I want to connect and use union to select data from all servers.
Here's an example of what I've done for 1 server only, I had an idea to use dblink(@server1/@server2.....@server5) and combine it with union.
I need to help to solve this.
SELECT
name, phonenumb, address, numb
FROM
bio
WHERE
numb_count = (SELECT MAX(numb_count) FROM audience)@server2
But it's not working.
Is there another way to solve this?
Regards.
