DROP SCHEMA
DROP SCHEMA
DROP SCHEMA - remove 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 a schema.
-
CASCADE -
Automatically drop objects (tables, functions, etc.) that are contained in the schema, and in turn all objects that depend on those objects (see Section 5.14 ).
-
RESTRICT -
Refuse to drop the schema if it contains any objects. This is the default.
Notes
Using the
CASCADE
option might make the command
remove objects in other schemas besides the one(s) named.
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, and apart from the
IF EXISTS
option, which is a
PostgreSQL
extension.
