Removes a sequence.

Synopsis

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

Description

DROP SEQUENCE removes a sequence generator table. 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. A notice is issued in this case.
name
The name (optionally schema-qualified) of the sequence to remove.
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

Remove the sequence myserial:

DROP SEQUENCE myserial;

Compatibility

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