am Thu, dem 22.02.2007, um 12:20:12 +0100 mailte Rafa Comino folgendes:

Hi every body
I have this query
SELECT 20.00::numeric(38,2)
and postgre gives me 20, i need that postgre gives me 20.00

Works for me: (version 8.1)

test=*# SELECT 20.00::numeric(38,2);
numeric
---------
20.00
(1 row)

test=*# SELECT 20.00::numeric(38,20);
numeric
-------------------------
20.00000000000000000000
(1 row)

If the exact output format matters, you should probably use to_char to convert
the number to a string.
