Update SQL

I have a page that when someone searches for information.. Every hit that shows up on that page has an SQL update that increases a counter for that particular "record". Now when we have hundreds/thousands of users using the site.. Will this cause some serious problems since most of the users will be using this search and at the same time? That's a lot of db hits all at once isnt it? Rick "Not one of them who took up in his youth with this opinion that there are no gods, ever continued until old age faithful to his conviction." - Plato
