I was thinking of an implementation method like lastInsertId(), but there is certainly another way to use a subclass. Personally, I was thinking of implementing, for example, SQL99-compliant (included) functions in PDO Core Class, and vendor-specific original functions in subclasses. However, I don't have a strong opinion on how they should be used, as there is still not much precedent for subclasses. I agree with you that it should be a consistent implementation. I'm not sure if all incompatible features should be implemented in subclasses, or just vendor-specific features, but at least yes. There should be consistency. Regards. Saki
