Uh, yes, that's what I said, and that's what the JavaDoc says. Which implies that there's a difference between "JDBC SQL grammar" and "native SQL grammar." But it's completely silent on what exactly "JDBC SQL grammar" is, and how it would differ from native grammars.

RRN is not an SQL concept.

Quite. And likewise, "LIMIT" appears to be a MySQL extension that a number of other systems adopted, while still others call it "TOP." All of this presumably because SQL standards appear to have been originally set to the lowest common denominator for every major database engine out there at the time. And may the Implementor of the Universe save us from database system architects who leave out something so seemingly obvious as RRNs (it's been a while, but I'm pretty sure that the classics, like ISAM and VSAM, have RRNs).

What, your Chinese guys don't know this?

Not their project, and they've got more than enough on their hands.
