1) No. You must add third column that unically describes a person (primary
key). E.g. there will more than one john smith.
2) And my first answer is the answer on your first question:
table - fammem
personid famid memid
1 1 1
2 1 3
3 32 4
4 5 4
5 3 6
6 4 1
sql:
insert into fammem( famid , memid) values (5, 1);
insert into fammem( famid , memid) values (1, 1);
insert into fammem( famid , memid) values (3, 3);
...
the personid is autoincr. field.
3) You shouldn`t use INNER JOIN, you may use simple SELECT:
select fammem.*, family.name, members.name from family , fammem, members
where family.id = fammem.famid and fammem.memid=members.id
4) uffff....
