Decode function?

Excuse my newbie question... this might be simple for some of you. I'm working on our intranet site and have a question regarding some basic SQL statements.

I have a table of employees, their IDs, and their manager (along with other info). Some of these employees dont have a manager however (the owner for example). How would I go about displaying all the employees, ID, and their manager's full name? If the employee doesn't have a manager then the field is just blank.

It seems so simple.

Here's what I have, but it's not dynamic. I'd like to rewrite this somehow without hard coding the names:

Code:

select employee_id,full_name,
decode(manager_id,100,'Alex Ruiz',
101,'Michael Gotling',
102,'Harvey Lundgren',
103,'Jon Fellow',
124,'Karen Hatcher',
149,'Bruce Bowler',
201,'Jenny Link',
205,'Lynn Nitzbond',
null)"Manager Full Name"
from emps;

Thank you

you did not post your table structure, but I guess this should do it:

Code:

SELECT e.employee_id, e.full_name, m.full_name as "Manager Full Name"
FROM emps e, emps m
WHERE e.manager_id = m.employee_id
