there are two ways that come to mind of doing this if you're
using some kind of auto-incrementing field (not necessarily
AUTO_INCREMENT, but any field that increases [or decreases]
with time)
this will select the entire row, but limit the query to only
return 1 result (and depending on how your order, this
result could be the highest/lowest value of the field):
(to get highest value of field id)
SELECT * FROM mytable ORDER BY id ASC LIMIT 1;
(to get lowest value of field id)
SELECT * FROM mytable ORDER BY id DESC LIMIT 1;
PS: there's probably a more efficient way to do it,
but this is what came to mind at the moment...
