Re: Finding rank of a single record

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

P.S.: Here again my tables, I'm trying to get a rank for 1 user there:
