Windows下C++连接MySQL

步骤：
1. 安装MySQL数据库
2. 项目属性页->C/C++->常规->附加包含目录：xxxMySQL Server 5.6include
3. 项目属性页->链接器->常规->附加库目录：xxxMySQL Server 5.6lib
4. 项目属性页->链接器->输入->附加依赖项：libmysql.lib 将libmysql.dll拷贝到项目中
5. 引入头文件:#include<Windows.h> #include <mysql.h>
测试代码：

#include<iostream>
#include<Windows.h>
#include <mysql.h>
#include<string>


using namespace std;
