Ran into same issue. Relatively new to php and mysql.
It seems PDOStatement wants to bind values as strings, even overriding
the explicit data type! It seems the safest way to use PDOStatements
with integers is to use bindValue, intval() for value and PDO::PARAM_INT
for explicit data type:
$pdoStmt->bindValue(':limit', intval($limit_value), PDO::PARAM_INT);
Here is my test code:
<?
echo phpversion();
$pdoh = new PDO('mysql:host=localhost');
$pdoh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING);
$pdoStmt = $pdoh->prepare('SELECT 1 LIMIT :limit');
$pdoStmt->execute(Array(':limit' => 0));
$pdoStmt->bindValue(':limit', 0);
$pdoStmt->execute();
$pdoStmt->bindValue(':limit', '0', PDO::PARAM_INT);
$pdoStmt->execute();
?>
5.2.6-3ubuntu4.2

The third parameter to bindValue defaults to PDO::PARAM_STR. This is
different than the original bug reporter said, so it must be changed in
the meantime. Because the datatype is PDO::PARAM_STR, the int is cast to
a string and quoted.
It would make sense to use the PHP type to determine the most logical
PDO::PARAM_* type. See also bug #44597, which is essentially the same
problem but with booleans and execute() instead of bindValue().

But you didn't bother updating the version field. Done now..
