Use synonyms, views on srv 2 ? Srv3 queries srv2 (which queries srv1)
-
Hello Jo
srv2 is an intermediary to send data a srv1 (main server)
srv3 is a Tester with database, and I want to send since srv3 to srv1
Insert into svr1.DB.dbo.table
Select fields from srv3.DB.dbo.table WHERE sent='N'
But I dont see srv1 since srv3
-
Hello Jo
I make this:
Link svr1 to svr2, then link srv3 to svr2.
In srv2 a stored procedure was made to send to svr1.
in srv3 a stored procedure was made to get values and execute the stored procedure in srv2 passing values
I still don't try, but tomorrow I will.

My question would be.... why do you NEED to go through the intermediate server to begin with?

Hello Jeff
For security policies. which this as srv3 is a computer with windows xp and sql server express and cannot be connected to the main network.

What sort of security policy allows you to have a 'server' running Windows XP?

Can you use SSIS? If not Jo Pattyn's option is the better one. If you're comfortable with SSIS here’s how I/we used to do something similar as part of an ETL solution until we moved systems.
From srv2 create a linked server to Srv3
In an SSIS project / solution have two connections Source “master” database on srv2, and destination <yourdatabase> on Srv1
Create a package, as a “Data Flow Task” with an OLE DB Source with a Data access mode of “SQL command” which runs your query from the data on Srv3 in the following format;
SELECT column1, column2…columnX
FROM <linkedServernameofSrv3on Srv2>.<DatabaseSRv3>.<Schema>.<table or view>
Note 1 – the <linkedServernameofSrv3on Srv2> is the name you created earlier in an earlier step.
Note 2– if the source is complex a View might be a better option than a complex query in
Add an OLEDB destination connected to srv1 to the destination table. Run the package or deploy it to SSISDB.
My/our solution did a couple of other things such as truncate the target table before copying data across. We then processed the data further downstream as part of our ETL.

Phil,
The srv3 is a tester machine (plc and other devices) for this reason exists other local network.

Rob,
I am going to try.......

You used the terms security and XP in the same sentence, and that's what triggered my response.
Support for XP ended in 2014. It cannot be considered secure.
