An easier approach is to add two columns. LockedBy and LockedOn. When a user begins an edit, lock the record recording the ID and the Time. When they commit remove the lock. Don't let anyone edit the record if it has a lock, or let them see who locked it when and force remove the lock. This way you can also expire locks that are X minutes old, or when a users session ends, remove all there locks. I've used this approach before and it works rather well.
