What's the chances of getting recursive queries in for 7.4?

If you mean SQL99 WITH clauses, approximately zero ... unless you
had an implementation you were planning to whip out of your hip
pocket along about now.  Andrew Overholt of Red Hat has been working
on this, but is certainly not going to make the Tuesday feature-freeze
deadline.

I was just wondering who was working on it and what the progress was...?  It
seemed to me that it must have been hacked on for quite a long time now?
Also, are we getting DB2 or Oracle syntax?

Andrew's had the usual quota of corporate demands on his time :-(.
Perhaps he'll weigh in here for himself, but I had thought right along
that getting it done for 7.4 was chancy.

SQL99-spec is the intention.  I believe this is much closer to DB2 than
to Oracle.

Yeah, I had originally thought that I would be able to get it done, but
only sporadic development time leaves me in the usual "where was I?"-"oh
yeah"-"_this_ is what I was going to do next" time-sink and I haven't
progressed as much as I had wanted.  I had been attempting to get the
non-recursive case in before 7.4, but that's not going to happen either.
Sometime this summer for sure.  Sorry.
