This is one of the rare cases where you need to set up a cursor and
iterate. In SQL 2000 there is no defined way to do this. (There is
a shortcut, but it relies on undefined behaviour, so I don't recommend it.)

In SQL 2005, currently in beta, the story is different. There you
actually have a way to this in a set-based statement, although the
syntax is somewhat bewildering. (It's actually a by-product, of all
the XML stuff they thrown in.)
