I have a transaction table 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 0181433 Debit 15000 466777 657539 10-07-1999 0181433 Credit 10000 657541 11-07-1999 0181433 Debit 12000 657525 03-07-1999 0181433 Debit 15000 569999 657533 05-07-1999 0181433 Credit 12500
My question is: Query the data from transaction table and calculate the total amount debited by cheque, dd and cash for each account and store the result in a spreadsheet? My code is like this:
#!/usr/bin/perl use strict; use warnings; use DBI; use Spreadsheet::WriteExcel; my $dbh = DBI->connect('dbi:mysql:database:3306','prithvi','prithvi') +or die $dbh->errstr; my $sth = $dbh->prepare("SELECT `AccNum`,`Type`,`Amount`,`ChequeNo`,`D +DNo` FROM `transaction`"); $sth->execute or die $sth->errstr; my $workbook = Spreadsheet::WriteExcel->new('query_result.xls'); my $worksheet = $workbook->add_worksheet(); my $row = 0; my $col = 0; my %h; $worksheet->write_row($row++,$col,['Account Number','Cheque Debit','DD + Debit','Cash Debit']); while(my @data = $sth->fetchrow_array) { next unless($data[1] eq 'Debit'); my $result = $data[3] ? "ChequeNo" : $data[4] ? "DDNo" : "Cash"; $h{$data[0]}{$result} += $data[2]; $worksheet->write_row($row++,$col,\@data); } $sth->finish; $dbh->disconnect;
I am not getting the proper output. Where am I going wrong? Please help. Thanks in advance
