Add a trigger on select - sql

Question

Is it possible to create a select trigger? I know there are update insert or delete triggers. But select trigger is what I need for a little url shortener application. Everytime a shorturl is hit I'd like to update counter and last access date. A select trigger would be perfect.
select url where code = :code
whould be the one to trigger the trigger.

Ended up doing this:
create function `get_the_url`(c char(7))
returns varchar(255)
begin
declare result varchar(255);
update code
set
hits = hits + 1,
last_used=current_timestamp()
where code = c;
return (
select url
from code
where code = c
);
end
saving this for prosperity and me.
for this table:
create table `code` (
`code` char(5) not null,
`url` varchar(240) default null,
`last_used` datetime not null default '0000-00-00 00:00:00',
`hits` int(10) unsigned not null default 0,
primary key (`code`) using hash,
key `url` (`url`) using hash
) engine=myisam
For those few php folks interested, this is how I populated the table:
<?php
declare(strict_types=1);
$charset ="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNAOPQRSTUVWXYZ1234567890-_.!~*'()";
$size = 8;
function getCode(): string {
global $size;
global $charset;
$length = strlen($charset)-1;
$result =
$charset[rand(0,$length)]
.$charset[rand(0,$length)]
.$charset[rand(0,$length)]
.$charset[rand(0,$length)]
.$charset[rand(0,$length)];
return $result;
}
$db = new \PDO("mysql:dbname=qr","qr","qr");
$insert = $db-> prepare("insert into code(code,url,last_used,hits)values(:code,null,default,default)");
$code = getCode();
$insert->bindParam(':code',$code);
for($i=1000; $i>0; $i--) {
$code = getCode();
$insert-> execute() or die($insert->errorInfo()[2]);
}
and yes, populating this upfront probably makes sense as storage space is cheap and computing power is not.
