DROP SCHEMA

Removes a schema.

Synopsis

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

Description

DROP SCHEMA removes schemas from the database. A schema can only be dropped by its owner or a superuser. Note that the owner can drop the schema (and thereby all contained objects) even if they do not own some of the objects within the schema.

Parameters

  • IF EXISTS: Do not throw an error if the schema does not exist. A notice is issued in this case.

  • name: The name of the schema to remove.

  • CASCADE: Automatically drops any objects contained in the schema (tables, functions, etc.).

  • RESTRICT: Refuse to drop the schema if it contains any objects. This is the default.

Examples

Remove the schema mystuff from the database, along with everything it contains:

DROP SCHEMA mystuff CASCADE;

Compatibility

DROP SCHEMA is fully conforming with the SQL standard, except that the standard only allows one schema to be dropped per command. Also, the IF EXISTS option is a Greenplum Database extension.
