Complete testcase is below.
Should I try 9.0 release or other idea how to fix without removing primary
key and keeping query structure so that query runs in all >=8.1 servers ?
Andrus.
create temp table klient (kood char(12) primary key, hinnak char(5)) on
commit drop;
SELECT *
FROM (select 1) xtoode
LEFT JOIN (SELECT hmguid.toode,
COALESCE(hinnamtr.hinnak,klient.hinnak ) AS hinnak
FROM (
SELECT
hmhinnak.toode,
''::char as guid
FROM (
select ''::char as toode,
1 as prioriteet
) prioriteet
JOIN (
SELECT
''::char as toode,
''::text as guid,
1 as prioriteet
) hmhinnak
USING (toode,prioriteet)
) hmguid
JOIN (select ''::char as guid, ''::char as hinnak) hinnamtr USING (guid)
LEFT JOIN klient ON klient.kood=''
) temphinnaks on true
