Hello I've been tasked with doing a few queries on a large SQL Server 2000 database.

The query I'm having trouble with is "find the number of people between ages 20 and 40"

How would I do this? My previous query to get a count of everyone looks like this:

select count(rid) from people where ...

(with the ... being irrelevant conditions). I've googled some but the only thing I've found for calculating age is so large that I don't see how to embed it into a query, or it is a stored procedure which I do not have the permissions to create.

Can someone help me with this?
