DROP FOREIGN TABLE
Name
DROP FOREIGN TABLE -- remove a foreign table
Synopsis
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 Section 5.13).
- 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 the 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.
