Question

I need help with SQL query.

I have two tables. One is users and other one is userfriends

users table:
aid email                    firstname 
1   [e-mail]         example
2   [e-mail]        example2
3   [e-mail]        example3
4   [e-mail]        example4

userfriends tables:
reqid     email                    friendemail               status 
1         [e-mail]        [e-mail]            1       (example1 is frnds with example2)
2         [e-mail]        [e-mail]            2       (example2 request pending)
3         [e-mail]        [e-mail]            1       (example1 is frnds with example3)
4         [e-mail]        [e-mail]            1       (example1 is frnds with example4)

So when status is 2 the add request is pending and at status 1 they are friends. What i want is that i want to retrieve the complete friendlist for user example1. I want to pull out names from users table for corresponding output from previous query to display as friendlist.

I think you guys are missing the fact that the searched for email could be in either column:

select u.firstname
from userfriends f, users u where 
u.email='[e-mail]' and f.status=1 and
(u.email = f.email and f.friendsemail='[e-mail]')
or
(u.email = f.friendsemail and f.email='[e-mail]')
