在sys.servers错误中找不到服务器'DATABASE_NAME'

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.
