Hello Folks, Given an Oracle 7.3.4 database, how would you tune a query as under, other than suggesting a migration to a higher version. This query is currently performing a lot of I/O, obviously doing a full tablescan on CAMPMAIN.
SELECT CAMPNAME,ASGNMTTYPE,CAMPRTGNUM, LTRIM(RTRIM(CAMPTYPE)) FROM CAMPMAIN WHERE LTRIM(RTRIM(CAMPNAME)) = :b1 AND (LOAD_FAILED_FLG = 'N' OR LOAD_FAILED_FLG = '' OR LOAD_FAILED_FLG IS NULL ); This query runs in a PL/SQL loop. For now, my suggestion was to create a temporary table with all the fields and a fully trimmed CAMPNAME field outside the loop, create an index on this table, and then use this temporary table inside the loop. Any better suggestions?
