# DROP FOREIGN TABLE

### DROP FOREIGN TABLE

DROP FOREIGN TABLE — remove a foreign table

### Synopsis

```

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

### Description

`DROP FOREIGN TABLE` removes a foreign table. Only the owner of a foreign table can remove it.

### Parameters

`IF EXISTS` : Do not throw an error if the foreign table does not exist. A notice is issued in this case.

*`name`* : The name (optionally schema-qualified) of the foreign table to drop.

`CASCADE` : Automatically drop objects that depend on the foreign table (such as views), and in turn all objects that depend on those objects (see [Section 5.15](/the-sql-language/ddl/ddl-depend.md)).

`RESTRICT` : Refuse to drop the foreign table if any objects depend on it. This is the default.

### Examples

To destroy two foreign tables, `films` and `distributors`:

```

DROP FOREIGN TABLE films, distributors;
```

### Compatibility

This command conforms to ISO/IEC 9075-9 (SQL/MED), except that the standard only allows one foreign table to be dropped per command, and apart from the `IF EXISTS` option, which is a PostgreSQL extension.

# 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 dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.postgresql.tw/reference/sql-commands/sql-dropforeigntable.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
