@Misc{pgsql,
author = "{P}ostgre{SQL} {G}lobal {D}evelopment {G}roup",
title = "Postgre{SQL}",
howpublished = "\url{http://www.postgresql.org}";,

I'm not sure if the citation list is the right thing for software... There's the name, "PostgreSQL". that should be written like this. There's the web site http://www.postgresql.org, which is the best reference. The people behind it are called "The PostgreSQL Global Development Group".

You can start by looking at the wikipedia entry. Not sure what you mean by citing the db. Are you looking at citing where it comes from, who makes it, what? It can be kinda tough to classify open source software... :) -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

I am using Postgresql to store all my research related data. At the moment I am just finishing my PhD thesis and I want to cite postgresql correctly but can't find how to do it. Could somebody give me an advice?

You do not need that at all, the loop will be left if there are no more results.

Hi, I am trying to use cursors and I am really frustrated already. Do I need to install an extension? 1. Problem number one is that what ever I use in front of the fetch command it is not being accepted, it gives a syntax error. If I use a number ,"all" or "forward" it gives an error again?? I want to do something like the code below: CREATE OR REPLACE FUNCTION database_correction() RETURNS double precision AS $BODY$ DECLARE mycursor CURSOR FOR select distinct(fund_id) from "NAV_values_bfb_history"; iterator integer; BEGIN open mycursor; FETCH mycursor INTO iterator; --fetch next from mycursor --gives an error WHILE (FETCH next from mycursor) LOOP -- some computations here END LOOP; CLOSE mycursor; END; 2. What is the right way to check that the cursor has ended. In sqlserver there is a variable "@@fetch_status". I have to make here some comparison in the while clause, but I am not sure what it should be. I could not find a single example for cursor in a loop. I will greatly appreciate any help, pgsql is my database of choice. Cheers, Anton ---(end of broadcast)--- TIP 2: Don't 'kill -9' the postmaster
