I don't know what this returns, but my guess is that it has to do with buffering of rows. You can control how much DBD::Oracle fetches at once. The best setting depends on how you're using the data, e.g. you may want to get it all at once for faster fetching or get it a few rows at a time to avoid filling up RAM.
