the thing with JOINs are you gotta JOIN a table ON another table where
something matches something else (in most cases). I tried to clean this up a
bit but im rather new to mysql.
SELECT DISTINCT
(td.td_id),
td.venue_id as ven_id,
td.td_date as td_date,
art.NAME as art_name,
art.WEB as art_url,
Dear All,
I've been hashing out this query for awhile with no luck as of yet.
Basically the query works if I put a limit of 500 or so but when I do the full
query it takes up so many resource that the database engine is useless.
Here is the query:

Thank you all so much for your help, here is my solution:

Dear All,
I'm working on a database that has a lot of inconsistencies. I have a large
query that pulls artist and venue information.
My problem is this: I'm trying to create a data feed that lists artists tour
dates, and the relation venue information corresponding to that tour date.
You want a LEFT (OUTER) JOIN, which will return nulls for the columns if no
match on the join expression.

Multiple table update is only supported from 4.04 or above. If you are using
3.x, I think you should put the result into another table, delete MSI_List
and rename the table to MSI_List.
I would also very interested to know whether there exist a more elegant
solution for 3.x.

I am unsure if I followed your example completely, but maybe this might

I think you could achieve your goal if you think of your groups as
containing one or many clients.
