update with select

Hi,

Is it possible to rewrite this query to use a single SELECT?

UPDATE product SET
price_min = (SELECT min (price) FROM subproduct WHERE subproduct.product
= $ID),
price_max = (SELECT max (price) FROM subproduct WHERE subproduct.product
= $ID)
WHERE id = $ID

Thanks.

Try:


UPDATE product SET price_min = ss.min_price, price_max = ss.max_price
from ( select min( price) as min_price, max( price) as max_price
  FROM subproduct WHERE subproduct.product = $ID) as ss
WHERE id = $ID;
