In the previous list of articles, I demonstrated FEDERATED storage engine to perform cross-server queries between MySQL Servers.

MySQL: Create FEDERATED Table to SELECT data from another server (Part 3/4)

In this post, I am showing to create the Connection Server and use that Server detail with multiple FEDERATED Table of MySQL.

Without a Connection server, we need to write the connection string in every FEDERATED table so when we have a multiple FEDERATED table and which are using same remote connection information, create Connection Server once and use with all tables.

Below is a small demonstration.

First Create a Server:

CREATE SERVER FederatedConnectionServer
FOREIGN DATA WRAPPER mysql
OPTIONS (USER 'UserName',password 'Password', HOST 'localhost', PORT 3306, DATABASE 'TestDB');

Now use this server information to create Remote FEDERATED Table:

CREATE TABLE tbl_RemoteTable 
(
    ID integer
    ,Name VARCHAR(255)
) 
ENGINE=FEDERATED
CONNECTION='FederatedConnectionServer/tbl_RemoteTable';
