访问控制要求¶
用于执行此 SQL 命令的 角色 必须至少具有以下 一项 权限：
权限 |
对象 |
备注 |
|---|---|---|
APPLY AUTHENTICATION POLICY |
账户 |
Only the SECURITYADMIN role, or a higher role, has this privilege by default. The privilege can be granted to additional roles as needed. |
OWNERSHIP |
身份验证策略 |
OWNERSHIP is a special privilege on an object that is automatically granted to the role that created the object, but can also be transferred using the GRANT OWNERSHIP command to a different role by the owning role (or any role with the MANAGE GRANTS privilege). |
The USAGE privilege on the parent database and schema are required to perform operations on any object in a schema. Note that a role granted any privilege on a schema allows that role to resolve the schema. For example, a role granted CREATE privilege on a schema can create objects on that schema without also having USAGE granted on that schema.

使用说明¶
To post-process the output of this command, you can use the pipe operator (
->>) or the RESULT_SCAN function. Both constructs treat the output as a result set that you can query.The output column names for this command are generated in lowercase. If you consume a result set from this command with the pipe operator or the RESULT_SCAN function, use double-quoted identifiers for the column names in the query to ensure that they match the column names in the output that was scanned. For example, if the name of an output column is
type, then specify"type"for the identifier.
示例¶
描述名为 my_auth_policy 的身份验证策略：
