Subject Changing field all places
Author Michael Vilhelmsen <Michael.Vilhelmsen@M

I have a table (MyTable) with a primary key.
This primary key is of type varchar(30) not null.

Now one of our customers want to change this.
My problem is, that it is linked to other tables.

Can I do smething, to change to condition of this field, so that upon
change the DB will change it in all places where it is being
reference as a foreign key ?
