SQL Server实现跨库查询（跨库select insert）

方法一：

select * from servername.dbo.tablename

方法二：

select * from OPENDATASOURCE(
         \'SQLOLEDB\',
         \'Data Source=远程ip;User ID=sa;Password=密码\'
         ).库名.dbo.表名
where 条件

select top 100 * from OPENDATASOURCE(
         \'SQLOLEDB\',
         \'Data Source=192.168.6.100;User ID=sa;Password=1234\'
         ).[zhaolx-test].dbo.TGongwen

where gid <5

insert into OPENDATASOURCE(
         \'SQLOLEDB\',
         \'Data Source=192.168.6.100;User ID=sa;Password=1234\'
         ).[zhaolx-test].dbo.t_aaa (id ,name )values(\'001\',\'Tom\')

select top 100 * from OPENDATASOURCE(
         \'SQLOLEDB\',
         \'Data Source=192.168.6.100;User ID=sa;Password=1234\'
         ).[zhaolx-test].dbo.t_aaa
