nuno-faria opened a new issue, #19998: URL: https://github.com/apache/datafusion/issues/19998
### Describe the bug The `generate_series` scalar function returns an empty list when the range is invalid, while the `generate_series` table function returns an error. Other systems, like Postgres, DuckDB, and SQLite, return an empty set. ### To Reproduce ```sql > select generate_series(0, -1); +-------------------------------------+ | generate_series(Int64(0),Int64(-1)) | +-------------------------------------+ | [] | +-------------------------------------+ > select * from generate_series(0, -1); Error during planning: Start is bigger than end, but increment is positive: Cannot generate infinite series ``` ### Expected behavior Return an empty set when the range is invalid. ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
