从补丁 198 开始，Amazon Redshift 将不再支持创建新的 Python UDF。现有的 Python UDF 将继续正常运行至 2026 年 6 月 30 日。有关更多信息，请参阅[博客文章](https://aws.amazon.com/blogs/big-data/amazon-redshift-python-user-defined-functions-will-reach-end-of-support-after-june-30-2026/)。

# SVV\$1IDENTITY\$1PROVIDERS
<a name="r_SVV_IDENTITY_PROVIDERS"></a>

SVV\$1IDENTITY\$1PROVIDERS 视图返回身份提供商的名称和其他属性。有关如何创建身份提供商角色的更多信息，请参阅 [CREATE IDENTITY PROVIDER](r_CREATE_IDENTITY_PROVIDER.md)。

SVV\$1IDENTITY\$1PROVIDERS 只对超级用户可见。有关更多信息，请参阅 [系统表和视图中的数据可见性](cm_chap_system-tables.md#c_visibility-of-data)。

### 示例查询
<a name="SVV_IDENTITY_PROVIDERS-sample-queries"></a>

要查看身份提供商属性，请在创建身份提供商之后，运行类似以下内容的查询。

```
SELECT name, type, instanceid, namespc, params, enabled 
FROM svv_identity_providers 
ORDER BY 1;
```

示例输出包括 Microsoft Entra ID（以前称作 Azure AD）的参数描述：

```
       name       | type  |              instanceid              | namespc |                                                                                                                                                params                                                                                                                                                 | enabled
