Question

Hopefully this is pretty simple, but I’m having some trouble. I have a table that has multiple fields but basically the two that matter are ID and year. A single ID can exist in many years. How do I set up a select statement (Which I’m ultimately using in a join in another statement) so that I can retrieve all of the distinct IDS with no duplicates for the top year that they exist for?

If there is a set of records like this:

ID - Year
55 - 2000
55 - 2001
56 - 2000
56 - 2002

So basically I want something like this returned:

55 - 2001
56 - 2002

Help?
