Snowflake cloud data platform 查询以获取雪花中所有角色及其关联用户的列表

我想在snowflake中的单个查询中获得所有用户的列表以及分配给这些用户的角色

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

但我不能做下面这样的事情-

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上述功能

问候,，

snowflake中的许多查询都不是真正的查询，因此您必须在额外的步骤中使用result\u scan-N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));

我写了一篇博文，解释了如何获取每个用户都是其成员的角色的角色层次结构列表和有效权限，以及所有授予类型的每个用户的完整权限列表。我认为第一个查询可能更接近您想要的内容，但我同时包括以下两个方面：

-- 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,

    left join ROLE_MEMBERSHIPS R

    )
select * from EFFECTIVE_ROLES R
    left join GRANT_LIST G 
        on G.GRANTED_TO = R.EFFECTIVE_ROLE
where G.PRIVILEGE is not null

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
