Question

I need some help with creating an insert statement for an Access 2007 database using C# in VS2008. The current code that I have gives me “ERROR 42000: Syntax error in INSERT INTO statement.” I am not sure what is wrong. I wrote this code based on a working code that I used earlier this year that connected to an ms access table and transfer the database info into an oracle database.

Current code

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.Linq;
using System.Text;
using System.Data.OracleClient;
using System.Data.SqlClient;
using System.IO;
using System.Data.Odbc;
class MainClass
{
static void Main(string[] args)
{
    string connectionString = "Dsn=Northwind 2007";
    string SQL = "SELECT * FROM Orders";
    string sqlins = "";
    OdbcConnection conn = new OdbcConnection(connectionString);

    OdbcCommand cmd = new OdbcCommand(SQL);
    cmd.Connection = conn;
    OdbcCommand cmdnon=new OdbcCommand(sqlins,conn);
    try
        {

        conn.Open();

        OdbcDataReader reader = cmd.ExecuteReader();
        while (reader.Read())
        {
            Console.Write("OrderID:" + reader.GetInt32(0).ToString());
            Console.Write(" ,");
            Console.WriteLine("Customer:" + reader.GetString(1).ToString());
            cmdnon.CommandText = "INSERT Commonstation ( S1Flow,S2Flow,S3Flow,S4Flow) VALUES (9999,999,999,999)";
            int rowsAffected = cmdnon.ExecuteNonQuery();
            Console.WriteLine(rowsAffected);
        }
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.InnerException.ToString());
    }
    finally
    {
        reader.Close();
        conn.Close();
    }
}
}

Try:

cmdnon.CommandText = "INSERT INTO Commonstation...

At least, that’s what the error is telling you.
