不只是在一个表中，但我认为这是列出具有管理权限的用户的良好开端

SELECT
  distinct AUTHORIZATION_NAME
FROM QSYS2.USER_INFO cross
  join lateral (select * from table(systools.split(SPECIAL_AUTHORITIES,' '))) a
where element in ('*SECADM','*ALLOBJ')
union
SELECT
  user_name
FROM qsys2.function_usage
where function_id = 'QIBM_DB_SECADM'
  and usage = 'ALLOWED'
