[GENERAL] Joining more than 2 tables

2001-04-28 Thread Jeff Meeks
Hi, I am trying to join 3 tables with this query select a.id, a.name, sum(b.qty), sum(c.qty) from a, b, c where a.id=xxx and b.id=a.id and c.id=a.id what the sums that get returned look as if they are a cross products of the b and c tables. What is the correct way
