直接从链接服务器访问链接服务器

Question

I have two SQL Server instances:

• SQLSERVER64
• SQLSERVER32

In SQLSERVER32 , I have a linked server to a Paradox database called ParadoxDBLinkedServer .

To access some of the Paradox tables in the server I just execute the following statement:

SELECT * 
FROM [ParadoxDBLinkedServer]...Clients

Then, I need to access to these objects from the SQLSERVER64 instance. In order to do so, I created a linked server called [ .\\SQLSERVER32 ] in this instance pointing to SQLSERVER32 .

What I'm trying to do now is to access directly the ParadoxDBLinkedServer objects from the SQLSERVER64 instance. I mean, accessing a linked server from another linked server.

The query I´m trying to run is the following one:

SELECT * 
FROM [.\SQLSERVER32].[ParadoxDBLinkedServer ]...Clients

But I get this error:

The number name '.\\SQLSERVER32.ParadoxDBLinkedServer ...Clients' contains more than the maximum number of prefixes. The maximum is 3.

Is there any way to perform an access like this? What am I missing here?

I'm trying to avoid creating a View for each table of the ParadoxDBLinkedServer in the SQLSERVER32 instance to reduce overhead.

Answer 1

This is late, but hopefully can be helpful to someone else who comes to this post later. If you can use openquery then something like this should work:

SELECT * FROM OPENQUERY([.\SQLSERVER32], 'SELECT * FROM   OPENQUERY([ParadoxDBLinkedServer ],''SELECT * FROM Clients'')' )

Answer 2

select * from openquery (Linkedservername,'select * from tablename')
