# 35.25. enabled\_roles \#

檢視表 `enabled_roles` 列出目前「已啟用的角色」。已啟用的角色會以遞迴方式 定義為目前使用者，以及所有已透過自動繼承授與已啟用角色的角色。換言之，這些是 目前使用者直接或間接具有自動繼承成員資格的所有角色。

權限檢查使用的是「適用角色」集合，其範圍可能比已啟用角色集合更廣。因此通常 建議使用檢視表 `applicable_roles`，而非此檢視表；`applicable_roles` 檢視表的 詳細資訊請參閱[第 35.5 節](/client-interfaces/information-schema/infoschema-applicable-roles.md)。

# 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/client-interfaces/information-schema/infoschema-enabled-roles.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.
