I just recieved SQL in a Nutshell from O'Reilly. I bought the book
because it covers the SQL99 standard. It's my understanding that this
is the most recent SQL standard. Am I correct about this? What is the
current status of SQL standards? What is the most recent approved
standard, and what aspects of SQL are still under discussion?
I ask, because I notice that the book doesn't mention recursive unions.
In fact I don't see mention of unions at all, nevermind recursive
unions, so this may simply be an oversight. However, since this is a
feature I've really been looking forward to, I'm now wondering if I'm
hoping in vain.
What organization is currently responsible for drafting SQL standards?
How can I obtain publications describing those standards? Is there
anything comprehensive and definitive online?
