sql - 如何使用 SQL 在 IBM DB2 Z/OS 中显示表的当前权限

Question

是否有一种 SQL 方法可以显示 DB2 Z/OS 中表或 View 上的权限？我想实现这样的目标:

select * from sysibm.magic_table where table_name = 'users'

|TABLE_NAME|PRIVILEGE_TYPE|USER_OR_GROUP_NAME|
|     USERS|        INSERT|              ANDI|
|     USERS|        SELECT|            ADMINS|

那可能吗？

此查询告诉 grantee 中的用户/角色名称...auth 中的列和各种分配的权限列其中 Y = 现在，G = 正确的礼物和授予他人的权利。

SELECT
    grantee,
    screator,
    stname,
    tcreator,
    ttname,
    updatecols,
    alterauth,
    deleteauth,
    indexauth,
    insertauth,
    selectauth,
    updateauth
FROM
    SYSIBM.SYSTABAUTH
WHERE
    TTNAME = 'MY_TABLE'
    AND TCREATOR = 'MY_SCHEMA' 

样本结果集:
