DROP SEQUENCE
Name
DROP SEQUENCE -- remove a sequence
Synopsis
DROP SEQUENCE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]
Description
DROP SEQUENCE removes sequence number generators. A sequence can only be dropped by its owner or a superuser.
Parameters
- IF EXISTS
-
Do not throw an error if the sequence does not exist. A notice is issued in this case.
- name
-
The name (optionally schema-qualified) of a sequence.
- CASCADE
-
Automatically drop objects that depend on the sequence.
- RESTRICT
-
Refuse to drop the sequence if any objects depend on it. This is the default.
Examples
To remove the sequence serial:
DROP SEQUENCE serial;
Compatibility
DROP SEQUENCE conforms to the SQL standard, except that the standard only allows one sequence to be dropped per command, and apart from the IF EXISTS option, which is a PostgreSQL extension.
