I beg to differ.
Storage as well as performance is effected if nulls are not at the end of a
table.
Although it is not a HUGE concern, it is certainly fine tuning.

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.
