我无法使用C#添加数据访问2007，任何人都可以帮助我吗
本文关键字：2007 任何人 都可以 帮助 访问 数据 添加 | 更新日期: 2023-09-27 17:50:23
我试图使用C#将数据插入Access 2007，我从stackerflow获得了一些代码，将数据插入到一个表中确实很有帮助，但我试图将数据插入两个具有一对多关系的表中，代码将运行，它没有交战或错误，但当我点击插入按钮时，会有一些消息框，告诉我由于插入语句中的语法错误而失败。有人能修复这个问题吗？？？另外，我在form2上有一些按钮，比如更新、搜索，当我点击其中一个按钮时，窗口将打开。如果我点击按钮10次，上一个窗口将不会关闭。。。。Please是这门语言的新手，我需要一些代码方面的帮助。
这是我的密码。。。

在您的第一个插入语句中，Remark后面有一个"，"，我认为这可能会导致无效语法错误。
String my_querry = "INSERT INTO crtPro(Name,AR,Wereda,Kebele,House_No,P_O_Box,Tel,Fax,Email,Item,Dep,Status,Remark**,**
