PostgreSQL
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 5.14).
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.
