Description:
------------

I can't retrieve stored procedure return values

Reproduce code:
---------------
$sth = $DB->prepare('exec proc_getDeviceNumByHdType :inpara,:usetable,:num');
$sth->bindParam(":inpara", $para, PDO::PARAM_STR);
$sth->bindParam(":usetable", $paraTable, PDO::PARAM_STR);
$sth->bindParam(":num", $return, PDO::PARAM_INT|PDO::PARAM_INPUT_OUTPUT,1);
$sth->execute();

	create procedure [dbo].[proc_getDeviceNumByHdType] 
		@hdtype as varchar(256),
		@usetable varchar(50),
		@num int output 
	AS
	begin
		DECLARE @sql Nvarchar(1000)

		SET  @sql = N'SELECT @num=COUNT(*) from  '+CAST(@usetable AS NVARCHAR(50)) 
		EXECUTE sp_executesql @sql,N'@num int output',@num output
	end

Expected result:

Can confirm this on Linux.

PHP 5.2.6, connecting to MSSQL 2000 via freetds 0.82RC4

Guys please fix that I had to revert back to mssql_* functions for calling stored procedures. So Now half of project uses PDO the other half the old functional style...

I can confrim this on MySQL and PostgreSQL as well.  No PARAM_INPUT_OUTPUT values get bound through PDO when running a stored 
procedure.

This is happening for me in 5.3.1., using Pdo_Dblib.  Trying to call a stored procedure on SQL Server 2005 server.  Cannot retrieve a value.

PHP version 5.3.1
Using Pdo_Dblib
Linux:  2.6.24-24-server SMP x86_64 GNU/Linux

PHP Code:
----------------------------
/** SNIP. Set up a valid $db here! **/

$return_value = 999;

$sth = $db->prepare("EXEC dbo.opsp_Test ?");
$sth->bindParam(1, $return_value, PDO::PARAM_STR | PDO::PARAM_INPUT_OUTPUT, 4);
$sth->execute();

echo "$return_value\n";

Return value ALWAYS comes back as 999, no matter what variations I try in bindParam call.

Here's my Stored Procedure:
---------------------------
CREATE PROCEDURE opsp_Test 
	@TheOutputValue int OUTPUT
AS
BEGIN
	SET @TheOutputValue = 11
END

I can confirm that the same issue is present in version 5.3.3. 

The value of $result in the following code snippet will not be changed after the SP is run (even though the procedure returns a value when run from SQL Server Management Studio / freetds / or via mssql_query()

$result = "";
$stmt = $pdo->prepare("exec sp_nextSerialNumGet ?")
$stmt->bindParam(8, $result, PDO::PARAM_STR|PDO::PARAM_INPUT_OUTPUT, 25);
$stmt->execute();
echo $result; // empty 

OR 

$execArray = array(':result' => "");
$stmt = $pdo->prepare("call sp_nextSerialNumGet (:result)");
$stmt->execute($execArray);
echo $stmt->fetch(); //empty, var_dump($stmt->fetchAll()) show array (0) {}
