Problems with a Query between 7.3 and 8.2

Hi,

I have to migrate an existing System from PostgreSQL 7 and 8.2.
There is a query that I'm not fully understand. It is running with
7.3.21 generating two notices about missing FROM's:

select poid,prodort.bez1 as prodort,sum(anz) as anz,
art,bez1 from best_dat where type='P' and relid=best_hdr.relid
and best_hdr.prod_date='20.04.2008' and poid=prodort.id
group by poid,prodort.bez1,art,bez1
order by poid,prodort.bez1,poid,art,bez1;

NOTICE:  Adding missing FROM-clause entry for table "prodort"
NOTICE:  Adding missing FROM-clause entry for table "best_hdr"poid |       prodort        | anz | art |

The tables are as follows:
                          Table "public.prodort"Column |     Type      |                     Modifiers

PGSQL 8.2.6 bumps out with the following:

# select poid,prodort.bez1 as prodort,sum(anz) as anz,
# art,bez1 from best_dat where type='P' and relid=best_hdr.relid
# and best_hdr.prod_date='20.04.2008' and poid=prodort.id
# group by poid,prodort.bez1,art,bez1
# order by poid,prodort.bez1,poid,art,bez1;
ERROR:  missing FROM-clause entry for table "prodort"
LINE 1: select poid,prodort.bez1 as prodort,sum(anz) as anz,                   ^
t seems, that PGSQL is missing the From Clause for bez1 but there
is a prodort.bez1 in the query...?

How do I wirte this correctly?

THX,

Holm

Add prodort and best_hdr to your FROM-clause in your query, this
behavior follows on the sql-spec.

select poid,prodort.bez1 as prodort,sum(anz) as anz,
art,best_dat.bez1 from best_dat,prodort,best_hdr where type='P'
and best_dat.relid=best_hdr.relid and best_hdr.prod_date='04/20/2008'
and poid=prodort.id group by poid,prodort.bez1,art,best_dat.bez1 order by
poid,prodort.bez1,poid,art,bez1;

I have changed it to the above, can you please take a look over this?

Thanks and thanks to ramasubramanian..

add_missing_from = on

Simple, just turn on the above option in postgresql.conf ....

and restart postgres service.
