SYNOPSIS
DROP SEQUENCE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]
DESCRIPTION
-
Note
At present, this section is just taken from PostgreSQL documentation and is subject to revision for Postgres-XC.
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.
