Saved procedure fails while updating

Question

I am using the SQL Server driver for PHP to connect to SQL Server 2008 Express. Right now I am trying to replace all SELECT, UPDATE and INSERT statements with stored procedures. This works great for SPs that simply contain a SELECT statement. But now I tried to do this with the update, and I continue to receive the error message "Executing SQL directly, without cursor." I can cause a fine SP from Management Studio with the same parameter values.

Any ideas?

Greetings Alex

EDIT: here is one update procedure. The funny thing is that the procedure actually performs perfectly and updates the data as intended. But it still returns an error leading to an exception.

First, the PHP code crashes:

if (! $this->Result = sqlsrv_query($this->Conn, $strQuery, $arrParameters, array("Scrollable"=>SQLSRV_CURSOR_STATIC)))
{
    $this->sendErrorMail($strQuery, $arrParameters);
    throw new Exception(4001);
}
