This is a problem I've run into with pdo_dblib, but the fix would involve
touching PDO Core. I'd appreciate any feedback on potential negative
interactions with other drivers, as well as which PHP version I should
target the fix for. It's arguable whether this is a bug or a feature
request. If I don't hear from anyone, I'll keep it to master to give others
the most time to prepare.
Thanks,
Adam

Subject: [PHP-BUG] Bug #73234 [NEW]: emulated statements let value dictate
parameter type
To: php-b...@lists.php.net
From: adambaratz
Operating system:
PHP version: Irrelevant
Package: PDO Core
Bug Type: Bug
Bug description:emulated statements let value dictate parameter type
Description:
------------
See test script. I would expect both statements to return NULL. Given
the looseness of PHP's type system, this feels appropriate and safer.
There's a related issue where numbers can end up treated as strings.
Test script:
---------------
$db = new PDO(...);
$stmt = $db->prepare("SELECT :null");
$stmt->bindValue(':null', null, PDO::PARAM_NULL);
$stmt->execute();
var_dump($stmt->fetchAll()); // NULL
$stmt = $db->prepare("SELECT :null");
$stmt->bindValue(':null', 0, PDO::PARAM_NULL);
$stmt->execute();
var_dump($stmt->fetchAll()); // 0
