Query succeeds, but it returns no resul although there should be. The above error happens if a program calls PQgetvalue(), PQgetlength(), or PQgetisnull() with a row number of -1 and if there were no rows in the result. Are you calling those libpq functions directly, or are you using an interface that sits on top of libpq? If the latter, what interface and version are you using? What version of PostgreSQL? What does your code look like? -- Michael Fuhr http://www.fuhr.org/~mfuhr/
Thank you for your quick responce! I don't call them directly. I use pgsql
8.0.3 under
Fedora Core and I'm writing queries through pgAdminIII. This is the query
that produces it:
select
billingplans_freetalktime.id, billingplans_freetalktime.seconds,
billingplans_freetalktime.accumulate, billingplans_freetalktime.period
from (billingplans_freetalktime inner join tariffs
on billingplans_freetalktime.tariff_id = tariffs.id_tariff)
where billingplans_freetalktime.plan_id = 5
and '3597' like tariffs.prefix||'%'
order by length(tariffs.prefix) desc;
and I get this:
row number -1 is out of range 0..-1
Total query runtime: 40 ms.
Data retrieval runtime: 60 ms.
0 rows retrieved.
I'll be glad if you can tell me how can I fix it. Do you know patch or
something?

I would say then that this is a pgAdmin bug, and should be reported on
the pgAdmin mailing lists --- I'm not sure that any of the pgAdmin
hackers read this list.

I do read the list, though I missed it initially. I doubt it's a pgadmin bug, but let's see the query first. Regards, Andreas
