RE: Impossible Query?
I don't think it's impossible. It might be nicer if you could use a sub-select. But here's join. SELECT DISTINCT affiliates.id, DISTINCT sales.client_id,SUM(sales.client_id) FROM affiliates,clients,sales WHERE affiliates.id = clients.affiliate_id AND sales.client_id = clients.id; Would this do it? That should tell you how many sales each affiliate has made to each client. Sum that up, and you will get what you probably want in the end - a total referral, but at the least it should show you how the join would go. Benjamen R. Meyer -Original Message- From: Daren Cotter [mailto:[EMAIL PROTECTED]] Sent: Thursday, July 11, 2002 5:03 PM To: [EMAIL PROTECTED] Subject: Impossible Query? I have three tables, affiliates, clients, and sales. The affiliates table stores all of the information about affiliates, clients about clients, sales about sales. In the clients table, there is a field for affiliate_id (affiliates refer clients), and in the sales table there is a field for client_id. I need a query that will show me a list of all affiliates and the number of sales each affiliate has generated. I know this will involve a left join, but I can't figure it out, since it involves that third table. Which actually brings up another question: would be be better to store the affiliate_id in the sales table? The reason I do it this way, is because if an affiliate refers a client, and the client is involved in numerous sales, the affiliate should be credited each time.

RE: Migrating...
Thanks! I used the file transfer; I don't think the grants/revokes completely transferred, but that's easy enough to fix. :) Benjamen R. Meyer Hi. I had the same problem awhile back. What i did was just copy the db files to the linux server provided the mysql versions are exactly the same and the db structures are the same it works. Otherwise mysqldump and read it into the new db:) //Uffe Witness wrote: Hello. I am running a MySQL server (3.23.43) on WinME, and another server (same version) on libc6 Linux. The server on WinME is a development server, or rather has been until now, and the Linux one is my production server. At this time the Linux one is completely empty with the exception of the defaults, and I would like to migrate the WinME one over onto the Linux system and then drop the one on WinME from my line of development (I don't really need it). In looking through the documentation I have noticed that I could do the following: 1) Uni-direction Replication - a bit of a pain just for a transfer. 2) Dump to a file, and load 3) Back-up Re-load Or I could just rebuild the entire thing. I would like to have the migration be as simple as possible, and am wondering what method is the best way to do that. Could someone please help? It would be greatly appreciated. Thanks in advance.
