 "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 5.13).




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.
