NAME
DROP SCHEMA - remove a schema
SYNOPSIS
DROP SCHEMA 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 he does not own some of the objects within the schema.
PARAMETERS
- name
- The name of a schema.
- CASCADE
- Automatically drop objects (tables, functions, etc.) that are contained in the schema.
- RESTRICT
- Refuse to drop the schema if it contains any objects. This is the default.
EXAMPLES
To remove 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.
