hi,
if I have column order_id(int(4)) null do I have to index it too. I'm
going to use it ONLY for sorting records.
It depends a lot on how much data is in the table, etc etc. An index will make sorting
more efficient in the general case when you have a decent amount of data. But it's
hard to be specific with so little information.
