Hi.
I want to update a table based on data in another
table. Something like:
update table1 a set f1 =
(select f2
from table2
where table2.f3 = table1.f3
and table2.f4 = table1.f4);
this seems to work, but generates a lot of redo logs.
So I tried to add NOLOGGING. Alas, seems like
NOLOGGING
NOLOGGING does not work on update, period. has nothing to do with
aliases.

Your update is updating all rows in table1. Is that
what you want ?
nologging only works with direct path insert, not with
update.
