SQLnn-compliant does not mean that the language contains everything that is described in the standards, other than the Level 1 base set. It means that *if a feature is implemented* then it is implemented according to the standard.

What's more, standards change from version to SQLnn-compliant does not always mean SQKnn+x compliant. ;-)
