使用SQL脚本访问操作远程数据库

 1 USE [Hik]
 2 GO
 3 /****** Object:  StoredProcedure [dbo].[sp_test]    Script Date: 08/21/2015 09:55:21 ******/
 4 SET ANSI_NULLS ON
 5 GO
 6 SET QUOTED_IDENTIFIER ON
 7 GO

28 --查询示例

30 --set @[email protected]+‘.Hik‘
31 --declare @sql Nvarchar(1000)=N‘select @num=COUNT(*) from ‘[email protected]+‘.dbo.Device‘;
32 --Exec sp_executesql @sql,N‘@num int output‘,@num output
33 --select @num
34
35 declare @sql Nvarchar(max)=N‘select count(*) from ‘+@ServerName+‘.Hik.dbo.Device‘;
36 Exec sp_executesql @sql;
37
38 --处理完成后删除链接服务器
39 exec sp_dropserver  @ServerName, ‘droplogins ‘;

41 END

我也是在网上找到的资源，然后修改了一下，实现了需求的原形，供大家参考。
