NAME

DROP VIEW − Removes an existing view from a database

SYNOPSIS

DROP VIEW name

INPUTS

name

The name of an existing view.

OUTPUTS

DROP

The message returned if the command is successful.

ERROR: RewriteGetRuleEventRel: rule "_RETname" not found

This message occurs if the specified view does not exist in the database.

DESCRIPTION

DROP VIEW drops an existing view from the database. To execute this command you must be the owner of the view.

NOTES
The Postgres DROP TABLE statement also drops views.

Refer to CREATE VIEW for information on how to create views.

USAGE

This command will remove the view called kinds:

DROP VIEW kinds;

COMPATIBILITY

SQL92
SQL92 specifies some additional capabilities for DROP VIEW:

DROP VIEW view { RESTRICT | CASCADE }

INPUTS
RESTRICT

Ensures that only a view with no dependent views or integrity constraints can be destroyed.

CASCADE

Any referencing views and integrity constraints will be dropped as well.

NOTES
At present, to remove a referenced view from a Postgres database, you must drop it explicitly.
