I was going through comments on various posts to see if I have missed to answer any comments. I realized that there are quite a few times I have answered question which discuss about how to call stored procedure or query on linked server or another server. This is very detailed topic, I will keep it very simple.
I am making assumptions that remote server is already set up as linked server with proper permissions in application and network is arranged.
Method 1 : Remote Stored Procedure can be called as four part name:
EXEC [RemoteServer] .DatabaseName.DatabaseOwner.StoredProcedureName
EXEC [DEVSQL] .AdventureWorks.dbo.uspGetEmployeeManagers ’42′
Method 2 : Use Distributed Query functions (OpenQuery())
Let me know if you want me write about above two methods in detail.
