mysqldb编程错误

Question

我在尝试使用 MySQLdb 插入 table 时遇到错误，但无法弄清楚。我查看了如何捕获错误，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，我没有得到任何额外的信息，当我尝试 print e 时，我得到了一个错误。我需要一些帮助来获取错误以提供更多详细信息。我将包括整个代码，以防有人非常棒，可以首先看到我哪里出错了。然后我什至不关心错误陷阱。好的，是的，我这样做是因为我相信我很快就会再次需要它。哈哈。我实际上有 8 列需要更新。我正在尝试使用消除过程并且一次只尝试几个。 UPC、Name 和其他一些插入正常，但 Modl、Path 和 Desc 导致错误。如有任何帮助，我们将不胜感激。

我明白发生了什么事。这实际上是两件事。其中有几个我将列设置为 varchar(200) 并且获得了超过 2400 个字符，因此增加它修复了这个问题。在 URL 上，我没有转义它，这导致了错误。再次感谢。 – 尼克刚刚编辑
