MSSQL 跨服务器进行不同数据库的操作

把一个表的数据插入到另一服务器的相同表结构的一张表中：

        insert into opendatasource('SQLOLEDB','Data Source=*.*.*.*;user ID=sa;password=*****;')
    .dbname.dbo.tablename select top 10 * from dbname.dbo.tablename

如果执行时出现如下提示：

SQL Server blocked access to STATEMENT 'OpenRowset/OpenDatasource' of component 'Ad Hoc Distributed Queries' because this component is turned off as part of the security configuration for this server. A system administrator can enable the use of 'Ad Hoc Distributed Queries' by using sp_configure. For more information about enabling 'Ad Hoc Distributed Queries', see "Surface Area Configuration" in SQL Server Books Online.

 

此操作因为服务器安全策略被禁止，可以更改设置。

 

exec sp_configure 'show advanced options',1
reconfigure
exec sp_configure 'Ad Hoc Distributed Queries',1
reconfigure
go

select * from Product p inner join
opendatasource('SQLOLEDB','Data Source=Macaco-Online;user ID=sa;password=sa密码;').Company.dbo.Product p2
on P.PID=p2.PID
go

exec sp_configure 'Ad Hoc Distributed Queries',0
reconfigure
exec sp_configure 'show advanced options',0
reconfigure
go
