The question is: Query data from transaction table and Calculate the total debit amount and total credit amount for each account. My script is like this:

#!/usr/bin/perl
use DBI;
use strict;
use warnings;
$dbh = DBI->connect('dbi:database','prithvi','prithvi') or die "Couldn
+'t connect";
my $tran_cur = $dbh->prepare("SELECT AccountNumber, Type, SUM(Amount) 
+FROM transaction GROUP BY AccountNumber, Type;");
$tran_cur->execute;
print "<table><tr>";
map {print "<td>$_</td>"}qw(Account Number-Total Debit Amount);
print "<br/>";
print "</tr>";
print "</table>";
while( my @data = $tran_cur->fetchrow_array)
{
 my $rec = join ('-',@data);
 print "$rec\n";
}
$dbh->disconnect;

I am getting the exact output for this. But I have two more questions.

1) Query data from transaction table and calculate the total  balance 
+in each account
2) Query data from transaction table and calculate total amount debite
+d by cheque, dd and by cash for each account.

How can I do this? I just have to replace the SQL query in the above script for the 2 new questions. Please help. Thanks in advance
