Ed,
When I face this, I build a little BASIC program which builds a UNION
file which is keyed by file * item and then I do the Query against
that file. You could probably build the UNION file from triggers and
always keep it current.
Here's how it works:
If DAILY.FILE has three

always wind up writing Basic to do it, making independent selects from
each file and

A few months ago someone mentioned that a paper was forthcoming from IBM re
recommendations on running UniData on a SAN. Does anyone know the status of
this paper? I don't see anything out there yet.

Not sure if sql is an option for you... but there is a union construct
in it. Both files have a '1' id. The ids are not shown in second
example.

Question for everyone then: Should IBM invent a method to extend the Query
languages of UniData/UniVerse to do this 'Temporal File' - a Cross Data
File SELECT/LIST/SORT?
That is, should the logic for handling multiple datafiles with a common
dictionary basis be 'native' to the processes? Would

I'd vote for that! Here's the language I'd suggest:
SORT, LIST, SELECT, SSELECT (at minimum) should allow for data in
multiple data levels as an option. The keyword SPANNING would be used to
indicate which data levels or SPANNING ALL for all data levels. When
Spanning is used,

I was at a U2 Convention in Anaheim a few years ago, the first year U2
was part of the IBM. I had an opportunity to speak to a couple U2
engineers, sorry I've forgotten now who they were. I asked them if
they'd ever considered implementing this. Their reaction was pretty

I vote no. The UV/UD query language is fundamentally designed to work
against one file with correlatives/I-types pointing to any other tables
from which we require related data. This is something at the core of our
environment. The problem here is, shall we say, problematic database
design.
I see you started the ball rolling on this... Does this also need to go to
U2AskUs?
That is, how much influence does BnB have on product direction?
Or does IBM need to hear this request directly from multiple VARs? (Which
we could probably coordinate in a day!)

I'd have to second David on this. I wish in Unibasic there was a
program/function to create temporary user files that get cleaned-up on exit and
let UD/UV determine the area to create these on the file system.

Does UV have multi-level files? I thought it was restricted to UD and even
UD documentation doesn't recommend the structure because it's too Pick-like.

Which we were you speaking of? Just kidding, seemed like such a great

Anyway, since it already exists in Universe my guess would be that
implementing multi part files would be easier, and less kludgey, than
implementing some sort of file spanning, temp file
