Actually I think Oracle recommends that NULL columns should be placed at the
end of the row for optimal storage of the row in the block.

It makes no difference in performance where the not null columns are placed.
Why do you want to go to the headache of modifying the table structure for
something so trivial?

Hi DBA's,
Greetings...
In some of application tables, i found not null columns are appeared at the
last.
So, how can i re-arrange by the way i can make the not null columns are in
the earliest of the table.
Is the only way to re-create the tables accordingly, or any other best
methods are there?.
Thanks.
Regards,
Nirmal.
