#48314 [NEW]: PDO_MySQL doesn't use prepared statements
From: vrana@php.net
Operating system: Windows
PHP version: 5.2.9
PHP Bug Type: PDO related
Bug description: PDO_MySQL doesn't use prepared statements
Description:
------------
It seems that PDO_MySQL doesn't use prepared statements even with disabled
PDO::MYSQL_ATTR_DIRECT_QUERY. If the prepared statements would by used then
the binary data passed in the example wouldn't cause a parse error.
MySQL version: 5.1.26
Reproduce code:
---------------
<?php
$pdo = new PDO("mysql:host=localhost", "ODBC", "");
$pdo->setAttribute(PDO::MYSQL_ATTR_DIRECT_QUERY, false);
$pdo->exec("SET NAMES gbk");
$stmt = $pdo->prepare("SELECT ?");
$stmt->execute(array(chr(0xbf) . chr(0x27)));
print_r($stmt->errorInfo());
?>
Expected result:
----------------
Array
(
[0] => 00000
)
Actual result:
--------------
Array
(
[0] => 42000
[1] => 1064
[2] => You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use near
''¿\''' at line 1
)
