Try the folowing querys:
=> SELECT * FROM myTable ORDER BY myColumn DESC LIMIT
5;
That is exactly the last 5 rows of the query:
=> SELECT * FROM myTable ORDER BY myColumn;
Unfortunately, the tuples are in the opposite order
(thanks to DESC).
If the opposite order is a problem, I guess you could
do a workaround, like this:
=> CREATE VIEW myView AS SELECT * FROM myTable ORDER
BY myColumn DESC LIMIT 5;
=> SELECT * FROM myView ORDER BY myColumn ASC;
=> DROP VIEW myView;
I can't think of any problem with the second one
except speed, but i don't think there are any other
ways to do it; if there are I would like to know.
Hope it helps,
