Transaction On Update

I have a simple update:


begin transaction
update table1
set column1 = 10
where column2 = 'ABC'
If @@Error > 0 then
rollback transaction
else
commit transaction
print 'show all updated fields'
go


What i want to achieve is if transaction is successful, i would like to see which fields were updated (in form of report or something like following below:

column0 | column1 | column2
---------------------------
1 | 10 | ABC
21 | 10 | ABC
12 | 10 | ABC
251 | 10 | ABC

4 row(s) updated.

There should be a clause like OUTPUT, but don't know how to use it :-(

thank you
