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 5.14).
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.
