Question

我认为错误可能来自我可能正在使用的保留字，但我不知道哪个字。上次我遇到这个问题是在INSERT INTO语句中，我通过在保留字周围加上括号来修复它。但如果这是一个保留字的问题。当代码是这样时，如何在保留字周围加上括号？有什么帮助吗？

        OleDbCommandBuilder cb;
        cb = new OleDbCommandBuilder(clientAD);

        DataRow dRow = clientDS.Tables["Client"].Rows[cInc];

        clientAD.Update(clientDS, "Client");

我将默认值放入行中，并检查以确保数据类型匹配。我最初没有包含字段名称，而是第一次使用字段索引。

Answer 1

dRow [“C o_Citizenship”]在C和o之间是否有空格？

Answer 2

我会将它包装在try / catch中，看看它特别窒息

try
{
   clientAD.Update(clientDS, "Client");
}
catch( Exception oError )
{
   MessageBox.Show( oError.Message );
}

但是如果你在实际的MessageBox上放置一个断点并在watch调试窗口（或局部变量调试窗口）中查看整个oError对象，它可能会为你公开一些更具体的细节。就我们所知，您可能会尝试在具有自动增量列的表上发出“更新”，该列是专门为只读的，不会让您触摸它。如果您尝试设置ID，可能会考虑更改的值并尝试强制通过。

另外，您引用的是“clientAD”，它是OleDbDataAdapter的一个实例。您可能必须指定作为基础的主键“列”。
