Assigning the same parameter value multiple times in pdo execute

Question

I originally had an SQL statement, this:

SELECT *, COUNT(friend_one) AS pending_count , COUNT(friend_two) AS requests_sent   
FROM friends
WHERE friend_one OR fr         


        

Answer 1

Using PDO you have the ability to use named parameters, however in your question you want to use 1 parameters for multiple values and that means emulation has to be on:

$db->setAttribute(PDO::ATTR_EMULATE_PREPARES, true);

Now you can do the following:

$stmt = $db->prepare("SELECT * FROM table WHERE userid = :userid AND userid = :userid");

$stmt->excecute([
  ':userid' => 1
]);

Resulting in:

"SELECT * FROM table WHERE userid = 1 AND userid = 1"
