Question

I’m trying to select some fields from my database and store them as a variable so I can use them to display data on my page. So far I have this:

  protected void DefaultGrid_SelectedIndexChanged(Object sender, EventArgs e)
    {
        string firstName;
        GridViewRow row = DefaultGrid.SelectedRow;
        int id = Convert.ToInt32(row.Cells[9].Text);
        string checkStatement = "Return fName FROM SecureOrders WHERE IdentityColumn LIKE @identity";
        using (SqlConnection connection = new SqlConnection(connectionString.ToString()))
        using (SqlCommand _check = new SqlCommand(checkStatement, connection))
        {
            _check.Parameters.Add("@identity", SqlDbType.Int).Value = id;
            connection.Open();
            _check.ExecuteNonQuery();
            connection.Close();
        }

I’m wondering how I should alter this so that I can save the field fName in the variable called firstName. Am I on the right track?

Answer 1

You can write firstName = (string) _check.ExecuteScalar()
