SQL - Language Statements
CREATE SERVER
define a new foreign server
CREATE SERVER
CREATE SERVER servername [ TYPE 'servertype' ] [ VERSION 'serverversion' ]
FOREIGN DATA WRAPPER fdwname
[ OPTIONS ( option 'value' [, ... ] ) ]
Description
CREATE SERVER defines a new foreign server. The
user who defines the server becomes its owner.
A foreign server typically encapsulates connection information that
a foreign-data wrapper uses to access an external data resource.
Additional user-specific connection information may be specified by
means of user mappings.
The server name must be unique within the database.
Creating a server requires USAGE> privilege on the
foreign-data wrapper being used.
Parameters
servername
The name of the foreign server to be created.
servertype
Optional server type.
serverversion
Optional server version.
fdwname
The name of the foreign-data wrapper that manages the server.
OPTIONS ( option 'value' [, ... ] )
This clause specifies the options for the server. The options
typically define the connection details of the server, but the
actual names and values are dependent on the server's
foreign-data wrapper.
Notes
When using the dblink module
(see ), the foreign server name can be used
as an argument of the
function to indicate the connection parameters. See also there for
more examples. It is necessary to have
the USAGE privilege on the foreign server to be
able to use it in this way.
Examples
Create a server foo> that uses the built-in foreign-data
wrapper default>:
CREATE SERVER foo FOREIGN DATA WRAPPER "default";
Create a server myserver> that uses the
foreign-data wrapper pgsql>:
CREATE SERVER myserver FOREIGN DATA WRAPPER pgsql OPTIONS (host 'foo', dbname 'foodb', port '5432');
Compatibility
CREATE SERVER conforms to ISO/IEC 9075-9 (SQL/MED).
