Synopsis
DROP TABLE name [, ...] [ CASCADE | RESTRICT ]
Inputs
- name

- CASCADE
Automatically drop objects that depend on the table
(such as views).
- RESTRICT
Refuse to drop the table if there are any dependent objects.
This is the default.

The message returned if the command completes successfully.

Description
DROP TABLE removes tables from the database.
Only its owner may destroy a table. A table may be emptied of rows, but not
destroyed, by using DELETE.
DROP TABLE always removes any indexes, rules,
triggers, and constraints that exist for the target table. However,
to drop a table that is referenced by a foreign-key constraint of another
table, CASCADE must be specified. (CASCADE will remove the foreign-key
constraint, not the other table itself.)
Notes
Refer to CREATE TABLE and
ALTER TABLE for information on
how to create or modify tables.
Usage
To destroy two tables, films and
distributors:
DROP TABLE films, distributors;
