Help with combining data from multiple rows into one column in a view

Hi, I am stumped and was hoping someone could help me out. Any help is
appreciated.


I have a view that looks sort of like this (but with a lot more
entries of course)


UniqueIdentifyier Column1 Column2
1 9999 100
2 9999 200
3 9999 300


What I want to do is to add a column to the view that will contain a
list of the values from column 2 where column 1 is the same.

UniqueIdentifyier Column1 Column2 Column3
1 9999 100 100, 200, 300
2 9999 200 100, 200, 300
3 9999 300 100, 200, 300

This may not be doable in a view, particularly if you are on SQL 2000.
