You know what they say about 'assuming'? You make an 'ass' out of
'u' and 'me'... :) (ok, no offence)

Back to the subject:
No, I don't ... I use IBO in InterBase Workbench and people just enter
their SQL statements and press 'run'. So I really have no control over
the key links...

But I guess I can create the variation and put in DB_KEY in the select
myself - but why isn't IBO doing this? When I did my tests with the
statement, I couldn't find DB_KEY in the select list... When does IBO
put DB_KEY in the select (I have seen it happen) and when does it
not? (and why)
