Hello, Could somebody please try to help me with this problem?
I.e., I want to pick the 5 largest entries from table1 and show them alongside a new index column that tells the position of the entry. For example: a | b -------- 82 | 5 79 | 4 34 | 3 12 | 2 11 | 1
Short of enumerating those results in your application, the easiest approach is probably to wrap your query in a join with generate_series like so:
SELECT a, s.b FROM ( SELECT a FROM table1 ORDER BY a DESC LIMIT 5 ) AS t1, generate_series(5, 1, -1) AS s(b) Alban Hertroys -- Screwing up is the best way to attach something to the ceiling. !DSPAM:737,4adaee3411688629581426! -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
