Bug description:Different behavior of parameters processing
Description:
------------
PDO::ATTR_EMULATE_PREPARES changes behavior of parameter processing.
When it is enabled multiple occurrences of named parameter work as
expected, but
when it is disabled I get "Invalid parameter number" error.
Test script:
---------------
<?php
$pdo = new PDO('mysql:host=localhost;dbname=test', 'root', '');
$pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false); /// remove this
line and scirpt works as expected
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$query = $pdo->prepare('select :x = :x');
$query->bindValue(':x', 1);
$query->execute();
$t = $query->fetch();
var_dump($t);
$query->closeCursor();
Expected result:
----------------
array(2) {
'\'1\' = \'1\'' =>
string(1) "1"
[0] =>
string(1) "1"
}
Actual result:
--------------
PDOException: SQLSTATE[HY093]: Invalid parameter number in
/srv/http/fucktube/app/test.php on line 7
