[thelist] A Little Query Question

How about this:
SELECT TOP 10 FROM (SELECT TOP 20 field1, field2 FROM table1) ORDER BY
keyID
DESC
The sub query selects the top 20. Then the top query selects the top 10
from the sub set, but orders it backwards by the keyID. The keyID by
defenition always gets bigger by each row, so you are bound to get the last
10 of the top 20. Right?
But, as always I would be open to better ideas.
Thanks!
