Could not find server ‘DATABASE_NAME′ in sys.servers error - sql-server

Question

The code below is embedded in a .sql file in a vb.net project. It gives me an error:
Could not find server ‘DATABASE_NAME′ in sys.servers. Verify that the correct server name was specified. If necessary, execute the stored procedure sp_addlinkedserver to add the server to sys.servers.
I checked in sys.server and the LinkedDatabaseName is returned if i do a select * from sys.servers
Here is the code where I get the error....

Answer 1

The problem is that there are inconsistent usages of the $$DATABASE_NAME$$ substitution string. In most cases it is used to reference a specific database
$$DATABASE_NAME$$..txmr_TABLE1
but in the exec string:
EXEC $$DATABASE_NAME$$..dbo.txmr_ExtractPOCIS
there is one too many periods, which means that it is now referencing a different server and not a database.
Changing this statement to:
EXEC $$DATABASE_NAME$$.dbo.txmr_ExtractPOCIS
should resolve the problem.
