Hi Gurus!

Here's what I'm trying to do : I have a database table that has rows for bugs against a few components in the system like so

COMP    BUGNO
------  -----
USRINT     1111
HWARE    1232
USRINT    1021
KERNEL    4384
DRIVER    4894
KERNEL    4398
USRINT    1233

Now, I want to convert this data into a Perl Hash where in the "key" is the faulty component and the "value" is a list of bugs against that faulty component.

Now I have used DBI to get the values and write them to a hash like so 

our $stmt = qq/select component, bug_no from request where status like
+ 'OPEN'/;
our $sth = $dbh->prepare($stmt);
$sth->execute() or die DBI->errstr;
my %hash;
while( my( $comp, $bug_num ) = $sth->fetchrow_array() ) {
    $hash{ $comp } = $bug_num;
}

What's happening here is that data is being overwritten when a new bug comes against an existing component. I want this bug to be appended to the end of that list so that one print of this hash gives me a list of components and bugs that are open against that component like so:

USRINT     1111, 1021, 1233
HWARE    1232
KERNEL    4384, 4398
DRIVER    4894

I'm not able to get this done. Any help is appreciated!
