Hi:

 

I have a situation where I will be inserting thousands of records into a
table but leaving 2 of it's columns null.  Later on, I will be updating
most of those records and putting real values in  place of those 2
nulls. As for the ones that do not get updated, I want to leave them
null.   My concern has to do with record fragmentation at the time of
update because there's no room to "expand" them to accept the non-null
data.  (BTW, the columns are floating point).

 

Is there a way to initially insert nulls, but reserve space for the
future update (and avoid record fragmentation)?  

Is my record fragmentation concern unfounded?

 

Thanks in Advance !
