is set to the value of an empty string, since get_field would set it to

column is NOT NULL.

DESCRIPTION
Populates the share with information about the connection
to the foreign database that will serve as the data source.
This string must be specified (currently) in the "comment" field,
This string must be specified (currently) in the "CONNECTION" field,
listed in the CREATE TABLE statement.
This string MUST be in the format of any of these:
scheme://username:password@hostname:port/database/table
scheme://username@hostname/database/table
scheme://username@hostname:port/database/table
scheme://username:password@hostname/database/table
CONNECTION="scheme://username:password@hostname:port/database/table"
CONNECTION="scheme://username@hostname/database/table"
CONNECTION="scheme://username@hostname:port/database/table"
CONNECTION="scheme://username:password@hostname/database/table"
_OR_
CONNECTION="connection name"
An Example:
mysql://joe:joespass@192.168.1.111:9308/federated/testtable
CREATE TABLE t1 (id int(32))
ENGINE="FEDERATED"
CONNECTION="mysql://joe:joespass@192.168.1.111:9308/federated/testtable";
CREATE TABLE t2 (
id int(4) NOT NULL auto_increment,
name varchar(32) NOT NULL,
PRIMARY KEY(id)
) ENGINE="FEDERATED" CONNECTION="my_conn";
***IMPORTANT***
Currently, only "mysql://" is supported.
Currently, the Federated Storage Engine only supports connecting to another
MySQL Database ("scheme" of "mysql"). Connections using JDBC as well as
other connectors are in the planning stage.
'password' and 'port' are both optional.
