Hi

I have complex query like for ex      select  distinct
sub_head."vchSubmittersCode" ,rec."vchFileName" ,
rec."vchCusipFundIDSubFundID" , rec."vchFundUnitPrice"  ,
sub_head."vchValuationDate" ,rec."vchAdvisorLabel" from  "table1" rec join
"table2" sub_head on rec."vchSubmittersCode"=sub_head."vchSubmittersCode"
where  rec."bFetch"=false and sub_head."bFetch"=false ;


Even i have already tried with BTREE indexes & HASH indexes on required
columns .distinct query execution time was not reduced


Query taken around 7 minutes time to execute with BTREE indexes & HASH
indexes on required columns


SO please help in reducing the distinct query execution time

Regards

Durgamahesh Manne
