Subject: RE: 9.2.0.4 buffer (sort)
The cartesian is not the problem I am comparing plans on 8.1.7.4 and = 9.2.0.4 both of which do the cartesian (which happens to be the fastest = way to do this query).
select tril_adjustments.unid, tril_adjustments.organization_id,
TO_CHAR(tril_adjustments.start_date, 'YYYY-MM-DD HH24:MI:SS'),
TO_CHAR(tril_adjustments.end_date, 'YYYY-MM-DD HH24:MI:SS'),
tril_adjustments.object_name, tril_adjustments.pricing_type_id,
tril_adjustments.amount, tril_adjustments.low_range,
tril_adjustments.high_range, tril_adjustments.object_type,
tril_adjustments.range_type
from
tril_adjustments, TRIL_JOINS_WRK j2, TRIL_JOINS_WRK j1=20
where
tril_adjustments.object_name =3D j2.join_text=20
and j2.local_id =3D :1=20
and j2.join_number =3D :2=20
and tril_adjustments.organization_id =3D j1.join_text=20
and j1.local_id =3D :3=20
and j1.join_number =3D :4=20
and tril_adjustments.start_date <=3D :5=20
and tril_adjustments.end_date >=3D :6=20
order by tril_adjustments.organization_id asc
=20
"merge join cartesian" is the real clue here. chances are quite good that you have a join condition missing that could provide for a better access path if explicitly stated.
Please re-examine the tables in the statement and look for other joins or filtering conditions.
I did not see the statement in your posting.
