I'm a novice SQL user, and I'm confused by an apparently arbitrary limitation on multiple inner joins.
select * from aa inner join bb using (i) inner join cc using (j); SQL error: cannot join using column j - column not present in both tables
I suggest you work around the problem by coding the select like this:
select * from aa, bb, cc where aa.i=bb.i and cc.j=aa.j;
