PECL module is not maintained. Will try to fix in master. 

This only affects Sybase ASE as it does not have the same implicit conversions 
supported by MS SQL Server.

Binding variables according to ZVAL type or specific binding type may result in 
BC breakage.

Works in trunk with SQL Server 2008.

require("php_pdo_login.php");
$db = new PDO($dsn,$user,$pass);
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

$sql = "SELECT x from (select cast(1 as int) as x) as tab where x = ?";
$sth = $db->prepare($sql);
$sth->execute(array(1));
while ($row = $sth->fetch(PDO::FETCH_ASSOC)){
    print_r($row);
}

All PDO_DBLIB binds are done as strings. To quote one of the PDO authors: 
"...strings give the greatest fidelity...". There is no formal specification 
for how PDO *should* bind PHP zvals to SQL Variables. This may change in the 
future.

The workaround would be to bind:
   :myVar
as
   cast(:myVar as int)

Unfortunately, it does not work even with bindParam(..., PDO::PARAM_INT). 

I've tried many (all?) potential solutions, but did not found any, except using 
convert()

bindParam() should allow you to force it to handle it as an integer.

I must admit, I find it frustrating that you can't simply specify the parameter 
types during the prepare as in DB/MDB2 where you just pass an array of types: 
array('integer', 'boolean') etc.

Hope that helps.
