# DROP VIEW

DROP VIEW — 移除檢視表

### 語法

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

### 說明

DROP VIEW 移除現有檢視表。要執行此命令，您必須是檢視表的擁有者。

### 參數

`IF EXISTS`

如果檢視表不存在，請不要拋出錯誤。在這種情況下發出 NOTICE。

*`name`*

要移除的檢視表名稱（可選擇性加上綱要名稱）。

`CASCADE`

自動移除相依於檢視表的物件（例如其他檢視表），以及相依於這些物件的所有物件（參閱[第 5.13 節](/15/the-sql-language/ddl/dependency-tracking.md)）。

`RESTRICT`

如果任何物件相依於它，則拒絕移除檢視表。這是預設行為。

### 範例

此指令將移除名稱為 kinds 的檢視表：

```
DROP VIEW kinds;
```

### 相容性

此命令符合 SQL 標準，但標準僅允許每個指令移除一個檢視表，並且除了 IF EXISTS 選項（PostgreSQL 延伸功能）之外。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.postgresql.tw/15/reference/sql-commands/drop-view.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
