P: n/a

I don't know if it is a bug, but when I try to run to
following query on a DB with 2100 (fonds_tbl) and 6100
(fonds_name_tbl) entries I can see the memory use
increasing and in the end the query is aborted due to
a out of memory message. And I have about 768 MB of RAM.

select * from fonds_tbl where fonds_tbl.isin != fonds_name_tbl.isin

But if I try:

select * from fonds_tbl where not in (select isin from fonds_name_tbl)

it works fine.

Can't remember exactly if those were the statesments but in fact
I just tried to select the entries which are not in both tables.
