Hey Programatic you are also doing the same but you are passing all the column names once by using join & map. Good thought. But in place holders If i place table name its showing a error.

So I replaced my '?' with table name. Then its working good. Even though I used your logic I need to maintain all my column names in array. I want to change that. Here I am writing all columns in program into big arrays which is looking odd. Can I get that coloumn names from db???

Sample (Tested)

#!/usr/bin/perl
use strict;
use warnings;

use DBI;
my $db_date=$ARGV[0]; #04-10-2015

my $hour = "00";
my $db_name   = "ravi";
my $table_name = "CDR";
my $host      = "xxx.xx.x.xxx";

my @CDR_array = ("Total_MO","Total_MO_sucess","MO_userdep_error","MO_s
+ubcrib_error","MO_system_error","Total_MO_success_rate","Total_AO","T
+otal_AO_sucess","AO_userdep_error","AO_subcrib_error","AO_system_erro
+r","Total_AO_success_rate","Total_MT_P2P","Total_MT_sucess_P2P","MT_P
+2P_userdep_error","MT_P2P_subcrib_error","MT_P2P_system_error","Total
+_MT_P2P_success_rate","Total_MT_A2P","Total_MT_sucess_A2P","MT_A2P_us
+erdep_error","MT_A2P_subcrib_error","MT_A2P_system_error","Total_MT_A
+2P_success_rate","Total_AT","Total_AT_sucess","AT_ESMEdep_error","AT_
+network_error","AT_system_error","Total_AT_success_rate","P2P_FDA_cou
+nt","P2P_FDA_success_count","P2P_FDA_success_rate","A2P_FDA_count","A
+2P_FDA_success_count","A2P_FDA_success_rate","Total_Count","Total_TPS
+","Greatest_TPS");

my $dbh = DBI->connect("DBI:mysql:database=$db_name;host=$host;mysql_s
+ocket=/opt/lampstack-5.5.27-0/mysql/tmp/mysql.sock","root","",{'Raise
+Error' => 1});

my $sql = "select ".join ",", map { "sum($_)" } @CDR_array;
$sql .= " from CDR where Date = ? and Hour like ?";

my $sth = $dbh->prepare( $sql ) or die "Cant get prepare";
$sth->execute($db_date, "$hour:%") or die $DBI::errstr;

my @my_array = $sth->fetchrow_array();

print $my_array[1],$/;
print @my_array,$/;

Can I get that coloumn names from db???

You can get table and column names from the db using queries:

my (@tables, %map);
my $q = $dbh->prepare("show tables");
$q->execute or die "Error listing tables";
        
while ( my ($table) = $q->fetchrow_array ) {
    push @tables, $table;
}
$q->finish;
for my $table (@tables) {
    $q = $dbh->prepare("describe $table");
    $q->execute or die "Error describing table $table";

    while ( my $hr = $q->fetchrow_hashref ) { 
        push @{ $map{$table} }, $hr->{Field};
    }
    $q->finish;
}

Now you have a hash %map keyed on table names, whose values are anonymous arrays containing column names. Use this array to build your query:

my $table_name = "CDR";
my $sql = "select ".join ",", map { "sum($_)" } @{$map{$table_name}};
$sql .= " from $table_name where Date = ? and Hour like ?";

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

+(Total_AT_sucess),sum(AT_ESMEdep_error),sum(AT_network_error),sum(AT_
+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.
