Is this possible in one SQL statement?

Last n entries means I want the last (highest)

Last n entries means I want the last (highest) n ids.
SELECT * FROM table WHERE id=(SELECT id FROM table ORDER BY id DESC) ORDER
BY date

I have a table with primary key id.
And if your MySQL version does NOT support sub queries you can probably just
create a temporary table and then sort that one.

This does not limit it to n entries (order by date limit n is not
sufficient as I need last (highest) n ids). And afaik, limit is not
allowed in sub-queries.

You are correct. So that maybe leaves you with a temporary table then :)
