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
MONITOR、OPERATE 或 OWNERSHIP	警报	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.

有关创建具有指定权限集的自定义角色的说明，请参阅创建自定义角色。

有关对安全对象执行 SQL 操作的相应角色和权限授予的一般信息，请参阅访问控制概述。

使用说明¶

仅返回警报所有者（即对警报具有 OWNERSHIP 权限的角色）或对警报具有 OPERATE 权限的角色的行。

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.

For example, you can use the pipe operator or RESULT_SCAN function to select specific columns from the SHOW command output or filter the rows.

When you refer to the output columns, use double-quoted identifiers for the column names. For example, to select the output column type, specify SELECT "type".

You must use double-quoted identifiers because the output column names for SHOW commands are in lowercase. The double quotes ensure that the column names in the SELECT list or WHERE clause match the column names in the SHOW command output that was scanned.
