DROP VIEW

DROP VIEW forcibly deletes an existing view in a database.

Only a view owner or a system administrator can run DROP VIEW command.

Be cautious when using DROP OBJECT (e.g., DATABASE, USER/ROLE, SCHEMA, TABLE, VIEW) as it may cause data loss, especially with CASCADE deletions. Always back up data before proceeding.
For more information about development and design specifications, see "GaussDB(DWS) Development and Design Proposal" in the Data Warehouse Service (DWS) Developer Guide.

1
DROP VIEW [ IF EXISTS ] view_name [, ...] [ CASCADE | RESTRICT ];

IF EXISTS
Sends a notice instead of an error if the specified view does not exist.
view_name
Specifies the name of the view to be deleted.

Value range: An existing view.
CASCADE | RESTRICT
- CASCADE: deletes objects (such as other views) that depend on a view to be deleted.
- RESTRICT: refuses to delete the view if any objects depend on it. This is the default.
