i'm using sql server 2008.

I have a table that looks like this:

http://sqlfiddle.com/#!3/6e117/2

How would I write a query that looks at the EVENTDATETIME column and returns the most recent concert for each artist.

So the result set would show only the most recent concert for each artist.
The result set would look something like this:

That would be a simple GROUP BY on artist, and MAX date.
SELECT Artist, Max(EventDateTime) as most_recent_event_dt
FROM TestTable
GROUP BY Artist

Open in new window

If you'd like some more reading on GROUP BY I have an image and code-heavy tutorial out there called SQL Server GROUP BY Solutions

SELECT * FROM TestTable WHERE EventDateTime IN ( SELECT  MAX(EventDateTime)  FROM TestTable GROUP BY artist )
