Hmmm...that wouldn't work, that would only give you the very first one. You'd need a group by clause to make it work properly. Here's an example using the Northwind.Orders table:
select freight, orderdate from orders
where orderid in
(select min(orderid) from orders
group by datepart(yy,orderdate))
