--即时同步两个表的实例:
--测试环境:SQL2000,远程主机名:xz,用户名:sa,密码:无,数据库名:test
--创建测试表,不能用标识列做主键,因为不能进行正常更新 --在本机上创建测试表,远程主机上也要做同样的建表操作,只是不写触发器 if exists (select * from dbo.sysobjects where id = object_id(N'[test]') and OBJECTPROPERTY(id, N'IsUserTable') = 1) drop table [test]
create table test(id int not null constraint PK_test primary key ,name varchar(10)) go
--创建同步的触发器 create trigger t_test on test for insert,update,delete as set XACT_ABORT on --启动远程服务器的MSDTC服务 exec master..xp_cmdshell 'isql /S"xz" /U"sa" /P"" /q"exec master..xp_cmdshell 'net start msdtc',no_output"',no_output
--启动本机的MSDTC服务 exec master..xp_cmdshell 'net start msdtc',no_output
--进行分布事务处理,如果表用标识列做主键,用下面的方法 BEGIN DISTRIBUTED TRANSACTION delete from openrowset('sqloledb','xz';'sa';',test.dbo.test) where id in(select id from deleted) insert into openrowset('sqloledb','xz';'sa';',test.dbo.test) select * from inserted commit tran go
--插入数据测试 insert into test select 1,'aa' union all select 2,'bb' union all select 3,'c' union all select 4,'dd' union all select 5,'ab' union all select 6,'bc' union all select 7,'ddd'
--删除数据测试 delete from test where id in(1,4,6)
--更新数据测试 update test set name=name+'_123' where id in(3,5)
--显示测试的结果 select * from test a full join openrowset('sqloledb','xz';'sa';',test.dbo.test) b on a.id=b.id
