Do.aspx.cs
public partial class Do : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection("Data Source=7E2DF151D5144A0\\SQLEXPRESS;Initial Catalog=TicketBook;Integrated Security=True");
con.Open();
SqlCommand cmd = new SqlCommand("update Seat set i_SeatState =@seatState where c_SeatCode=@seatCode", con);
cmd.Parameters.AddWithValue("@seatState", "1");
cmd.Parameters.AddWithValue("@seatCode", "S006");
cmd.ExecuteNonQuery();
con.Close();
}
}
