Session dataset 怎么会一定要转成int类型的

[tangbofu]

DataSet master = new DataSet();
DataSet detail = new DataSet();
//if (Session["master"] != null)
Session.Remove("master");

//if (Session["detail"] != null)
Session.Remove("detail");

SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["nb_flagConnectionString"].ToString());
conn.Open();
SqlDataAdapter oada = new SqlDataAdapter("select * from bln_mf where bl_no=" + Request.Params["bl_no"].ToString(), conn);
oada.Fill(master);
Session.Add("master", master);
oada.SelectCommand.CommandText = "select * from bln_tf where bl_no=" + Request.Params["bl_no"].ToString();
oada.Fill(detail);
Session.Add("detail", detail );



红色部分出错 将 varchar 值 'aa121212' 转换为数据类型为 int 的列时发生语法错误。
