Question

我想知道有权访问对称密钥的所有用户以及他们拥有的访问类型。你能告诉我怎么做吗？

Answer 1

上面的答案实际上并不反映对象名称，请改为考虑：

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

Answer 2

也许这个查询可以提供帮助：

select u.name, p.permission_name, p.class_desc, 
    object_name(p.major_id) ObjectName, state_desc 
from sys.database_permissions  p join sys.database_principals u
on p.grantee_principal_id = u.principal_id
where class_desc = 'SYMMETRIC_KEYS'

Answer 3

这个改进的查询提供了当前数据库的名称，以避免错误。此外，如果你使用SYMMETRIC KEYS，通常你也使用证书，那么为什么这也是查看CERTIFICATE权限的好选择：

select db_name(), u.name, p.permission_name, p.class_desc, 
    object_name(p.major_id) ObjectName, state_desc 
from sys.database_permissions  p join sys.database_principals u
    on p.grantee_principal_id = u.principal_id
    where class_desc in('SYMMETRIC_KEYS', 'CERTIFICATE')
order by u.name
