DROP FOREIGN TABLE

Removes a foreign table.

Synopsis

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

Description

DROP FOREIGN TABLE removes an existing 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. Greenplum Database issues a notice 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.
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

DROP FOREIGN TABLE conforms to ISO/IEC 9075-9 (SQL/MED), except that the standard only allows one foreign table to be dropped per command. The IF EXISTS clause is a Greenplum Database extension.
