execution plan

hey guys,
What comes to your mind if you see a 80% table scan and 1700 estimated cost
in update when your clause is like this?
where auxid >= 1000
but if it is like this,
where auxid = 1000
estimated cost on update is 1.15
Any help would be greatly appreciated.
Thanks,
Neil

d rows vs actual rows
for that search criteria.
