Question

我想获取所有用户的列表以及在雪花中的单个查询中分配给这些用户的角色。

SHOW GRANTS TO ROLE1; --> This gives me list of all users assigned to ROLE1

但是我不能做下面的事情-

SHOW GRANTS TO ROLE1
UNION ALL
SHOW GRANTS TO ROLE2
UNION ALL
SHOW GRANTS TO ROLE3;

目标是在单个雪花查询中实现与上述类似的功能。

Answer 1

雪花中的许多查询不是真正的查询，因此您必须使用result_scan(-N)来执行额外的步骤来获取结果

show grants to ROLE accountadmin;

show grants to ROLE sysadmin;

select * from table(result_scan(-1))
union all
select * from table(result_scan(-2));

为我工作...

Answer 2

我写了一篇博客文章here，其中解释了如何获取角色层次结构（每个用户都是其成员的角色列表）和有效特权（所有授予类型的每个用户特权的完整列表）。我认为第一个查询可能更接近您想要的查询，但是我同时包括了这两个查询：

-- The data returned by both queries is in the
-- SNOWFLAKE database, which has latency of up
-- to 3 hours to reflect changes

-- Get the effective role hierarchy for each user.
with
   -- CTE gets all the roles each role is granted
   ROLE_MEMBERSHIPS(ROLE_GRANTEE, ROLE_GRANTED_THROUGH_ROLE)
   as
    (
    select   GRANTEE_NAME, "NAME"
    from     SNOWFLAKE.ACCOUNT_USAGE.GRANTS_TO_ROLES
    where    GRANTED_TO = 'ROLE' and
             GRANTED_ON = 'ROLE' and
             DELETED_ON is null
    ),
    -- CTE gets all roles a user is granted
    USER_MEMBERSHIPS(ROLE_GRANTED_TO_USER, USER_GRANTEE, GRANTED_BY)
    as
     (
     select ROLE,
            GRANTEE_NAME,
            GRANTED_BY
     from SNOWFLAKE.ACCOUNT_USAGE.GRANTS_TO_USERS
     where DELETED_ON is null
     )
-- 
select
        USER_GRANTEE,
        case
            when ROLE_GRANTED_THROUGH_ROLE is null
                then ROLE_GRANTED_TO_USER 
            else ROLE_GRANTED_THROUGH_ROLE
        end
        EFFECTIVE_ROLE,
        GRANTED_BY,
        ROLE_GRANTEE,
        ROLE_GRANTED_TO_USER,
        ROLE_GRANTED_THROUGH_ROLE
from    USER_MEMBERSHIPS U
    left join ROLE_MEMBERSHIPS R
        on U.ROLE_GRANTED_TO_USER = R.ROLE_GRANTEE
;

Answer 3

更简单的解决方案：

 SELECT  ROLE_NAME FROM SNOWFLAKE.INFORMATION_SCHEMA.APPLICABLE_ROLES
     START WITH GRANTEE in(select distinct ROLE from SNOWFLAKE.ACCOUNT_USAGE.GRANTS_TO_USERS GTU 
    join  SNOWFLAKE.ACCOUNT_USAGE.USERS u on u.name = GTU.grantee_name
        where GTU.DELETED_ON is NULL AND not U.DISABLED AND not
 U.SNOWFLAKE_LOCK and U.DELETED_ON is null and U.LOGIN_NAME ='USER' ) 
    CONNECT BY GRANTEE = PRIOR ROLE_NAME

查询以获取雪花中所有角色及其关联用户的列表
