说明：  一个十分简单但是很清楚明了的利用C APII和MySQL交互的程序，实现基本的数据读写，查询等功能，主要意在示范连接的方法。注意，必须确保你已有安装mysql并相应C API包，并且编译时VC++的连接设置及工程设置应正确，相见源码内说明。
(A very simple but very clear understanding of the use of C APII and MySQL interactive process, to achieve basic reading and writing data, query and other functions, primarily intended to demonstrate connections. Attention to the need to ensure that you have to install mysql and the corresponding C API package, and compile VC++ connection settings and project settings should be correct, each other source within the description.)
