For this kind of thing, I usually build the whole statement and concatenate
my list into it.
But, I think you can do it without the function. Something like ...
select *
from test2
where symbol in (
select distinct
symbol
from test
where ...
)

Subject: is it possible to use a function to
8.1.7.4 Solaris 9
What I want to do is build a In list and feed it to a query:
select * from test2 where
symbol in ( select test_function('IBM') symbol from dual);
One symbol comming out of the function works fine. multiples do not
the select test_function('IBM') from dual works just fine.
I cannot get the outer query to work.
What am I missing?
Thanks,
Kathy
