Chris, take a look at Federated tables https://dev.mysql.com/doc/refman/5.5/en/federated-storage-engine.html
No, it is not as easy as Oracle's dblinks.

Subject: Calling function, that operates on another database

Hi all.

I have standard select statement and on one column I want to run
function, that will connect to another database (same server).
Is this possible?

High level example:

SELECT db1.clients.client_id, getTurnover(db1.clients.client_id) FROM
db1.clients;

AND getTurnover($id) body would be something like:

SELECT SUM(db2.turnover.amount) FROM db2.turnover WHERE
db2.turnover.client_id = $id;


So for some data, I need to make lookup to another database table.
Is this even possible?


Cheers, Chris.
