Sorry Rob, but it fails with:
pref=> select * from (
select u.id,
u.first_name,
u.city,
m.money,
rank() over (order by money desc)
from pref_users u, pref_money m where
m.yw=to_char(current_timestamp, 'YYYY-IW')
) all_ranks ar
where ar.id='OK138239987797';
ERROR: syntax error at or near "ar"
LINE 9: ) all_ranks ar
^
Do you have a doc pointer for me here?
I've forgotten to mention that I'm using PostgreSQL 8.4.5
Regards
Alex
P.S.: Here again my tables, I'm trying to get a rank for 1 user there:
