Re: simple SQL question

Fair comment, but my question applies to any sort of data, not just temporal. Anyway, I am storing my 'time' as a Unix timestamp and I just want to retrieve the rows with the top 10 (highest) values.

I'm suspicious of rownum - any gurus tell me if this would work as I described above:

select rownum r, headline, timestamp
from news where rownum between 1 and 3
order by timestamp;

Thanks,
