如何在 SQL Server 2008 R2 中对从两个数据库连接的表使用 PIVOT

Question

我在加入两个数据库后获取数据，第一个是“listserver”，第二个是“newsletter”。

这是我的原始查询，它为一位订阅者返回 4 条记录。

select 
    gmin. MEMBER_PROPERTY,gmin .MEMBER_VALUE , m.*  
from 
    SUBSCRIBER s
inner join 
    listserv.dbo .MEMBER m on m.MEMBER_EMAIL= s.SUBSCRIBER_EMAIL
inner join 
    listserv.dbo .MEMBER_ATTRIBUTES gmin on gmin.MEMBER_ID= m.MEMBER_ID
where 
    s .SUBSCRIBER_GROUP  like '%abc%' 
order by 
    m.MEMBER_DATE_ADDED desc

此查询为单个订阅者返回 4 行，因为我在“MEMBER_ATTRIBUTES”表中有 4 个条目。

这是结构

现在我想为每个订阅者在一行中获取这些数据。我知道我可以使用 PIVOT 来做到这一点，但我不知道如何在上述查询中使用 PIVOT。

请帮助我如何实现我的目标，在此先感谢。

更新我想要以下格式的结果：

我已使用以下查询来实现我的目标。 Use PIVOT for Multiple records in SQL SERVER 和 Getting Null data while using PIVOT in sql server 2008 R2 questions 帮助我构建了这个查询。
