IMPORT FOREIGN SCHEMA(7)                        PostgreSQL 9.5.0 Documentation


NAME

       IMPORT_FOREIGN_SCHEMA - import table definitions from a foreign server


SYNOPSIS

       IMPORT FOREIGN SCHEMA remote_schema
           [ { LIMIT TO | EXCEPT } ( table_name [, ...] ) ]
           FROM SERVER server_name
           INTO local_schema
           [ OPTIONS ( option 'value' [, ... ] ) ]


DESCRIPTION

       IMPORT FOREIGN SCHEMA creates foreign tables that represent tables
       existing on a foreign server. The new foreign tables will be owned by
       the user issuing the command and are created with the correct column
       definitions and options to match the remote tables.

       By default, all tables and views existing in a particular schema on the
       foreign server are imported. Optionally, the list of tables can be
       limited to a specified subset, or specific tables can be excluded. The
       new foreign tables are all created in the target schema, which must
       already exist.

       To use IMPORT FOREIGN SCHEMA, the user must have USAGE privilege on the
       foreign server, as well as CREATE privilege on the target schema.


PARAMETERS

       remote_schema
           The remote schema to import from. The specific meaning of a remote
           schema depends on the foreign data wrapper in use.

       LIMIT TO ( table_name [, ...] )
           Import only foreign tables matching one of the given table names.
           Other tables existing in the foreign schema will be ignored.

       EXCEPT ( table_name [, ...] )
           Exclude specified foreign tables from the import. All tables
           existing in the foreign schema will be imported except the ones
           listed here.

       server_name
           The foreign server to import from.

       local_schema
           The schema in which the imported foreign tables will be created.

       OPTIONS ( option 'value' [, ...] )
           Options to be used during the import. The allowed option names and
           values are specific to each foreign data wrapper.


EXAMPLES

       Import table definitions from a remote schema foreign_films on server
       film_server, creating the foreign tables in local schema films:

           IMPORT FOREIGN SCHEMA foreign_films
               FROM SERVER film_server INTO films;

       As above, but import only the two tables actors and directors (if they
       exist):

           IMPORT FOREIGN SCHEMA foreign_films LIMIT TO (actors, directors)
               FROM SERVER film_server INTO films;


COMPATIBILITY

       The IMPORT FOREIGN SCHEMA command conforms to the SQL standard, except
       that the OPTIONS clause is a PostgreSQL extension.
