一.摘要 本文通过实际业务场景讲解如何实现跨数据库服务器的数据查询, 以及跨表更新的SQL语法. 二.业务场景 想实现的功能很简单, 在我的本地一个表用来保存省的信息: T_Province 在另外一台服务器上也有一个保存省的表province,其中有我本地没有的provience_name_en和provience_id信息.我希望将它们保存到我的表中. 虽然用程序很容易实现,但是我觉得如果能直接操作数据库的话将更简单,而且还能学习到跨服务器查询的知识. 三.准备工作 首先我在本地 T_Province 表中添加了 ProvinceNameEn 和 ProvinceId 两个字段.接下来就要想办法为这两个字段填充数据. 四.跨服务器查询 首先需要解决跨服务器查询的问题. 先来看我的最终实现: --创建链接服务器 exec sp_addlinkedserver @server= 'SQL2', @srvproduct= '', @provider='SQLNCLI', @datasrc = '192.168.9.123' --登录链接服务器 exec sp_addlinkedsrvlogin @rmtsrvname = 'SQL2', @useself = 'false ', @locallogin = null, @rmtuser ='sa', @rmtpassword =
