I'll pose the question like this: I have an Access database, and a table with all the individual sales for five different salesmen. I want a query that will give me the top ten sales for each salesman.
This query, like so many other queries dealing with "top N" results, contains within it the thorny issue of what to do about ties. I'm not even going to mention the issue beyond saying that you should be prepared for the inevitable questions from your users.
In Access, you can use TOP syntax. This makes the necessary correlated subquery a lot easier to write.
select s.id , s.name , s.sales from salestable s where s.sales in ( select top 10 sales from salestable where id = s.id order by sales desc ) order by s.id , s.sales desc
