I have data in a table (below), and I need to select the most recent update from each user. Here the data has been sorted by date, so the 'SomeData' column of the most recent unique value of each user. Top 1 SomeData isn't going to work because it will only return for one user. Is this even possible using only SQL?

Date        SomeData    User    ...
8/5/2010    2.2     UserC
4/5/2010    1.1     UserA
3/5/2010    9.4     UserB
1/5/2010    3.7     UserA
1/5/2010    6.1     UserB
