Re: *Regarding brin_index on required column of the table

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
