Обсуждение: datetime datatype question
If from the psql command line I use select current_timestamp it shows like this: 1999-10-01 14:30:53-05 However if I insert into a datetime field, when I do a select it formats it like so: Sun Oct 03 10:00:00 1999 CDT Is there a way I can retrieve the information from a datetime field, and format it like the first example ?

Cheers, Patrick PS you could also set the environment variable PGDATESTYLE to ISO...

Yes. Use TIMESTAMP data type instead of DATETIME.
