通过SQLServer 2008 操作 MySQL的方法

mysql sqlserver operate

在公司中经常会遇到部署多种数据库环境的情况,对于开发人员来说经常在不同数据库之间转换确实有些繁琐,本篇将介绍从SQLServer 操作MySQL 数据库的方法。

数据库测试环境
1. SQL Server 2008

2. MySQL 5.1.36
Database: Test
Table: TestTable

创建MySQL 测试表
代码如下:
CREATE TABLE `testtable` (
`id` int(11) DEFAULT NULL,
`name` varchar(50) DEFAULT NULL,
`age` int(11) DEFAULT NULL
)


创建Link Server
下面来创建一个与MySQL交互的链接(类似Oracle 的DBLink),在SQL Server 管理器中右键Server Objects 目录下的Linked Servers 点击“New Linked Server”:

Linked server 链接名称
Server Type 选择“Other data source”
Provider 选择“Microsoft OLE DB Provider for ODBC Drivers”
Product name 填写MySQL 主机地址
Provider String 填写 Driver={MySQL ODBC 5.1 Driver};Server=ServerName;Database=myDB;
User=myUserName;Password=myPassword;Option=3;

也可以通过TSQL 直接创建:
代码如下:
EXEC master.dbo.sp_addlinkedserver
@server = N'MYSQLLINK',
@srvproduct = N'localhost',
@provider = N'MSDASQL',
@provstr = N'Driver={MySQL ODBC 5.1 Driver};Server=localhost;
Database=test;User=root;Password=root;Option=3;'

EXEC master.dbo.sp_addlinkedsrvlogin
@rmtsrvname = N'MYSQLLINK',
@useself = N'False',
@locallogin = N'localhost',
@rmtuser = N'root',
@rmtpassword = N'root'

创建完成后便会看到下图中的链接:


操作MySQL 数据库
在SQL Server 中通过OPENQUERY 函数对MySQL 进行操作,该函数包含两个参数:第一个为已创建的链接名称,第二个为SQL 查询,它将返回对Linked Server 的读取或修改操作。如下操作示例:

OPENQUERY ([LinkedServer], 'SELECT * FROM [RemoteTable]')向TestTable 中插入测试数据:

insert into openquery(mysqllink,'select * from testtable')
select 1,'Peter',30;查询数据:

select * from openquery(mysqllink,'select * from testtable');

修改数据:
代码如下:
update openquery(mysqllink,'select * from testtable')
set name='Jone' where id=1;


删除数据:
代码如下:
delete from openquery(mysqllink,'select * from testtable')
where id=1;
