MySql Question

    Is it possible to produce a derived record from a table.
    I have a course table
    it contains a filed which represents the max no. of participants.

    I need a field to tell me how many places are left

    It could easily do this by returning the th emax number minus the total record-count.
    but can I create a derived record to throw this value into a table.

    thank you.
