Description

This statement creates the definition of a server for use with the Spider, FEDERATED or FederatedX storage engine. The CREATE SERVER statement creates a new row within the servers table within the mysql database. This statement requires the SUPER privilege.

The server_name should be a unique reference to the server. Server definitions are global within the scope of the server, it is not possible to qualify the server definition to a specific database. server_name has a maximum length of 64 characters (names longer than 64 characters are silently truncated), and is case insensitive. You may specify the name as a quoted string.

The wrapper_name should be mysql, and may be quoted with single quotes. Other values for wrapper_name are not currently supported.

For each option you must specify either a character literal or numeric literal. Character literals are UTF-8, support a maximum length of 64 characters and default to a blank (empty) string. String literals are silently truncated to 64 characters. Numeric literals must be a number between 0 and 9999, default value is 0.

Note: The OWNER option is currently not applied, and has no effect on the ownership or operation of the server connection that is created.

The CREATE SERVER statement creates an entry in the mysql.servers table that can later be used with the CREATE TABLE statement when creating a Spider, FederatedX or FEDERATED table. The options that you specify will be used to populate the columns in the mysql.servers table. The table columns are Server_name, Host, Db, Username, Password, Port and Socket.

DROP SERVER removes a previously created server definition.

CREATE SERVER is not written to the binary log, irrespective of the binary log format being used.

For valid identifiers to use as server names, see Identifier Names.

DROP SERVER IF EXISTS name;
CREATE SERVER server_name ...;

IF NOT EXISTS

Examples

CREATE SERVER s
FOREIGN DATA WRAPPER mysql
OPTIONS (USER 'Remote', HOST '192.168.1.106', DATABASE 'test');

OR REPLACE and IF NOT EXISTS:

CREATE SERVER s 
FOREIGN DATA WRAPPER mysql 
OPTIONS (USER 'Remote', HOST '192.168.1.106', DATABASE 'test');
ERROR 1476 (HY000): The foreign server, s, you are trying to create already exists

CREATE OR REPLACE SERVER s 
FOREIGN DATA WRAPPER mysql 
OPTIONS (USER 'Remote', HOST '192.168.1.106', DATABASE 'test');

CREATE SERVER IF NOT EXISTS s 
FOREIGN DATA WRAPPER mysql 
OPTIONS (USER 'Remote', HOST '192.168.1.106', DATABASE 'test');
