This statement creates the definition of a server for use with the FEDERATED
storage engine. The CREATE SERVER
statement creates a new row in the servers
table in the mysql
database. This statement
requires the SUPER
privilege.
The
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. server_name
The
should be wrapper_name
mysql
, and may be quoted with single quotation marks. Other values for
are not currently supported.
wrapper_name
For each
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.option
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 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
.
For example:
CREATE SERVER sFOREIGN DATA WRAPPER mysqlOPTIONS (USER 'Remote', HOST '192.168.1.106', DATABASE 'test');
Be sure to specify all options necessary to establish a connection to the server. The user name, host name, and database name are mandatory. Other options might be required as well, such as password.
The data stored in the table can be used when creating a connection to a FEDERATED
table:
CREATE TABLE t (s1 INT) ENGINE=FEDERATED CONNECTION='s';
For more information, see Section 14.9, "The FEDERATED
Storage Engine".
CREATE SERVER
causes an automatic commit.
In MySQL 5.6, CREATE SERVER
is not written to the binary log, regardless of the
logging format that is in use.
In MySQL 5.6.11 only, gtid_next
must be set to AUTOMATIC
before issuing
this statement. (Bug #16062608, Bug #16715809, Bug #69045)
