C executeQuery()错误显示表中的MySQL数据

SQL error. Error message:

字面上一片空白.如果我在executeQuery()中使用SELECT语句而不是INCLUDE语句,它运行时没有问题,也没有错误消息,只显示我的表(或部分表).我错过了什么？

我正在使用Visual Studios 2015和MySQL Server.

最终目标是使用C将API与SQL表连接,以根据特定的时间跨度记录数据.这是最初的步骤之一,只是为了确保我可以正确地将MySQL与C链接起来.

很抱歉,如果这篇文章写得不好,第一次在这里,绝对不是一个有经验的程序员…另外,我调查了其他线程,但由于这是如此具体,我发现它们没有帮助.
