C# "；update语句中的语法错误；尝试使用datagridview（也使用OleDbCommandBuilder）更新access数据库时

我正在datagridview中显示一个数据，并尝试从datagridview更新数据库。因此，我使用OleDbCommandBuilder生成更新命令。当点击更新按钮时，我得到“更新语句中的语法错误”

这是我的密码：

 private void listBox9_SelectedValueChanged(object sender, EventArgs e)
 {
        AppDomain.CurrentDomain.SetData("DataDirectory", Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData));
        connection = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0; Data Source=|DataDirectory|\\Trip Sheet Management System\\WABCO.mdb");
        sql = "SELECT ID,[TRIP COST] FROM TMSDETAILS";
        dataAdapter = new OleDbDataAdapter(sql, connection);
        dataTable = new DataTable();
        bindingSource = new BindingSource();
        connection.Open();
        dataAdapter.Fill(dataTable);
        bindingSource.DataSource = dataTable;
        dataGridView1.DataSource = bindingSource;
        connection.Close();
  }


 private void button8_Click(object sender, EventArgs e)
    {

        commandBuilder = new OleDbCommandBuilder(dataAdapter);

        try
        {
            dataAdapter.Update(dataTable);
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message);
        }
    }

当我点击更新按钮时，我在消息框中得到一个错误，上面写着“更新语句中的语法错误”

字段1：ID-自动编号，主键

---

字段2：旅行费用-人数

伙计们，我自己找到了答案

发生错误的原因是字段名包含一个空格，即TRIP COST

只需在command builder语句旁边添加两行

commandBuilder.QuotePrefix=“[”

commandBuilder.QuoteSuffix=“]”

这是经过编辑的代码

 private void listBox9_SelectedValueChanged(object sender, EventArgs e)
{
    AppDomain.CurrentDomain.SetData("DataDirectory", Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData));
    connection = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0; Data Source=|DataDirectory|\\Trip Sheet Management System\\WABCO.mdb");
    sql = "SELECT ID,[TRIP COST] FROM TMSDETAILS";
    dataAdapter = new OleDbDataAdapter(sql, connection);
    dataTable = new DataTable();
    bindingSource = new BindingSource();
    connection.Open();
    dataAdapter.Fill(dataTable);
    bindingSource.DataSource = dataTable;
    dataGridView1.DataSource = bindingSource;
    connection.Close();
}


private void button8_Click(object sender, EventArgs e)
{

    commandBuilder = new OleDbCommandBuilder(dataAdapter);
    commandBuilder.QuotePrefix = "["; 
    commandBuilder.QuoteSuffix = "]";

    try
    {
        dataAdapter.Update(dataTable);
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
}

希望它能帮助别人

调试代码时，确切的命令是什么？我在你的代码上没有看到任何更新语句。没有更新语句。这就是为什么我使用CommandBuilderMaybe，因为您已经关闭了dataAdapter的连接？没有。我没有关闭dataAdapter的连接。几乎几年后，我才真正帮助修复了某些问题+1.
