Tsql SQL Server-从孤立用户SID获取数据库角色成员身份

我目前正在SQL Server 2005中使用以下代码来获取孤立用户SID的数据，这很有效，但我确实需要获取每个孤立用户SID的角色成员身份信息，这是否可行？如果可能，我如何为此编写查询

DECLARE cur CURSOR FAST_FORWARD FOR 
SELECT name FROM sys.databases 
WHERE database_id > 4 

OPEN cur  

DECLARE @SQL NVARCHAR(MAX), @DBName SYSNAME 
DECLARE @Results TABLE (DBName SYSNAME, UserName SYSNAME, UserSID VARBINARY(MAX))  

FETCH NEXT FROM cur into @DBName  

WHILE @@FETCH_STATUS = 0 
BEGIN 
    SET @SQL = 'USE ' + @DBName + ';SELECT ''' + @DBName + ''' AS DBName, 
            UserName = name, UserSID = sid from sysusers 
            WHERE issqluser = 1 AND 
                (sid IS NOT NULL AND sid <> 0x0) AND 
                (LEN(sid) <= 16) AND SUSER_SNAME(sid) IS NULL'     

    INSERT INTO @Results 
    EXEC(@SQL)

    FETCH NEXT FROM cur into @DBName  
END  

CLOSE cur 
DEALLOCATE cur  

SELECT * FROM @Results

它选择用户成员资格

select case when SUSER_SNAME( dp.sid ) is null then dp.name else SUSER_SNAME( dp.sid ) end 'dbUser',
dp2.name 'dbRole', dp.type_desc uDesc
from sys.database_principals dp left join sys.database_role_members dr 
on dr.member_principal_id = dp.principal_id
left join sys.database_principals dp2 on dr.role_principal_id = dp2.principal_id
where dp.type_desc <> 'DATABASE_ROLE'
and case when SUSER_SNAME( dp.sid ) is null then dp.name else SUSER_SNAME( dp.sid ) end
not in ('sys', 'INFORMATION_SCHEMA', 'guest')
order by 1

我想我就快到了，我已经建立了相关的查询，希望能把相关的ID和角色拉过来。

select case when SUSER_SNAME( dp.sid ) is null then dp.name else SUSER_SNAME( dp.sid ) end 'dbUser',
dp2.name 'dbRole', dp.type_desc uDesc
from sys.database_principals dp left join sys.database_role_members dr 
on dr.member_principal_id = dp.principal_id
left join sys.database_principals dp2 on dr.role_principal_id = dp2.principal_id
where dp.type_desc <> 'DATABASE_ROLE'
and case when SUSER_SNAME( dp.sid ) is null then dp.name else SUSER_SNAME( dp.sid ) end
not in ('sys', 'INFORMATION_SCHEMA', 'guest')
order by 1

select u.name, *
from sys.sysusers u left join sys.syslogins l on UPPER(u.sid) = UPPER(l.sid)
where u.uid > 4 and u.issqlrole = 0 
and l.name is null
order by u.name
