  1.--直接跨数据库连接

  OPENDATASOURCE('SQLOLEDB','Server=10.252.35.194\GZ,1435;Uid=mrms2;pwd=mrms1234')。mrmsv3_backup_im.[dbo].[s2] t

  其中变量为IP、 账号、密码、 数据库名、账户名、表名

  2.--建立远程访问连接

  比如我现在在本机,要方便的访问10.244.8.193(sa,1),其中sa/1分别为账号密码

  就需要在本机执行下列命令:

  exec sp_addlinkedserver   'bowinserver', '', 'SQLOLEDB', '10.244.8.193'

  exec sp_addlinkedsrvlogin 'bowinserver', 'false',null, 'sa', '1'

  其中变量为自定义名、IP、账号、密码

  命令中bowinserver即自定义名,接下来我要访问10.244.8.193(sa,1) 中mrmsv3_cf_dev数据库的cf_user表:

  SELECT * FROM bowinserver.mrmsv3_cf_dev.dbo.cf_user
