Problem with dataset to sql
<pre><code>{ 
   string selectDesc = @" SELECT     [Descripion id], [Sub Collection FROM      Descripion   ";

    DataSet dsD = new DataSet();
    SqlCommand comD = new SqlCommand();
    comD.Connection = con;
    comD.CommandText = selectDesc;
    SqlDataAdapter daD = new SqlDataAdapter();
    daD.SelectCommand = comD;
    SqlCommandBuilder cbD = new SqlCommandBuilder(da);
    daD.Fill(dsD, "Descripion");
    DataRow new_row_Desc = dsD.Tables[0].NewRow();
    new_row_Desc["Descripion id"] = 58589;
    new_row_Desc["Sub Collection"] = TextBox18.Text;
            dsD.Tables[0].Rows.Add(new_row_Desc);
    daD.Update(dsD.Tables[0]);
}
</code></pre>

<p>I am getting this error:</p>

<blockquote>
  <p>Update requires a valid InsertCommand when passed DataRow collection with new rows.</p>
</blockquote>

<p>What is the problem?</p>
