Question

我在C＃中创建一个简单的程序，您可以在其中添加和操作MS Access数据库中的数据。在我的代码中，我添加了一个按钮来更新现有数据，或者创建一个新字段，但我一直收到错误，说我的insert语句有问题。

这是我的代码：

private void btnUpdate_Click(object sender, EventArgs e)
{
    try
    {
        String Code = textBox1.Text;
        String Name = textBox2.Text;
        String Address1 = textBox3.Text;
        String Address2 = textBox4.Text;
        String Address3 = textBox5.Text;
        String balance = textBox6.Text;
        String Sales = textBox7.Text;
        String Cost = textBox8.Text;

        if (Choice == 1)
        {
            sql = String.Format("UPDATE Debtors " + "SET names = '{0}'," + "address1 = {1}," + "Address2 = {2}," + "Address3 = {3}," + "Balance = '{4}' " + "Sales = '{5}' " + "Cost = '{6}' " + "WHERE accountCode = {7};", Name, Address1, Address2, Address3, balance,Sales,Cost, Code);
        }
        else
        {
            sql = String.Format("INSERT INTO Debtors(names, address1, address2, address3, Balance, salesYearToDate, costYearToDate) " + "VALUES " + "('{0}'," + "'{1}'," + "'{2}'," + "'{3}'," + "{4}," + "{5}," + "{6});", Name, Address1, Address2, Address3, balance, Sales, Cost);
        }

        Ey(sql);
        DataLoad();
        BackTrack();
    }
    catch (System.Exception exc)
    {
        MessageBox.Show(exc.Message);
    }
}

更新声明中的余额和销售后缺少一些逗号。

也不需要分号。

您还需要提交您的陈述。

此致
