Add the where-clause "where field1 != 0" if there's any chance that any of the rows already has field1 = 0.

Hi all:

I need to update every row 30mil-rows table. I have dropped the indices and running the update in parallel:

update /*+ parallel (degree 8) */ table_name set field1=0;

Is there anything else I could to to speed up this process. I don't think I can do an update in nologging mode. I'm running 8.1.7.4

thanks for any advice.
