DROP SEQUENCE(7)                 PostgreSQL 9.2.24 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.

       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.

SEE ALSO
       CREATE SEQUENCE (CREATE_SEQUENCE(7)), ALTER SEQUENCE (ALTER_SEQUENCE(7))
