DROP SEQUENCE

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.
