How to use ExecuteNonQuery() method in ASP.Net c#?, someone asked me to explain?

In this article we will discuss, how to use ExecuteNonQuery () method in ASP.Net c#. When we want to perform insert, update or delete by using ExecuteNonQuery().


protected void Page_Load(object sender, EventArgs e)
            if (!IsPostBack)
                //Create the connection object
               SqlConnection connection = new SqlConnection(ConfigurationManager.ConnectionStrings["ShoppingZone"].ConnectionString) ;
                   SqlCommand cmd = new SqlCommand("insert into employee values ('zubair', 'male','melapalayam')",connection);
                   //Since we areperforming an insert operation, use ExecuteNonQuery()
                   //method of thecommand object. ExecuteNonQuery() method returns an
                   //integer, whichspecifies the number of rows inserted
                   int rowsAffected =cmd.ExecuteNonQuery();
                   Response.Write("InsertedRows = " +rowsAffected.ToString() + "<br/>");
                catch (Exception ex)
                   // HandleExceptions, if any
                   // The finallyblock is guarenteed to execute even if there is an exception.
                   //  This ensures connections are always properlyclosed.
