How to get only latest date and other columns from table

Question

Hi,
Table
   id          name        date
  123        a             2/3/2010
  124        b            15/2/2010
  125        c             1/1/2010
  123        a             12/4/2010
  125        c             17/2/2010
this is a table, here id,name,date is composite key.
I want to select id,name and date so that latest date (e.g., for id 123 date 12/4/2010 be selected) is selected for each id and each id and name should be selected once.
So what will be its query?
Thanks

Almost all aggregate functions (including MAX) also have analytic counterparts. The parser knows that you're using the analytic version if the keyword OVER, followed by an analytic clause in parentheses, comes after the argument. In this case, the default analytic clause is being used, so there's no need to put anything in the parentheses, but syntax still requires that they be there.
