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

Examples

Drop the foreign tables named 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.
