--a.在srv1..author中创建触发器,实现数据即时同步
--新增同步
create trigger tr_insert_author on author
for insert
as
set xact_abort on
insert srv2.库名.dbo.author(id,name,telphone)
select id,name,telphone from inserted
go
--修改同步
create trigger tr_update_author on author
for update
as
set xact_abort on
update b set name=i.name,telphone=i.telphone
from srv2.库名.dbo.author b,inserted i
where b.id=i.id
go
--删除同步
create trigger tr_delete_author on author
for delete
as
set xact_abort on
delete b
from srv2.库名.dbo.author b,deleted d
where b.id=d.id
go
--3.实现同步处理的方法2,定时同步
--在srv1中创建如下的同步处理存储过程
create proc p_process
as
--更新修改过的数据
update b set name=i.name,telphone=i.telphone
from srv2.库名.dbo.author b,author i
where b.id=i.id and
(b.name<>i.name or b.telphone<>i.telphone)
--插入新增的数据
insert srv2.库名.dbo.author(id,name,telphone)
select id,name,telphone from author i
where not exists(
select * from srv2.库名.dbo.author where id=i.id)
--删除已经删除的数据(如果需要的话)
delete b
from srv2.库名.dbo.author b
where not exists(
select * from author where id=b.id)
go
--在srv1中创建如下的同步处理存储过程
create proc p_process
as
--更新修改过的数据
update b set name=i.name,telphone=i.telphone
from srv2.库名.dbo.author b,author i
where b.id=i.id and
(b.name<>i.name or b.telphone<>i.telphone)
--插入新增的数据
insert srv2.库名.dbo.author(id,name,telphone)
select id,name,telphone from author i
where not exists(
select * from srv2.库名.dbo.author where id=i.id)
--删除已经删除的数据(如果需要的话)
delete b
from srv2.库名.dbo.author b
where not exists(
select * from author where id=b.id)
go
--在srv1中创建如下的同步处理存储过程
create proc p_process
as
--更新修改过的数据
update b set name=i.name,telphone=i.telphone
