I got a query that selects a list of addresses based an occurence at that
location.
this query comes back in less than 2 seconds without a distinct clause on
the concatenated name. When I add the distict clause it takes over 40
seconds. I've tried adjusting various sort area sizes and buffer sizes to
see if I can speed this up. Anybody have a clue if there is something in
particular that I can check.
8.1.6 on NT rules based. wtihout the distinct clause it brings back about
10,000 records.
select DISTINCT LTRIM(L.STREET_ADDRESS_BEGIN||' '||L.STREET_NAME_PREFIX||'
'||L.STREET_NAME||' '||L.STREET_NAME_SUFFIX) WRECKS
FROM LOCATION L,
STREET_REQS SR
WHERE L.ID = SR.ID
AND L.STREET_NAME IS NOT NULL
AND SR.TYPE IN ('KED','KAD')
AND SR.CODE LIKE 'O%'
AND SR.ORIG_STREET_REQ_ID IS NULL
