PDW 的链接服务器错误

Question

我正在尝试从 SMP 服务器连接到 PDW 实例。链接服务器已建立，我可以从 SMP 查看 PDW 数据库。但是，当我尝试从 PDW 获取 select 数据时，出现以下错误：

OLE DB provider "SQLNCLI11" for linked server "x.x.x.x,x" returned message "Unspecified error".
Msg 104386, Level 16, State 1, Line 1
Stored procedure sp_tables_info_90_rowset_64 does not exist or is not supported.

会不会跟我的ID权限有关。我使用 windows 身份验证

连接到 SMP 服务器

Answer 1

PDW documentation 声明：

SQL statements must be submitted using the linked server EXECUTE statement. Using the EXECUTE statement avoids using four-part names for objects, which is not supported by SQL Server PDW. For example:

Use this: EXEC ('SELECT * FROM AdventureWorksPDW2012.dbo.dimCustomer') AT PDWLINK;

Don’t use this: SELECT * FROM PDWLINK.AdventureWorksPDW2012.dbo.dimCustomer

所以我不希望能够浏览链接服务器并获得数据库列表。不过，您可以运行查询。

供其他人参考，PDW/APS 文档解释了如何创建连接到 PDW 的 SQL 服务器链接服务器：
