Help requested: Is there any way to get the session time with a query. All I afforded to get is the start time of statement execution. HLP PLZ

We don't supply that. My only suggestion would be to create a temp table on session start and put current_timestamp into there. -- 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

I 'm trying to convince my chief to add PostgreSQL to RDBMS 's our software supports. I need to know how to get the session time by a simple query , to prohibit idling on the server. I think this feature would be useful not just for me , so if it can be added ,please, give it your best shot.

If you want it by a query, then log_prefix is not going to help :-( It could perhaps be added as a column to pg_stat_activity? (Which has query_start at the moment, could also have session_start)Not having looked into the details, that could probably be added fairly easy. But I assume it's too late to get something like that into 7.5, even if it's really small :-( Or? //Magnus > -----Original Message----- > From: Anass HAMMEDI [mailto:Anass.HAMMEDI@asais.fr] > Sent: Wednesday, July 07, 2004 10:45 AM > To: Andrew Dunstan; pgman@candle.pha.pa.us > Cc: pgsql-hackers-win32@postgresql.org > Subject: Re: [pgsql-hackers-win32] session time > > I 'm trying to convince my chief to add PostgreSQL to RDBMS > 's our software supports. > I need to know how to get the session time by a simple query > , to prohibit idling on the server. > > I think this feature would be useful not just for me , so if > it can be added ,please, give it your best shot. > > Thanx > > Anass > > -----Message d'origine----- > De : Andrew Dunstan [mailto:andrew@dunslane.net] Envoyé : > mardi 6 juillet 2004 16:57 À : pgman@candle.pha.pa.us Cc : > Anass.HAMMEDI@asais.fr; pgsql-hackers-win32@postgresql.org > Objet : Re: [pgsql-hackers-win32] session time > > > Bruce Momjian said: > > Anass HAMMEDI wrote: > >> > >> Help requested: > >> > >> Is there any way to get the session time with a query. > >> All I afforded to get is the start time of statement execution. > > > > You want session start time?
