DROP FOREIGN TABLE

7 SQL - Language Statements

DROP FOREIGN TABLE

remove a foreign table

    DROP FOREIGN TABLE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]

## Description

`DROP FOREIGN TABLE` removes a foreign table. Only the owner of a foreign table can remove it.

## Parameters

`IF EXISTS`

- Do not throw an error if the foreign table does not exist. A notice is issued in this case.

`name`

- The name (optionally schema-qualified) of the foreign table to drop.

`CASCADE`

- Automatically drop objects that depend on the foreign table (such as views), and in turn all objects that depend on those objects (see ddl-depend).

`RESTRICT`

- Refuse to drop the foreign table if any objects depend on it. This is the default.

## Examples

To destroy two foreign tables, `films` and `distributors`:

    DROP FOREIGN TABLE films, distributors;

## Compatibility

This command conforms to ISO/IEC 9075-9 (SQL/MED), except that the standard only allows one foreign table to be dropped per command, and apart from the `IF EXISTS` option, which is a PostgreSQL extension.
