I have a query:
select cities.name as city, buildings.name as building, pagename, log_date , sum(exhibition_count) as tot
from logrecords join cities on (logrecords.city=cities.num) join buildings on (logrecords.building=buildings.num)
where advertiser = 'Nielsens' and log_date >= '01/01/2004' and log_date <= '01/31/2004'
group by cities.name, buildings.name,pagename,log_date ;
I have migrated a database from a redhat 7.3 box running
[bhughes@compaq3 reports]$ rpm -q postgresql
postgresql-7.2.3-5.73
To a redhat 9 box running :
[bhughes@compaq2 reports]$ rpm -q postgresql
postgresql-7.4.2-1PGDG
and the rows resulting from the query are no longer sorted by log date.
Is this a change since 7.2x?
I can achieve the results I need by adding an order by clause identical
to the group by but this seems counter intuitive since the rows have to
be ordered anyway.
Any tips appreciated.
