I'm not sure about any of the rest, but I know SQLite and MySQL don't have any "default" row ordering. In those two dialects, at least, the following snippet grabs the 15th entry from the_table, sorting by the date/time it was added:
SELECT * FROM the_table ORDER BY added DESC LIMIT 1,15(of course, you'd need to have an added DATETIME field, and set it to the date/time that entry was added...)
