/expr.rs#L313-L314 While we are here, it would probably be a good idea to allow the nullability to be represented here as well as most other logical expression members can store this, too. ### Describe the solution you'd like Perhaps the DataType could be updated to a FieldRef or FieldMetdata could be added ### Describe alternatives you've considered _No response_ ### Additional context - Issue for updating Cast: https://github.com/apache/datafusion/issues/18060 - Issue for updating Placeholder: https://github.com/apache/datafusion/issues/17862 -- This is an automated message from the Apache Git Service.
