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

Modification is driven by index on that column and you should check estimated rows vs actual rows
for that search criteria.
