Hi Roland,
look at the execution plan of your subselect. Start sqlplus then
set autotrace on;
SELECT PBK.VARUKORGEANREL.varukorgid, rik2.vare.ean_nr, 'rsm' ,
PBK.VARUKORGEANREL.lagstapris, 0, rik2.vare.varenavn,
rik2.vare.str,
rik2.lev.navn, rik2.vare.hylletxt2,
rik2.vare.sortiment,rik2.art_hierarki.vgrp,
pbk.varukorgeanrel.vare_snr,pbk.varukorgeanrel.varenr,pbk.varukorgeanrel.lev
nr
FROM PBK.VARUKORGEANREL,rik2.vare,rik2.lev,rik2.art_hierarki
WHERE PBK.VARUKORGEANREL.varukorgid= 39
AND PBK.VARUKORGEANREL.ean=rik2.vare.ean_nr
AND RIK2.VARE.ARTNR=RIK2.ART_HIERARKI.ARTNR
AND rik2.vare.levnr=rik2.lev.levnr
AND rik2.vare.selskap='11'
AND rik2.vare.vare_snr=pbk.varukorgeanrel.vare_snr
AND pbk.varukorgeanrel.varenr=rik2.vare.varenr
AND pbk.varukorgeanrel.levnr=rik2.vare.levnr
AND rik2.art_hierarki.sett_id=2;
Look at the results. If there are FULL table scans on large tables you have
to create indexes. If you use Optimizer CHOOSE, look if the tables and
indexes are analyzed.
Hope this will help.
Regards
Volker Schön
