Thanks,

This is close, but it does not quite get the result I'm looking for, I
basically need the following MySQL query:

SELECT Calls . * , created_by.Name, handled_by.Name
FROM (
Calls
LEFT JOIN Users AS created_by ON Calls.CreatedBy = created_by.ID
)
LEFT JOIN Users AS handled_by ON Calls.HandledBy = handled_by.ID;

I've tried adapting the code you posted but I can't seem to get the
result set I need.  For example a call from 'Helen' created by Bob and
Handled by Sam, I would like to get the results:

CallerName      created_by.Name         handled_by.Name
Helen           Bob                             Sam

but I get

Calls.id        Calls.CallerName        Users.Name      Users.Name
1               Helen                   Bob                     Bob
1               Helen                   Sam                     Sam
1               Helen                   Charlie         Charlie

Any ideas?
