select dp.NAME AS principal_name,
       dp.type_desc AS principal_type_desc,
       o.NAME AS object_name,
       p.permission_name,
       p.state_desc AS permission_state_desc
from   sys.database_permissions p
left   OUTER JOIN sys.all_objects o
on     p.major_id = o.OBJECT_ID
inner  JOIN sys.database_principals dp
on     p.grantee_principal_id = dp.principal_id

如果您只想获取一个数据库的用户和角色分配列表，您可以这样做。这适用于 Azure SQL。

select P.Name, R.Name
from sys.database_principals P 
left outer join sys.database_role_members RM on P.principal_id=RM.member_principal_id 
left outer join sys.database_principals R on R.principal_id=RM.role_principal_id

如果您正在寻找服务器角色，请使用以下命令：

select
    u.name [user],
    r.name [role]
from 
    sys.server_principals u
    join sys.server_role_members rm 
        on u.principal_id = rm.member_principal_id
        and u.type in ('S')
    join sys.server_principals r 
        on r.principal_id = rm.role_principal_id
        and r.type in ('R')
