Blajda opened a new issue, #7165: URL: https://github.com/apache/arrow-datafusion/issues/7165
### Is your feature request related to a problem or challenge? In the delta-rs project we support operations such as delete, update, and merge where users can supply predicate as either a string or a DataFusion `Expr`. String predicates go through sql-parser to obtain an `Expr` and are evaluated. At the end of each operation the expression must be converted back to a string to store in the transaction log for conflict resolution. The implementations for `create_name` and `canonical_name` almost fit this need but scalar values are surrounded by their type which cannot be parsed by sql-parser. E.G `col1 = 1` becomes `col1 = Int32(1)` ### Describe the solution you'd like Given an `Expr` one should be able to obtain it's string representation that can be parsed by sql parser. ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
