I have a problem that I figure I can solve by learning sql and I would love to know if it is possible. I work for a small business which would like to track the time each employee spends on a job so that job can be billed accordingly. Here is my thoughts on what I need. I am using a scanner so that each employee can scan an ID tag that would disconnect them from any other job, scan the job they are about to work on, this would start a timer for that job. So is this possible and if so how can I start this?
