I will in the 'student' table allow an 'id' INTEGER PRIMARY KEY
AUTOINCREMENT .
Every student have an identification number and such a number is 13 digit
long. But some idnumber start with leading zero so I think to it is better
to have this filed as TEXT to keep those leading zeros at the beginning of
the 'idnum'. I do not want to do calculations with 'idnum' values.
