sp_addlinkedserver '(null)' is an invalid product name

使用SSMS 2008客户端工具逆向生成了创建链接服务器的脚本时,在测试环境执行是报如下错误:'(null)' is an invalid product name.

USE [master]
GO
IF EXISTS (SELECT srv.NAME 
           FROM   sys.servers srv 
           WHERE  srv.server_id != 0 
                  AND srv.NAME = N'MES_DB_LINK_TEST') 
  EXEC master.dbo.Sp_dropserver 
    @server=N'MES_DB_LINK_TEST', 
    @droplogins='droplogins' 
 
go 
 
EXEC master.dbo.Sp_addlinkedserver 
  @server = N'MES_DB_LINK_TEST', 
  @provider=N'SQLNCLI', 
  @datasrc=N'192.168.xxx.xxx', 
  @catalog=N'TEST' 
 
EXEC master.dbo.Sp_addlinkedsrvlogin 
  @rmtsrvname=N'MES_DB_LINK_TEST', 
  @useself=N'False', 
  @locallogin=NULL, 
  @rmtuser=N'tuser', 
  @rmtpassword='123456'

'(null)' is an invalid product name.

出现如上错误,是因为这个是SQL Server Management Studio 的一个bug来的。它逆向生成脚本时,生成的脚本少了一些参数,所以你执行脚本时就会报上述错误。这个bug已经在SQL Server Management Studio 2012解决了,你用SSMS 2012逆向生成脚本就会发现会多一个参数@srvproduct

USE [master] 
 
go 
 
IF EXISTS (SELECT srv.NAME 
           FROM   sys.servers srv 
           WHERE  srv.server_id != 0 
                  AND srv.NAME = N'MES_DB_LINK_TEST') 
  EXEC master.dbo.Sp_dropserver 
    @server=N'MES_DB_LINK_TEST', 
    @droplogins='droplogins' 
 
go 
 
EXEC master.dbo.Sp_addlinkedserver 
  @server = N'MES_DB_LINK_TEST', 
  @srvproduct=N'', 
  @provider=N'SQLNCLI', 
  @datasrc=N'192.168.xxx.xxx', 
  @catalog=N'TEST' 
 
EXEC master.dbo.Sp_addlinkedsrvlogin 
  @rmtsrvname=N'MES_DB_LINK_TEST', 
  @useself=N'False', 
  @locallogin=NULL, 
  @rmtuser=N'tuser', 
  @rmtpassword='123456'
