> When issuing a query like "SELECT NULL" a NotImplemented exception will be 
> generated.
> Digging a little deeper reveals that for the NULL a TT_UNDEFINED tag is 
> obtained. At the SQLDataSerialization::getDeserializer() a NotImplemented 
> exception is generated for this tag.
> A very simple solution for this is to return NULL for TT_UNDEFINED because 
> later at the deserializing the field data, the deserializer will not be used, 
> because the field is null.
> Another solution would be to create a dummy deserializer that does nothing, 
> but throws an exception.
