How to use ExecuteNonQuery() method in ASP.Net c#?

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().

Example:

protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                //Create the connection object
               SqlConnection connection = new SqlConnection(ConfigurationManager.ConnectionStrings["ShoppingZone"].ConnectionString) ;
                try
               {
                   SqlCommand cmd = new SqlCommand("insert into employee values ('zubair', 'male','melapalayam')",connection);
                    connection.Open();
                   //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
                   Response.Write(ex.ToString());
               }
                finally
               {
                   // The finallyblock is guarenteed to execute even if there is an exception. 
                   //  This ensures connections are always properlyclosed.
                   connection.Close();
               }
            }
}
