INSERT INTO 语句中的语法错误.System.Data.OleDb.OleDbErrorCollection

Syntax error in INSERT INTO statement. System.Data.OleDb.OleDbErrorCollection

我的代码如下.请帮我解决这个问题.

My code is given below. Please help me to resolve this issue.

protected void Button1_Click(object sender, EventArgs e)
{
    string conString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:UsersadminDesktopdelSHAFIdb.accdb";
    OleDbConnection con = new OleDbConnection(conString);
    OleDbCommand cmd = con.CreateCommand();
    string text = "INSERT INTO TEST (Number, Amount) VALUES (?, ?)";
    cmd.CommandText = text;
    try
    {
        con.Open();
        cmd.Parameters.AddWithValue("@Number", txtAmount.Text);
        cmd.Parameters.AddWithValue("@Amount", txtOrder.Text);
        cmd.ExecuteNonQuery();
    }
    catch (OleDbException ex)
    {
        txtAmount.Text = "Sorry";
        Response.Write(ex.Message.ToString() + "<br />" + ex.Errors.GetType());
    }
}

推荐答案

你的代码是正确的，除了缺少 using 语句 围绕一次性对象，但真正的问题是单词 NUMBER.它是 MSAccess 的保留关键字.
用方括号括起来.

Your code is correct, apart from the lacking of using statement around disposable objects, but the real problem is the word NUMBER. It is a reserved keyword for MSAccess.
Use it enclosed in square brackets.

string text = "INSERT INTO TEST ([Number], Amount) VALUES (?, ?)";

但是，如果仍有可能，我真的建议您更改该列名称.这个问题会变得很烦人.

However, if it is still possible, I really suggest you to change that column name. This problem will become very annoying.

protected void Button1_Click(object sender, EventArgs e)
{
    string conString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:UsersadminDesktopdelSHAFIdb.accdb";
    using(OleDbConnection con = new OleDbConnection(conString))
    using(OleDbCommand cmd = con.CreateCommand())
    {
        string text = "INSERT INTO TEST ([Number], Amount) VALUES (?, ?)";
        cmd.CommandText = text;
        try
        {
            con.Open();
            cmd.Parameters.AddWithValue("@Number", txtAmount.Text);
            cmd.Parameters.AddWithValue("@Amount", txtOrder.Text);
            cmd.ExecuteNonQuery();
        }
        catch (OleDbException ex)
        {
            txtAmount.Text = "Sorry";
            Response.Write(ex.Message.ToString() + "<br />" + ex.Errors.GetType());
        }
    }
