运行截图:
mysql connector/c++ 文档(包括例子):
http://dev.mysql.com/doc/refman/5.1/en/connector-cpp.htmlmysql connector/c++ api下载:
http://dev.mysql.com/downloads/connector/cpp/下载以后lib和include文件夹直接copy到你vc的lib和include里
然后工程库引用里添加对mysqlcppconn.lib的引用
可能要将mysqlcppconn.dll放到c:\windows文件夹下
具体可以参考这里:

http://bugs.mysql.com/bug.php?id=44272所以代码要在release下编译运行,driver->connect才能连接成功
