Hi,
it's me again!

tell this to your bosses:

the problem we have, is that we made a lot of projects with Oracle Hyperion 
business untelligence suite (the old BrioQuery), and we developed them on 
Interbase 5.6; now we migrated a lot of our customers to Interbase 2007 and 
we discovered that these projects don't work because Hyperion generate the 
queries with implicit joins for inner join and explicit joins for outer 
ones.
I don't think I'm the only one with this problem and I don't think you like 
have this defect and remember that this syntax is valid in SQL-92.
Maybe Oracle could change something in its product, but their database works 
fine in this context and I think they don't mind of Interbase, because, I 
repeat, this syntax is standard in SQL-92.

Hi,
Massimiliano.
