### Is your feature request related to a problem or challenge? Based on the review https://github.com/apache/arrow-datafusion/pull/5709#pullrequestreview-1355510439 it is ideal to make an end to end reproducer for zero column batch issues (either with SQL or with the DataFrame API) It would be nice to ensure there aren't other issues with creating zero column batches. We have found two execs so far that return an Err ArrowError(InvalidArgumentError("must either specify a row count or at least one column")) with no column https://github.com/apache/arrow-datafusion/issues/4911 https://github.com/apache/arrow-datafusion/issues/5701 I suspect there are other exec may have the same issue. ### Describe the solution you'd like Need to find a good example to project empty-column relation (with non-empty row), ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
