in reply to SQL Database Table to Perl Script

Maybe this is what you are looking for.

!/usr/bin/perl use DBI; use strict; use warnings; my $dbh = DBI->connect('dbi:mysql:database','user','password') or die +"Couldn't connect"; my @sql =(); $sql[0] = qq[SELECT AccNum as Account, max(date) as Date, Type, count( +*) as Total_No, sum(Amount) as Amount FROM transaction GROUP BY AccNum, Type union SELECT AccNum, max(date),'Balance', count(*), sum(if(type='Debit',-1*A +mount,Amount)) FROM transaction GROUP BY AccNum;]; $sql[1] = qq[SELECT AccNum as Account, max(date) as Date, Type, 'CHEQU +ENO' as Subtype, count(*) as Total_No, sum(Amount) as Amount FROM transaction where chequeno is not null GROUP BY AccNum, Type union SELECT AccNum as Account, max(date) as Date, Type, 'DDNO' as Subtype, +count(*) as Total_No, sum(Amount) as Amount FROM transaction where DDNO is not null GROUP BY AccNum, Type;]; $sql[2] = qq[desc transaction;]; open (FH, ">".$ENV{"TMP"}."\\mytmp.html") || die "Cannot open temporar +y file: $!\n"; print FH '<HTML><Body>'; foreach (@sql) { my $tran_cur = $dbh->prepare($_); $tran_cur->execute; print FH '<table border=1 cellspacing=0 cellpadding=2><tr>'; map {print FH "<td>$_</td>"}@{$tran_cur->{NAME}}; print FH "</tr><br/>"; while( my @data = $tran_cur->fetchrow_array) { print FH "<tr>"; map {print FH "<td>$_</td>"}@data; print FH "</tr>"; } print FH "</table>"; } print FH "</Body></HTML>\n"; my $url = "file://".$ENV{"TMP"}."\\mytmp.html"; my $commandline = qq{start "$url" "$url"}; system($commandline) == 0 or die qq{Couldn't launch '$commandline': $!/$?}; close FH; $dbh->disconnect; sleep(5); unlink $ENV{"TMP"}."\\mytmp.html" or warn "Could not unlink ".$ENV{"TM +P"}."\\mytmp.html: $!";
