DROP SEQUENCE

Name

DROP SEQUENCE  --  remove a sequence

Synopsis

DROP SEQUENCE name [, ...] [ CASCADE | RESTRICT ]

  

Inputs

name

The name (optionally schema-qualified) of a sequence.

CASCADE

Automatically drop objects that depend on the sequence.

RESTRICT

Outputs

DROP SEQUENCE

Description

DROP SEQUENCE removes sequence number generators from the data base. With the current implementation of sequences as special tables it works just like the DROP TABLE statement.

The DROP SEQUENCE statement is a PostgreSQL language extension.

Refer to the CREATE SEQUENCE statement for information on how to create a sequence.

Usage

To remove sequence serial from database:

DROP SEQUENCE serial;
   

Compatibility
