Locking a FIELD in mysql?

Is it possible to lock a field in MYSQL like say the category field for and individual record.........MAYBE even a total record to not be overwritten............I am open to all options but just want to LOCK the category field once some due diligence has been done to add like 6 categories..............

SO OVER THE LOSS OF THIS INFORMATION...........
