1.安装安装mysqlconnector
2.配置mysqlconnector
ODBC数据管理器->系统DSN->添加->mysql ODBC 5.3 ANSI driver->填入data source name如jt,mysql的ip、用户名、密码即可
3.新建链接服务器
exec sp_addlinkedserver
@server=’jt’, –ODBC里面data source name
@srvproduct=’mysql’, –自己随便
@provider=’MSDASQL’, –固定这个
@datasrc=NULL,
@location=NULL,
@provstr=’DRIVER={MySQL ODBC 5.3 ANSI Driver};SERVER=192.168.5.188;DATABASE=suzhou;UID=root;PORT=3306;’,
@catalog = NULL
exec sp_addlinkedsrvlogin
@rmtsrvname=’jt’,
@useself=’false’,
@rmtuser=’root’,
@rmtpassword=’password’;
select * from openquery(jt,’SELECT * FROM sz ; ‘)
GO
USE [master]
GO
EXEC master.dbo.sp_serveroption @server=N’jt’, @optname=N’rpc out’, @optvalue=N’TRUE’
GO
EXEC master.dbo.sp_serveroption @server=N’jt’, @optname=N’remote proc transaction promotion’, @optvalue=N’false’
GO
—4.sqlserver和mysql新建库和表
create database suzhou;
create table sz(
id int not null identity(1,1) primary key,
orderno char(20) not null,
ordertime datetime not null default getdate(),
remark varchar(200)
)
go
create table sz(
id int(11) not null ,
orderno char(20) not null,
ordertime datetime(6) not null ,
remark varchar(200),
primary key (id)
) engine=innodb default charset=utf8;
—5.建立回环
–建立LOOPBACK 服务器链接
EXEC sp_addlinkedserver @server = N’loopback’ , @srvproduct = N’ ‘ , @provider = N’SQLNCLI’,
@datasrc = @@SERVERNAME
go
–设置服务器链接选项，阻止SQL Server 由于远过程调用而将本地事务提升为分布事务（重点）
USE [master]
GO
EXEC master.dbo.sp_serveroption @server=N’loopback’, @optname=N’rpc out’, @optvalue=N’TRUE’
GO
EXEC master.dbo.sp_serveroption @server=N’loopback’, @optname=N’remote proc transaction promotion’, @optvalue=N’false’
GO
—-6.编写触发器和存储过程
—-6.1 insert
–重写触发器
use suzhou
go
alter trigger tr_insert_sz on suzhou.dbo.sz
for insert
as

select @id=id,@orderno=orderno,@ordertime=ordertime,@remark =remark from inserted;
begin
print @id
print @orderno
print @ordertime
print @remark
exec loopback.suzhou.dbo.sp_insert @id,@orderno,@ordertime,@remark
end
go
