Thanks for the pointers. I think I posted the same
plan, may be the variable values changed. Anyway, I changed the query and
now it comes back in 2 seconds. Here is the plan
http://explain.depesz.com/s/n9S
Interesting observation - PostgreSQL takes from 2
seconds to 20 minutes fetch the same data set of 2212 records, with slightly
modified queries. Oracle is consistent (taking under 1 minute in both cases),
though not consistently faster. The modified query is
SELECT PFLMST.MEMSHPNUM,
PFLMST.MEMSHPTYP,
ACCMST.PRGCOD,
CNTINF.EMLADR,
CNTINF.CELISDCOD,
CNTINF.CELARACOD,
CNTINF.CELNUM,
CNTINF.ADRLINONE ,
CNTINF.ZIPCOD,
CNTINF.ADRTYP,
(select ONE.FLDDES from COMONETIM ONE
WHERE ONE.CMPCOD =ACCMST.CMPCOD
AND ONE.FLDCOD='program.member.accountStatus'
AND ONE.FLDVAL=ACCMST.ACCSTA)ACCSTA,
(SELECT ONE1.FLDDES FROM COMONETIM ONE1
WHERE ONE1.CMPCOD =ACCMST.CMPCOD
AND ONE1.FLDCOD='common.member.membershipStatus'
AND ONE1.FLDVAL=PFLMST.MEMSHPSTA )MEMSHPSTA,
INDINF.CMPNAM EMPNAM,
INDINF.PRFADR,
INDINF.GVNNAM GVNNAM,
INDINF.FAMNAM FAMNAM,
INDINF.MEMDOB MEMDOB
FROM PRGMEMACCMST ACCMST
JOIN EAIMEMPFLMST PFLMST
ON ACCMST.CMPCOD = PFLMST.CMPCOD
AND ACCMST.MEMSHPNUM = PFLMST.MEMSHPNUM
JOIN EAICUSPFLCNTINF CNTINF
ON CNTINF.CMPCOD = PFLMST.CMPCOD
AND CNTINF.CUSNUM = PFLMST.CUSNUM
LEFT JOIN EAICUSPFLINDINF INDINF
ON INDINF.CMPCOD = PFLMST.CMPCOD
AND INDINF.CUSNUM = PFLMST.CUSNUM
WHERE ACCMST.CMPCOD= 'SA'
AND UPPER(INDINF.FAMNAM) LIKE 'PRICE'
|| '%'
ORDER BY UPPER(INDINF.GVNNAM),
UPPER(INDINF.FAMNAM),
UPPER(INDINF.CMPNAM)
