CREATE USER MAPPING(7)           SQL Commands           CREATE USER MAPPING(7)



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 con-
       nection 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
       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 spe-
              cific 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).
