It might be revealing to trace what WebFocus is doing that means it can't use a
view (allegedly).
From what little documentation there is publically available, who knows what
the "SQL Translation" layer does.
But it's not impossible that it's doing some sort of lookup against something
like USER_TABLES as it "translates SQL to an internal, canonical form" and then
back to "specific SQL dialects supported by proprietary RDBMSs" - "whatever".
However, it also looks like it can operate with straight "SQL Pass through" so
maybe this would avoid any source of the problem.
But, my first reaction is that some sort of lookup is involved and that causes
the problem - find the lookup and you're at least part of the way to thinking
about ways to avoid the issue.
Cheers,
Dominic

Subject: WebFocus and Oracle Views
Guys and Gals,
I've a WebFocus developer here who is telling mew that he cannot use a
view to query data from the database. The app developers have created and
tuned these views to the n'th degree so that they provide correct data quickly
( I have to pat these folks on the back as they really did work hard on them).
Anyway this duhveloper wants to create MV's out of them so that "WebFocus will
behave as expected" and he is absolutely adamant about it to the point that he
has not started his work because "we won't let him create his MV's". BTW: he
wants to refresh these at 1 minute intervals and they will require a full
refresh. I've searched the WEB and even talked to a couple of others that I
know who've used WebFocus and can't find anything that in any way substantiates
what this person is telling me. In a bit of frustration with him I'm turning
to the list to see if any of you have ever heard or seen anything along these
lines. All replies are appreciated. As I understand it it's WebFocus 7.0 on
Linux RH5 using an Oracle 11.1.0.7 backend database also on RH.
Thanks in advance.
