The table "student" probably does not even exist in your master database. Connect to the correct database.
You will never, ever update anything using a select statement....

Question 1) What is the exception
Question 2) Why are you not setting the update command? The update method runs what what ever SQL code is set to be the update command.
Question 3) Why not use a Typed Dataset based around the XML/Database table schema?
Question 4) What is the format of the XML document?

There are a lot of unknowns and without more information we cannot provide much help.

hi, Try this ...

protected void button1_Click(object sender, EventArgs e)
   {
       SqlCommand command;
       SqlDataAdapter adpter = new SqlDataAdapter();
       DataSet ds = new DataSet();
       XmlReader xmlFile;
       string sql = null;
       string Product_Name = null;
       string path = MapPath("XMLFile.xml");
       xmlFile = XmlReader.Create(path, new XmlReaderSettings());
       ds.ReadXml(xmlFile);
       int i = 0;
       con.Open();
       for (i = 0; i <= ds.Tables[0].Rows.Count - 1; i++)
       {
           Product_Name = ds.Tables[0].Rows[i].ItemArray[1].ToString();
           sql = "insert into tab1 values('" + Product_Name + "')";
           command = new SqlCommand(sql, con);
           adpter.InsertCommand = command;
           adpter.InsertCommand.ExecuteNonQuery();
       }
       con.Close();
   }
