I am working on a database for work. It is a processing plant and once a product is complete it is entered into a table. At the end of each shift the workers will be logging out. What I need to figure out is how to just get a total product processed a 12 hr period. The periods will always be either 6:30 am to 6:30 pm or 6:30 pm to 6:30 am. After it is complete it will be added onto a report.
