using (SqlConnection conn = new SqlConnection(SqlHelper.StudentConnectionString))
{
string sql = "select t_stuUser.ID, t_stuUser.stuNumber, t_stuUser.userPassword, t_stuUser.realName, v_stuUser.className, v_stuUser.departmentName "
+ "from t_stuUser,v_stuUser where t_stuUser.stuNumber=@UserName and t_stuUser.userPassword=@UserPwd and v_stuUser.stuNumber=@UserName";
SqlCommand cmd = new SqlCommand(sql, conn);
SqlParameter pUserName = cmd.Parameters.Add("@UserName", SqlDbType.VarChar, 30);
SqlParameter pUserPwd = cmd.Parameters.Add("@UserPwd", SqlDbType.VarChar, 150);
pUserName.Value = Request.Form["UserName"];
pUserPwd.Value = Request.Form["UserPwd"];
conn.Open();
SqlDataReader sdr = cmd.ExecuteReader(CommandBehavior.CloseConnection);
if (sdr.Read())
{
Session["UserID"] = Convert.ToString(sdr["ID"]);
Session["StuName"] = Convert.ToString(sdr["realName"]);
Session["StuNumber"] = Convert.ToString(sdr["stuNumber"]);
Session["Academe"] = Convert.ToString(sdr["departmentName"]);
Session["ClassName"] = Convert.ToString(sdr["className"]);
Response.Redirect("MyOrder.aspx"); // 登錄成功
}
else
{
Response.Redirect("Default.aspx"); //登錄失敗，用戶名或密碼錯誤
}
}
