如何使用SQL在IBM DB2 Z / OS中显示表的当前特权

Question

是否有一种SQL方法来显示DB2 Z / OS中表或视图上的特权？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|

这可能吗？

此查询告知grantee列中的用户/角色名称以及...auth列中Y =正确存在，G =正确存在的各个已分配的权限并有权将其授予他人。

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

示例结果集：
