DROP SEQUENCE(7) PostgreSQL 16.9 Documentation DROP SEQUENCE(7)
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, and in turn
all objects that depend on those objects (see Section 5.14).
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.
