DROP SEQUENCE
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.
Compatibility
DROP SEQUENCE conforms to theSQL standard, except that the standard only allows one sequence to be dropped per command, and apart from theIF EXISTS option, which is aPostgreSQL extension.
