NAME
CREATE USER MAPPING - define a new mapping of a user to a foreign
server
SYNOPSIS
CREATE USER MAPPING FOR { username | USER | CURRENT_USER | PUBLIC }
SERVER servername
[ OPTIONS ( option ’value’ [ , ... ] ) ]
DESCRIPTION
CREATE USER MAPPING defines a mapping of a user to a foreign server. A
user mapping typically encapsulates connection information that a
foreign-data wrapper uses together with the information encapsulated be
a foreign server to access an external data resource.
The owner of a foreign server can create user mappings for that server
for any user. Also, a user can create a user mapping for his own user
name if USAGE privilege on the server has been granted to the user.
PARAMETERS
username
The name of an existing user that is mapped to foreign server.
CURRENT_USER and USER match the name of the current user. When
PUBLIC is specified, a so-called public mapping is created that
is used when no user-specific mapping is applicable.
servername
The name of an existing server for which the user mapping is to
be created.
OPTIONS ( option ’value’ [, ... ] )
This clause specifies the options of the user mapping. The
options typically define the actual user name and password of
the mapping. Option names must be unique. The allowed option
names and values are specific to the server’s foreign-data
wrapper.
EXAMPLES
Create a user mapping for user bob, server foo:
CREATE USER MAPPING FOR bob SERVER foo OPTIONS (user ’bob’, password ’secret’);
COMPATIBILITY
CREATE USER MAPPING conforms to ISO/IEC 9075-9 (SQL/MED).
