Re: Creating view, showing only data whithout connceted data
If each order gets one report, then the object table foreign key should reference the order table, And you'd write ..
select ...
from object
join order using(objectid)
left join report using(orderid)
where report.orderid is null;
Those last two lines implement an exclusion join. Read about 'em.
