You will not have any problem if any 'X' is not null.
In the case that 'X' coul be null, how are you going to fill it?
like: AA-CC-BBB-BBB- - -
you can have problems with the last spaces, and when you query it is going
to be a nigthmare!.
Consider also that depending of the size of your database you are using 4
characters more.
Why not just format the input/output more readable?
