It seems there's something wrong in the design of your db : Don't you have
another table containing name attribute as primary key which you could refer
as foreign key in staf_xxxx ?
I don't know how to implement what you want to do, except perhaps
implementing your own referential control in procedural sql functions fired
Anyhow, it is better design pattern to use sequential number without any
business meaning as primary key.
