我在 olecom.ExecuteNon Query() 方法上遇到错误。我也尝试将日期字段转换为字符串，但它仍然没有帮助。我也没有被告知导致此问题的字段。 有人可以帮我弄这个吗？ 谢谢。
【问题讨论】：
如果您格式化您的代码，并且只发布相关部分会很有帮助... 抱歉这么长的代码，我发布长代码的原因是我可能在代码中犯了错误（错字或字符串/int互换）。我认为如果我修剪这段代码，我可能会隐藏一个可能的问题区域。不过感谢您的评论。如果您仍然希望我修剪代码，请告诉我。谢谢，希德 @sidhanshu：至少去掉行间多余的空格，以便我们阅读。 我只是把SQL剥离出来，放到access 2007中，运行成功。您使用的是哪个版本的 Access？ @SteveCav：我正在运行 Access 2007。谢谢 【参考方案1】：offensestate 缺少“@”。在您的插入值中应该是 @offensestate。
【讨论】：
感谢您的建议，但不幸的是，它并没有消除错误。我会去掉代码中多余的空格。 我已尝试删除代码和文本中的所有空格。我希望这有帮助。谢谢您的帮助。 -Sid以上是关于条件表达式中的数据类型不匹配的主要内容，如果未能解决你的问题，请参考以下文章
