Question

I have a query I’m designing which grabs data from multiple different tables. In MS Access 2010, how would I create one of the query columns so that it returns the most recent date out of a series of dates, for each user in the table:

Sample data from table:

userid: | appointment:
000001  | 05/10/2009
000001  | 05/10/2010
000001  | 05/11/2010
000002  | 05/12/2009
000002  | 30/12/2010

expected output for field query:

userid:  | appointment:
000001   | 05/11/2010
000002   | 30/12/2010

Answer 1

SELECT userid, Max(appointment) AS most_recent
FROM YourTable
GROUP BY userid;
