mysqldb编程错误

我在尝试使用MySQLdb插入表时遇到错误,无法弄明白。我查找了如何捕获错误,但是当我添加代码来捕获它时,当我尝试使用raise e而不是print e时,我没有得到任何其他信息,当我尝试打印时,我得到一个错误。我需要一些帮助来获取错误以给我更多细节。我会包含整个代码,万一有人非常棒,看看我哪里出错了。然后我甚至不关心错误捕获。好的,我是的,因为我相信我很快就会再次需要它。大声笑。我实际上有8列需要更新。我正在尝试使用消除过程,一次只尝试一对。像UPC,Name和其他几个插入很好,但Modl,Path和Desc导致错误。任何帮助都将受到赞赏和感谢。

我弄清楚发生了什么。这实际上是一些事情。其中一个我将列设置为varchar(200)并且已经超过2400个字符,因此增加它固定了它。在我的URL上没有逃避它,这导致了错误。再次感谢。 - 尼克刚刚编辑
