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.

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;

i think my problem is that the parsefileTBL will have null values for the
userID for some rows. the userID is the join for the userTBL. as i stated,
this is ok, as i would like to be able to display whether or not the
parsefileTBL/university_url has a person

Hi Bruce,
I haven't reconstructed your database to test for sure, but I think your
problem is stemming from the way your joins are working.
NULLs.
Hope this helps :)

hi...
sorry for the length of this post!!
i have the following, that i somehow managed to
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.
mysql> select
-> p1.name as pname,
-> p2.statusID as ps

Hello,
I am trying to figure out a problem I am having with a query involving
multiple joins but am not having much luck.
I currently have this query working:
db1 LEFT JOIN db2 ON db1.files_groupId = db2.group_id
LEFT JOIN db3 ON db1.files_userId = db3.user_id
Basically the above is
17 matches
