How to fix an Exception in DBHandlerSystem.Data.OleDb.OleDbException (0x800

[kinbo]

I wrote a C# code called parent. When i run the program and try to add parent details to the database( microsoft access 2010), it gives me this error:

Exception in DBHandlerSystem.Data.OleDb.OleDbException (0x80040E14): Syntax error in INSERT INTO statement. at System.Data.OleDb.OleDbCommand.ExecuteCommandTextErrorHandling(OleDbHResult hr) at System.Data.OleDb.OleDbCommand.ExecuteCommandTextForSingleResult(tagDBPARAMS dbParams, Object& executeResult) at System.Data.OleDb.OleDbCommand.ExecuteCommandText(Object& executeResult) at System.Data.OleDb.OleDbCommand.ExecuteCommand(CommandBehavior behavior, Object& executeResult) at System.Data.OleDb.OleDbCommand.ExecuteReaderInternal(CommandBehavior behavior, String method) at System.Data.OleDb.OleDbCommand.ExecuteNonQuery() at AdminOffice._Default.Button1_Click(Object sender, EventArgs e) 

here is what i wrote

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.OleDb;

namespace AdminOffice
{
    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }
        protected void Button1_Click(object sender, EventArgs e)
        {
            string connString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=J:\...\reg.accdb"; // put your path
            OleDbConnection myConnection = new OleDbConnection(connString);

            string myQuery = "INSERT INTO Parent( Name, Surname, Address, Postcode, Tel number, Email, UserName, Password) VALUES ( '" + TextBox1.Text + "' , '" + TextBox2.Text + "' , '" + TextBox3.Text + "' , '" + TextBox4.Text + "' , '" + TextBox5.Text + "' , '" + TextBox6.Text + "' , '" + TextBox7.Text + "' , '" + TextBox8.Text + "')";
            OleDbCommand myCommand = new OleDbCommand(myQuery, myConnection);

            try
            {
                myConnection.Open();
                myCommand.ExecuteNonQuery();
                Label1.Text = "successful registration";
            }
            catch (Exception ex)
            {
                Label1.Text = "Exception in DBHandler" + ex;
            }
            finally
            {
                myConnection.Close();
            }

        }
    }
}

Tel number has a space in the column name, invalidating your query. You need to use quotes around it (although am not sure which).

Well, the error says that your query is wrong, so that's a good place to start. ;) My guess would be because Access is having trouble parsing "Tel number", and surrounding it with brackets would fix the problem:

string myQuery = "INSERT INTO Parent( Name, Surname, Address, Postcode, [Tel number], Email, UserName, Password) VALUES ( '" + TextBox1.Text + "' , '" + TextBox2.Text + "' , '" + TextBox3.Text + "' , '" + TextBox4.Text + "' , '" + TextBox5.Text + "' , '" + TextBox6.Text + "' , '" + TextBox7.Text + "' , '" + TextBox8.Text + "')";

This is assuming "Tel number" actually has embedded whitespace in the database schema. Otherwise it's a typo and you need to remove that space. I mention this as an alternative because UserName doesn't have a space, which suggests either an inconsistent schema definition or a typo in the C# code.

But typically when getting errors like this I'll trace the query or print out the end result that gets run, then copy/paste and run it directly from the database. Often it's easier to debug from there than simply going by the stack trace in C#.
