关于HKROnline SyncNavigator 注册机价格的问题

HKROnline SyncNavigator 8.4.1 非破解版注册机授权激活教程

—安装安装mysqlconnector
http://www.mysql.com/products/connector/
/*
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
*/
–新建链接服务器
exec sp_addlinkedserver
@server=’MySqll_Aggregation’,–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=172.17.29.33;DATABASE=bi;UID=zhaowenzhong;PORT=3306;’,
@catalog=NULL
—创建连接mysql数据库的账号及密码
exec sp_addlinkedsrvlogin
@rmtsrvname=’MySqll_Aggregation’,—-ODBC里面data source name
@useself=’false’,
@rmtuser=’zhaowenzhong’,—mysql账号
@rmtpassword=’mysqldba@2015′;–mysql账号其密码
—测试是否可以访问mysql数据库中的表
select * from openquery(MySqll_Aggregation,’SELECT * FROM tb; ‘)
—–建立允许远程访问连接操作
USE [master]
GO
EXE Cmaster.dbo.sp_serveroption@server=N’MySqll_Aggregation’,@optname=N’rpc out’,@optvalue=N’TRUE’
GO
EXEC master.dbo.sp_serveroption@server=N’MySqll_Aggregation’,@optname=N’remote proc transaction promotion’,@optvalue=N’false’
GO

–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
—编写触发器和存储过程
–insert
CREATE TRIGGER TR_INSERT_TB ON DB_TY2015.DBO.TB
FOR INSERT
AS
DECLARE@ID INT,
@QTY INT
SELECT@ID=ID,@QTY=QTY FROM INSERTED;
BEGIN
EXEC loopback.db_ty2015.dbo.sp_insert@id,@qty;
END
CREATE PROCEDURE SP_INSERT
@ID INT,
@QTY INT
AS
BEGIN
SET NOCOUNT ON
INSERT OPENQUERY(db_ty2015,’select * from tb’)(id,qty) values (@id,@qty);
SET NOCOUNT OFF
END

—update
CREATE TRIGGERT R_UPDATE_TB ON DB_TY2015.DBO.TB
FOR UPDATE
AS
DECLARE @ID INT,@QTY INT
SELECT@ID=ID,@QTY=QTY FROM INSERTED;
BEGIN
EXEC loopback.db_ty2015.dbo.sp_update@id,@qty;
END

CREATE PROCEDURE SP_UPDATE
@ID INT,
@QTY INT
AS
BEGIN
SET NOCOUNT ON
UPDATE OPENQUERY(db_ty2015,’select * from tb’) SET qty=@qty WHERE id=@id
SET NOCOUNT OFF
END

–delete
CREATE TRIGGER TR_DELETE_TB ON DB_TY2015.DBO.TB
FOR DELETE
AS

DECLARE @ID INT
SELECT@ID=ID FROM DELETED;
BEGIN
EXEC loopback.db_ty2015.dbo.sp_DELETE@id;
END

CREATE PROCEDURE SP_DELETE
@ID INT
AS
BEGIN
SET NOCOUNT ON
DELETE OPENQUERY(db_ty2015,’select * from tb’) WHERE id=@id
SET NOCOUNT OFF
END

——-初始化数据表已存在的情况
insert into penquery(MySqll_Aggregation,’select * from bi.tb’) select*from[FSLogin].[dbo].[tb]with(nolock)
—从mysql同步表结构及数据到sqlserver上
select * into [SqlServerDBName].dbo.MYTest from openquery(localmysql,’select * from mysqldbname.weibosession’)
