sql - Send email from MySQL trigger when a table updated

Question

Consider a table as table2, i like to add a trigger on this table update as

select Num into num from table1 where ID=new.id;
BEGIN
DECLARE done int default false;
DECLARE cur1 CURSOR FOR select EmailId from users where Num=num;
DECLARE continue handler for not found set done = true;
OPEN cur1;
my_loop: loop
    fetch cur1 into email_id;
    if done then
        leave my_loop;
    end if;
    //send mail to all email id.
end loop my_loop;
close cur1;
END;

Is there any simple method to write in the place commented? To send a email to all the email id retrieved from table users.

I am using MySQL in XAMPP(phpmyadmin).

I'm against that solution. Putting the load of sending e-mails in your Database Server could end very bad.

In my opinion, what you should do is create a table that queues the emails you would want to send and have a process that checks if there are emails to be sent and send them if positive.
