U kunt deelnemen aan de subquery en doe een UPDATE :
UPDATE table_name t2
SET t2.rank=
SELECT t1.rank FROM(
SELECT company,
direction,
type,
YEAR,
MONTH,
value,
rank() OVER (PARTITION BY direction, type, YEAR, MONTH ORDER BY value DESC) AS rank
FROM table_name
GROUP BY company,
direction,
TYPE,
YEAR,
MONTH,
VALUE
ORDER BY company,
direction,
TYPE,
YEAR,
MONTH,
VALUE
) t1
WHERE t1.company = t2.company
AND t1.direction = t2.direction;

Of,
Je zou MERGE . kunnen gebruiken en bewaar die zoekopdracht in de USING clausule:
MERGE INTO table_name t USING
(SELECT company,
direction,
TYPE,
YEAR,
MONTH,
VALUE,
rank() OVER (PARTITION BY direction, TYPE, YEAR, MONTH ORDER BY VALUE DESC) AS rank
FROM table1
GROUP BY company,
direction,
TYPE,
YEAR,
MONTH,
VALUE
ORDER BY company,
direction,
TYPE,
YEAR,
MONTH,
VALUE
) s
ON(t.company = s.company AND t.direction = s.direction)
WHEN MATCHED THEN
UPDATE SET t.rank = s.rank;
Voeg vereiste voorwaarden toe aan de ON-clausule.
