NAME

       CREATE_USER_MAPPING - define a new mapping of a user to a foreign server

SYNOPSIS

       CREATE USER MAPPING FOR { user_name | USER | CURRENT_USER | PUBLIC }
           SERVER server_name
           [ 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 by 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

       user_name
           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.

       server_name
           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).
