Drupal 6.x

Hii,
i want to update my product price to 40% and i am using in ubercart. I have created a query select sell_price+(sell_price*0.4) from uc_products. This is only just a select query but i want to update all product price. It seems that i have to use loop so that it will update all product price, but problem is my mysql coding is not so good. So is there any one who can help me out in loop coding or suggesting me best way to accomplish this task.

I have a log entry with the "anonymous" user, like that :

content | 2014-xx-xx xx:xx | story: updated my title. | Anonyme

Is it really an Update ???? Or what that's mean ?

Thanks for Reply.
