Hi,
select * from t1,t2
left join t3 on t3.itemid=t1.itemid
left join t4 on t4.f2=t1.f2
mysql4.1 works, but mysql5.0 shows Unknown column 't1.itemid' in 'on clause'
If change into

If your storing files in mysql, it's best to chunk/shard your data if your
not doing so already. Example article/code at:

Thank you...All I was doing was a musqldump of the tables in my data base to
files, one file for each table. Yesterday I upgraded to mysql 5.0.27, so I will
watch it for a while. It just started happening last Saturday night, and I had
been running the system for a few months.
Thanks for you
When a query exceeds the size of the maximum allowed packet, mysqld closes
the connection. It assumes something has gone wrong with the client. There
are two max_allowed_packet variables, one for the server and one for the
client. This is documented in section A.2.9 of the documentation
http://www.
max_allowed_packet is the maximum size of a single SQL statement.
It's a setting on the server, as well as for the mysql command line
interface.
See http://dev.mysql.com/doc/refman/5.0/en/packet-too-large.html
I think 1 MB is the default; the maximum setting for MySQL 5 is 1 GB.

This work has to be done in a client, since you have to manage external
files. If the files are all uniquely named, then you could use filename as a
key.
In my case, I was linking the images to a product in another table. I used
three tables:
prod_table:
==
prod_num /* an auto-increment k
Try this...
select a.title, group_concat(c.name SEPARATOR ' & ') as name
from album a
join albumartist b on b.albumid=a.albumid
join artist c on c.artistid=b.artistid
group by a.title;

James - you should be able to do this with the GROUP_CONCAT function:

From what I can find on the web, this message is generated by an error in the

Please correct me if I am wrong.
Is this fixed in mysql 5.0.27 ?
