DBALException doesn't forward the SQL exception code

      PDO exceptions carry the SQL error code. However DBALException doesn't forward any error code from the SQL exception.

      Here is a (really poor/quick) example of usage:

      try {
      } catch (DBALException $e) {
          if ($e->getCode() === 23000) {
              echo '';
          } else {
              throw $e;

      I think I found where the problem is:

      public static function driverExceptionDuringQuery(\Exception $driverEx, $sql, array $params = array())
          $msg = "An exception occurred while executing '".$sql."'";
          if ($params) {
              $msg .= " with params ".json_encode($params);
          $msg .= ":\n\n".$driverEx->getMessage();
          return new self($msg, 0, $driverEx);

      In return new self($msg, 0, $driverEx);, the exception is created with an error code of 0.

      Is there a reason for this: is that that the driver exception may not always have a defined error code? (for example if the sql driver is not PDO or the SQL system doesn't support that, but in this case then the error code would be 0 would that be a problem?)
