I have a JOB table, with two interesting columns:

Creation Date
Importance (high - 3, medium 2, low - 1).

A JOB record's priority calculated like this:

Priority = Importance * (time passed since creation)

The problem is, every time I would like to pick 200 jobs with highest priority, and I don't want to resort the table. Is there a way to keep rows sorted?

I was also thinking about having three tables one for High, Medium and Low and then sort those by Creation Date.
