SEQUENCE
Name
DROP SEQUENCE -- remove a sequence
Synopsis
DROP SEQUENCE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]
Description
DROP SEQUENCE removes sequence number
generators.
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

sequence.

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.
