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.
