Re: Ambiguous error on view

I found that
"
CREATE VIEW allops AS
SELECT acc1.operator.operatorid, acc1.operator.accountid,
acc1.operator.name, acc2.operator.operatorid, acc2.operator.accountid,
acc2.operator.name
FROM acc1.operator, acc2.operator
WHERE (acc1.operator.active = true OR acc2.operator.active = true);
"
works for the ambiguous errors. But there are identical column names in the
view (operatorid, accountid, name, operatorid, accountid, name) witch
obvious fires
an error "ERROR: column "operatorid" duplicated"
So how to merge the data from the different schema's in one column in the
view?

The global / symbolic statement of what I wnat to do is
SELECT operatorid FROM acc1.operator, acc2.operator,...... WHERE active =
true;
Are there perhaps other ways to do this if the views don't work?
