如何检查谁有权访问 SQL Server 中的对称密钥

Question

我想知道所有有权访问对称密钥的用户以及他们拥有的访问类型。你能让我知道我该怎么做吗？

Answer 1

上面的答案实际上并不反映对象名称，请考虑以下内容：

select
      [database] = db_name()
    , u.name
    , p.permission_name
    , p.class
    , p.class_desc
    , ObjectNameForObjectORColumn
        = object_name(p.major_id) 
    , objectNameActual
        = case class_desc
            when 'SYMMETRIC_KEYS' then sm.name              
            when 'CERTIFICATE' then [cert].name             
      end
    , state_desc 
from sys.database_permissions  p 
inner join sys.database_principals u
    on p.grantee_principal_id = u.principal_id
left outer join sys.symmetric_keys sm
    on p.major_id = sm.symmetric_key_id
    and p.class_desc = 'SYMMETRIC_KEYS'
left outer join sys.certificates [cert]
    on p.major_id = [cert].[certificate_id]
    and p.class_desc = 'CERTIFICATE'
where class_desc in('SYMMETRIC_KEYS', 'CERTIFICATE')
order by u.name
