Обсуждение: to_char(0,'FM999.99') outputs 0.
Hi All, I know this question has already been here but still... select to_char(1,'FM999.99') 1 select to_char(0,'FM999.99') 0. and now I want to get rid of that trailing point ! if this bug hasn't been fixed yet, then what is the best workaround? should I say something like this: select case when n = 0 then '0' else to_char(n,'FM999.99') end Good luck! Andrew Surinov
I can see no reason that there is a period after 0 but not after 1. Sure looks like a bug to me. Added to TODO: * to_char(0,'FM999.99') returns a period, to_char(1,'FM999.99') does not --------------------------------------------------------------------------- Andrew wrote: > Hi All, > I know this question has already been here but still... > > select to_char(1,'FM999.99') > 1 > > select to_char(0,'FM999.99') > 0. > > and now I want to get rid of that trailing point ! > if this bug hasn't been fixed yet, then what is the best workaround? > should I say something like this: > > select case when n = 0 then '0' else to_char(n,'FM999.99') end > > Good luck! > Andrew Surinov > > ---------------------------(end of broadcast)--------------------------- > TIP 6: Have you searched our list archives? > > http://archives.postgresql.org > -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 359-1001 + If your life is a hard drive, | 13 Roberts Road + Christ can be your backup. | Newtown Square, Pennsylvania 19073

Oracle result:

1 row selected.
SVRMGR> select to_char(1,'FM999.99') from dual;

1 row selected.
You're right result of to_char(1,'FM999.99') in PG is bug.
There are more things in my TODO, but sorry I haven't time for 7.3. I must
finish some other project in this time. All will fixed in 7.4.

I suggest that an additional pattern filter be created that that only removes padding white space (front and back) and does not affect trailing zeros.
