Subject: how control update rows

Hi there,

I'd like to control the rows which are updated. I found useful the option 
RETURNING in UPDATE syntaxt. Can I process the rows wich are returning there 
?

I think to something like that:

SELECT *
FROM (
    UPDATE "T" SET
        "C" = 1
    WHERE "ID" > 100
    RETURNING *
) x

TIA,
Sabin
