I have a 'transaction' table created in SQL like this:
TranID Date AccNum Type Amount ChequeNo DDNo
657520 02-07-1999 0181432 Debit 16000 465774
657524 02-07-1999 0181432 Debit 13000 569086
657538 09-07-1999 0181432 Credit 11000
657548 18-07-1999 0181432 Credit 15500
657519 02-07-1999 0181432 Debit 12000
657523 02-07-1999 0181432 Credit 11000
657529 03-07-1999 0181432 Debit 15000 466777
657539 10-07-1999 0181432 Credit 10000
657541 11-07-1999 0181432 Debit 12000
657525 03-07-1999 0181432 Debit 15000 569999
657533 05-07-1999 0181432 Credit 12500
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

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>

Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
