NAME

       CREATE_FOREIGN_TABLE - define a new foreign table

SYNOPSIS

       CREATE FOREIGN TABLE [ IF NOT EXISTS ] table_name ( [
         { column_name data_type [ NULL | NOT NULL ] }
           [, ... ]
       ] )
         SERVER server_name
       [ OPTIONS ( option 'value' [, ... ] ) ]

DESCRIPTION

       CREATE FOREIGN TABLE will create a new foreign table in the current
       database. The table will be owned by the user issuing the command.

       If a schema name is given (for example, CREATE FOREIGN TABLE
       myschema.mytable ...) then the table is created in the specified
       schema. Otherwise it is created in the current schema. The name of the
       foreign table must be distinct from the name of any other foreign
       table, table, sequence, index, or view in the same schema.

       CREATE FOREIGN TABLE also automatically creates a data type that
       represents the composite type corresponding to one row of the foreign
       table. Therefore, foreign tables cannot have the same name as any
       existing data type in the same schema.

PARAMETERS

       IF NOT EXISTS
           Do not throw an error if a relation with the same name already
           exists. A notice is issued in this case. Note that there is no
           guarantee that the existing relation is anything like the one that
           would have been created.

       table_name
           The name (optionally schema-qualified) of the table to be created.

       column_name
           The name of a column to be created in the new table.

       data_type
           The data type of the column. This can include array specifiers. For
           more information on the data types supported by PostgreSQL, refer
           to Chapter 8, Data Types, in the documentation.

       NOT NULL
           The column is not allowed to contain null values.

       NULL
           The column is allowed to contain null values. This is the default.

           This clause is only provided for compatibility with non-standard
           SQL databases. Its use is discouraged in new applications.

       server_name
           The name of an existing server for the foreign table.

       OPTIONS ( option 'value' [, ...] )
           Options to be associated with the new foreign table. The allowed
           option names and values are specific to each foreign data wrapper
           and are validated using the foreign-data wrapper's validator
           function. Option names must be unique.

EXAMPLES

       Create foreign table films with film_server:

           CREATE FOREIGN TABLE films (
               code        char(5) NOT NULL,
               title       varchar(40) NOT NULL,
               did         integer NOT NULL,
               date_prod   date,
               kind        varchar(10),
               len         interval hour to minute
           )
           SERVER film_server;

COMPATIBILITY

       The CREATE FOREIGN TABLE command largely conforms to the SQL standard;
       however, much as with CREATE TABLE, NULL constraints and zero-column
       foreign tables are permitted.
