--应该没问题,试试用事务,下面是例子--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A,B库上创建测试表 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,仅A库的表建立,B库不用创建 create trigger t_test on test for insert,update,delete as--进行事务处理,如果表用标识列做主键,用下面的方法 BEGIN TRANSACTION delete from B.dbo.test where id in(select id from deleted) insert into B.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 B.dbo.test b on a.id=b.id
