niebayes opened a new issue, #16914: URL: https://github.com/apache/datafusion/issues/16914
We recently encountered a bug caused by our misuse of the `datafusion::logical_expr::col` helper function, which does not preserve the case of the column name. We’re aware that `Column::from_name` and `Column::from_qualified_name_ignore_case` are available for creating Column instances while preserving or explicitly ignoring case. Given this, would it make sense to introduce a helper function such as `col_case_preserved` (or a better name) to create Column expressions with case sensitivity preserved by default? Alternatively, we could consider modifying the existing col function to accept an additional parameter, such as `ignore_case`, to give users control over case sensitivity directly. -- This is an automated message from the Apache Git Service.
