DROP SEQUENCE

Removes a sequence.

Synopsis

DROP SEQUENCE [IF EXISTS] <name> [, ...] [CASCADE | RESTRICT]

Description

DROP SEQUENCE removes sequence number generators. You must own the sequence to drop it (or be a superuser).

Parameters

IF EXISTS: Do not throw an error if the sequence does not exist. Greenplum Database issues a notice in this case.
name: The name (optionally schema-qualified) of the sequence to remove.
CASCADE: Automatically drop objects that depend on the sequence, and in turn all objects that depend on those objects.
RESTRICT: Refuse to drop the sequence if any objects depend on it. This is the default.

Examples

Remove the sequence myserial:

DROP SEQUENCE myserial;

Compatibility

DROP SEQUENCE conforms to the SQL standard, except that the standard allows only one sequence to be dropped per command. Also, the IF EXISTS option is a Greenplum Database extension.
