Access SQL syntax error when using OleDbCommandBuilder

Question posted 2013 · +3 upvotes

I am going to INSERT data in Access Database using OleDbDataAdapter in C# but i got an error with message Syntax Error in INSERT INTO Command

BackgroundWorker worker = new BackgroundWorker();
OleDbDataAdapter dbAdapter new OleDbDataAdapter();
OleDbConnection dbConnection = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=E:\PMS.mdb");
worker = new BackgroundWorker();
worker.WorkerReportsProgress = true;
worker.DoWork += InsertJob;
worker.ProgressChanged += InsertJobCompleted;
worker.RunWorkerAsync(args);

And InsertJob Function is:

private void InsertJob(object sender, DoWorkEventArgs e)
{
     var args = (InsertJobArgs)e.Argument;
     try
        {
            dbAdapter.SelectCommand = new OleDbCommand("SELECT * FROM Sheet", dbConnection);                
            dbAdapter.Fill(args.DataTable);
            var builder = new OleDbCommandBuilder(dbAdapter);
            var row = args.DataTable.NewRow();

            row["UserName"] = args.Entry.UserName;
            row["Password"] = args.Entry.Password;
            args.DataTable.Rows.Add(row);

            dbAdapter.InsertCommand = builder.GetInsertCommand();               
            dbAdapter.Update(args.DataTable);
            builder.Dispose();
        }
        catch (Exception ex)
        {
            args.Exception = ex;
            worker.ReportProgress(0, args);
            return;
        }
        worker.ReportProgress(100, args);
}

I recieve Error on line : dbAdapter.Update(args.DataTable);

I tried to debug it with visual studio and found that All the InsertCommand Parameters Values are null

And I tried to insert it manually by this code before call to dbAdapter.Update(args.DataTable);

dbAdapter.InsertCommand.Parameters[0].Value = args.Entry.UserName;
dbAdapter.InsertCommand.Parameters[1].Value = args.Entry.Password;
