AW: replication on single server
The thing is that this particular table in database 'A' contains bounceback email addresses, all other databases are customer databases containing pretty large subscriber tables. Now I need to find matches between this bounceback table and all other customer subscriber tables. So I'd like to do a join over these, which is not possible because they reside in different databases (Like SELECT s.name FROM bouncebacks b, subcriber s where s.email = b.email). So if I could replicate this table, I could perform the above join. right now I find matches between the bounceback and the subscriber list by scripting, which is slooow - with ca. 10,000 bouncebacks and say up to 15,000 subscribers/customer. I don't really like this concept, but I can't think of a better one... Thanks again for suggestions! Tom -Ursprüngliche Nachricht- Von: Paul DuBois [mailto:[EMAIL PROTECTED] Gesendet: Freitag, 14.

Re: AW: replication on single server
Hi, With MySQL, you can join tables that are in different databases as long as they are on the same server. In your case, you could run: SELECT s.name FROM A.bouncebacks b, subcriber s where s.email = b.email Regards, Joseph Bueno Brandl, Thomas wrote: The thing is that this particular table in database 'A' contains bounceback email addresses, all other databases are customer databases containing pretty large subscriber tables.

replication on single server
Hey guys, Simply said, imagine this scenario: A MySQL server with about 10 databases: A and 1 to 9. Database A contains a 'special' table that is supposed to be replicated to all other databases on the same machine, so it is kinda like the master database. So how do I tell MySQL which databases I consider to be slaves and master?? Thanks very mouch for your help!

Re: replication on single server
Databases are neither slave nor master, servers are. A master may have many slaves, but a slave may have only one master.
