hi,
I'm having troubles with inheritance too. I've created a table,
"person", and it has a field "code" as its primary key.
After, I've created a table, "student", that inherits person. I wanted
too use the column person.code as the primary key in the students
table too, but I've noticed that, when I insert a student, the
uniqueness of the primary key is no granted. for example, I can insert
two students.code = "1"
How can I inherit the primary key too??
thankx,
Camila
PS: Sorry about the bad english, i'm brazilian
