Finding a record in a result set

[James Tu]

Is there some quick way to do the following in MySQL?  (I know I can  
use PHP to search through the result set, but I wanted to see if  
there's a quick way using some sort of query)

Let's say I know that Joe is from Maine.
I want to do a query of all employees from Maine, ordered by hiring  
date, and figure out where Joe falls in that list. (i.e. which record  
number is he?)
