I forgot the important part: what I want is to filter on a userID in the
person table such as -
SELECT u.Username, p.UserID
FROM Users u LEFT OUTER JOIN
Person p ON u.UserID = p.UserID
WHERE (p.UserID = 5) OR
(p.UserID IS NULL)
THis will return both the matching recs from the user table and NULLs from
the person table in sql server, but is what I cant get to work in mysql...

I don't see any obvious problems with your query. I use LEFT JOINs all the
time.
Which version MySQL are you using? Can you give us an example of what your
base data looks like (Users table and Person table), and what you actually
got as a response?
