DROP VIEW

DROP VIEW — 删除一个视图

DROP VIEW — remove a view

Synopsis

DROP VIEW [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]

Description

DROP VIEW 删除一个现有视图。要执行该命令，您必须是该视图的所有者。

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

Parameters

IF EXISTS
- Do not throw an error if the view does not exist. A notice is issued in this case.
name
- The name (optionally schema-qualified) of the view to remove.
CASCADE
- Automatically drop objects that depend on the view (such as other views), and in turn all objects that depend on those objects (see Section 5.14).
RESTRICT
- Refuse to drop the view if any objects depend on it. This is the default.

Examples

该命令将删除名为 kinds 的视图：

This command will remove the view called kinds:

DROP VIEW kinds;

Compatibility

此命令符合 SQL 标准，但该标准只允许每个命令删除一个视图，除了 IF EXISTS 选项，它是 PostgreSQL 扩展。

This command conforms to the SQL standard, except that the standard only allows one view to be dropped per command, and apart from the IF EXISTS option, which is a PostgreSQL extension.
