Question

我正在尝试使用插入查询（访问是数据库程序）但是我收到如下错误：

System.Data.OledDb.OleDbException (0x800004005): Operation must use an updateable query.

这是在我创建了一个.msi文件并安装它之后（它在Visual Studio中调试/运行时工作正常）。删除查询也不起作用，也不更新（只是选择查询）。当我尝试删除时，收到错误消息“无法从指定的表中删除”）。（这是完整的异常消息：http://imgur.com/BSuh0nS）

以下是处理此

的两种方法的代码

public void InsertData()
{
        dbc.Open();

        using (dbCmd = new OleDbCommand("INSERT INTO members (household_head, birthday, phone, email, address, status, spouse, spouse_birthday, spouse_phone, spouse_email, " +
          "anniversary, spouse_status, child1, child1_birthday, child1_email, " +
     "child2, child2_birthday, child2_email, child3, child3_birthday, child3_email, child4, child4_birthday, child4_email, child5, child5_birthday, child5_email," +
     "child6, child6_birthday, child6_email, child7, child7_birthday, child7_email) " +
     "VALUES (@txtBox_householdHead, @txtBox_householdHeadBirthday, @txtBox_householdHeadPhone, @txtBox_householdHeadEmail, @txtBox_householdHeadAddress, @txtBox_householdHeadStatus, " +
     "@txtBox_spouse, @txtBox_spouseBirthday, @txtBox_spousePhone, @txtBox_spouseEmail, @txtBox_Anniversary, @txtBox_spouseStatus, " +
     "@txtBox_child1, @txtBox_child1Birthday, @txtBox_child1Email, " +
     "@txtBox_child2, @txtBox_child2Birthday, @txtBox_child2Email, @txtBox_child3, @txtBox_child3Birthday, @txtBox_child3Email, @txtBox_child4, @txtBox_child4Birthday, @txtBox_child4Email, " +
     "@txtBox_child5, @txtBox_child5Birthday, @txtBox_child5Email, @txtBox_child6, @txtBox_child6Birthday, @txtBox_child6Email, @txtBox_child7, @txtBox_child7Birthday, @txtBox_child7Email)", dbc))
        {
            try
            {
                InsertDBParameters(ref dbCmd);

                dbCmd.ExecuteNonQuery();
            }
            catch (OleDbException ex)
            {
                MessageBox.Show(ex.ToString());
                return;
            }
        }


        MessageBox.Show("Record inserted.");

        ClearAll(this);

        dbc.Close();

}

和InsertDBParameters方法：

private void InsertDBParameters(ref OleDbCommand cmd)
{

        foreach (Control c in Controls)
        {
            if (c is TextBox)
            {
                listOfTextboxes.Add(new KeyValuePair<string, string>(((TextBox)c).Name, ((TextBox)c).Text));
            }
        }

        for (int i = 0; i < listOfTextboxes.Count; i++)
        {
            cmd.Parameters.AddWithValue(String.Format("@{0}", listOfTextboxes[i].Key.ToString()), listOfTextboxes[i].Value);
        }

}

任何帮助将不胜感激，

谢谢！

我想象它必须是我迄今为止所研究的许可事物，但我不确定。这是我的连接字符串，如果它也有帮助：

OleDbConnection db = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\qbcdb.mdb");

操作必须使用可更新的查询 - 选择查询工作正常。
