Hi,

I am creating a database system where I have a field that is called semester. The values will be similiar to Fall-05, Spring-06 etc. There will be multiple instances throughout all the student entries in the system. What I want to do is query the database to find all the different semesters that exist in the database, but I just need one of each, so I can run another query using these values to show semester totals. Is there a specific MySQL query that can do this operation?

Thanks for your help!
