Thread: UNION in views

    Hi all,
I am part of the team that's porting the ArsDigita Community System
(ACS), a toolkit to create community-oriented db-backed websites, from
Oracle to PostgreSQL. We call the projet OpenACS.We are thinking of using PG 7.1b for the port (since it'll take some
time, allowing PG 7.1 to mature), because of OUTER JOINs support and
because of a message by Tom Lane that I read a couple days ago where he
said that subselects in the from clause are now supported in the CVS
version of PG. I was wondering if UNIONs in VIEWS will be supported too. Do you have a
time frame for the release of 7.1b? Any additional comments on 7.1
features,drawbacks, caveats, etc, are appreciated.
Thanks,
-Roberto

Already there for 7.1.
        regards, tom lane

I'd actually like to see a view a union.  I have a database where I've split
up each day's data into a separate table.  I had to do this to keep the
number of records to a usable level.  Now, if I want to do a query over the
last several days, I have grief.  I have kludged a system together which
rewrites my sql and (attempts to) handle group by, limit and order by
clauses.  But I'd like to have a cleaner solution.

Any plans?
