Bruce,
I have reconstructed the database you have given me and used the following
query successfully (the one I originally gave you). I think there is
something wrong with your data.
SELECT
p2.
Bruce,
I'm getting the four rows with one correctly matching the userID for tom and
the others returning NULLs for the user info.

Bruce,
Try building your join table by table.. start with
SELECT
fields
FROM
fields and slowly add them
until you have the lot..
This is a good technique to find where your joins are going wrong.

Lachlan

Bruce,
A couple of questions...
Do you always expect one or more entries in the university_urlTBL for a
universityID that is in the universityTBL? If so, then you don't need to
left join the university_urlTBL from the universityTB
Bruce,
What do you get when you do this:
SELECT
*
FROM
university_urlTBL
WHERE
universityID = 40;

Hi Bruce,

First of all, since you are left joining to the university_urlTBL, you will
also need to left join to any tables you join from that table. If you don't

followup to my initial question.
i can use the following select query to get close... however, it doesn't
really use 'left joins', and i can't figure out how to arive at the results
with the user names being correctly identified.
