Yes, and perhaps others do too. I didn't mean to imply that the last list of features were unique to FirstSQL and didn't want to get into detail arguments about whose recursive support is better.

They are features that improve relational compliance over Standard SQL, and I doubt that other SQL DBMSs provide more than 4.
