Sorry. Its my mistake to not saying for you clearly. Here if I am using join & map its returning all the sum of the columns. but I have percentages in the middle. The percentages also adding and its returning like "590.04%". After seeing this result I changed my program to

my $sql = "select sum(Total_MO),sum(Total_MO_sucess),sum(MO_userdep_er
+ror),sum(MO_subcrib_error),sum(MO_system_error),sum(Total_MO_success_
+rate)/(select count(Total_MO_success_rate) from CDR where Date = '13-
+10-2015' and Hour like '00:%'),sum(Total_AO),sum(Total_AO_sucess),sum
+(AO_userdep_error),sum(AO_subcrib_error),sum(AO_system_error),sum(Tot
+al_AO_success_rate)/(select count(Total_AO_success_rate) from CDR whe
+re Date = '13-10-2015' and Hour like '00:%'),sum(Total_MT_P2P),sum(To
+tal_MT_sucess_P2P),sum(MT_P2P_userdep_error),sum(MT_P2P_subcrib_error
+),sum(MT_P2P_system_error),sum(Total_MT_P2P_success_rate)/(select cou
+nt(Total_AO_success_rate) from CDR where Date = '13-10-2015' and Hour

+serdep_error),sum(MT_A2P_subcrib_error),sum(MT_A2P_system_error),sum(

+system_error),sum(Total_AT_success_rate)/(select count(Total_AO_succe
+ss_rate) from CDR where Date = '13-10-2015' and Hour like '00:%'),sum
+(P2P_FDA_count),sum(P2P_FDA_success_count),sum(P2P_FDA_success_rate)/

foreach my $hour ("00","01","02","03","04","05","06","07","08","09",10
+..23)
{
        $sth->execute($date, "$hour:%") or die $DBI::errstr;
        my @my_array = ();
        push(@my_array,$hour);
        push(@my_array,$sth->fetchrow_array());
        my $col = 0;
        print @my_array,$/;
        foreach my $value (@my_array)
        {
                $sheet->AddCell( $row, $col, $value );
                ++$col;
        }
        $row++;

Its too ugly I know. But have a look. Here I have Percentages & the last column is Greatest tps. To achieve this

sum(A2P_FDA_success_rate)/(select count(Total_AO_success_rate) from CD
+R where Date = '13-10-2015' and Hour like '00:%')
max(Greatest_TPS)

I need to write like this. Now show me a shortcut please.
