Hi,

please forgive if this is a very newbie question. I have course data returned from DB by something like: 

$sql = qq{select course_id,course_name,course_sitting_id,course_sittin
+g_date from courses};
$sth = $dbh->prepare($sql) or die . . .;
$sth->execute() or die  . . . .;
while (@fetch = $sth->fetchrow)
        { . . . .

Which returns data like : 

10,Programming 101,1,01-SEP-2011
20,Databases 101,1,03-SEP-2011
10,Programming 101,2,20-SEP-2011
20,Databases 101,2,27-SEP-2011

I need to get it into the following hash of hashes structure :

my %courses= (
    '10' => {
        'desc' => 'Programming 101',
        'sittings' => {
            '1' => '01-SEP-2011',
            '2' => '20-SEP-2011',
        },
    },
    '20' => {
        'desc' => 'Databases 101',
        'sittings' => {
            '1' => '03-SEP-2011',
            '2' => '27-SEP-2011',
        },
    },
);

But I'm completely stumped . . wish I could show what code I got . . . but I got nothing . . . . Many Thanks.
